Frequently asked questions about websites and pricing
Clear answers about website pricing, performance, maintenance, AI and technology choices for modern websites.
Marketing sites
How much does a website built by Numinam cost?
Websites are available in three plans: Landing Page (€2,400), Marketing Site (€5,200) and Editorial Site (€7,900). The price depends on the number of pages, the level of integrations (CRM, analytics) and design complexity. A content management plan is available from €150/month across all tiers — the Editorial Site includes it for the first 3 months. The free 30-minute audit helps define the right plan for your project before any commitment.
How long does it take to build a website?
Between 2 and 8 weeks depending on the plan. A landing page: 2 weeks. A marketing site with up to 10 pages and a blog: 4 to 5 weeks. An editorial site with advanced SEO/GEO strategy and multilingual support: 6 to 8 weeks. I commit to a precise timeline from the start.
Does Numinam build e-commerce websites?
Yes. I build online shops for catalogues of up to several hundred products, with payment integration (Bancontact, Stripe, PayPal) and order management. For simpler projects, I use Snipcart integrated with Astro. For more complex requirements — advanced stock management, multi-currency, B2B portal — I work with Medusa. The free audit helps define the right solution for your project.
Do you rebuild existing sites or only build new ones?
Both. But only when the current site is a genuine obstacle to conversion, credibility or speed. If the problem lies elsewhere, I'll tell you.
Is SEO included in a website built by Numinam?
Technical SEO is integrated from the outset: speed, structured markup, content architecture, Core Web Vitals. For a complete SEO strategy — content, positioning, GEO — I offer a dedicated service. See my SEO & GEO offer.
What is GEO (Generative Engine Optimisation) and why does Numinam integrate it?
GEO stands for Generative Engine Optimisation. It's the practice of optimising your site to be cited in AI-generated responses (Google AI Overviews, ChatGPT, Perplexity). SEO makes you visible in traditional search results. GEO makes you visible in AI answers. I structure your site for both from the very start.
Why does Numinam use Astro instead of WordPress?
WordPress is powerful, but it carries significant technical debt: plugins requiring constant updates, a database to secure, load times that worsen with every addition. It's also the most targeted CMS for cyberattacks — which makes sense given it powers over 40% of the web. Astro generates static sites that are ultra-fast, with a near-zero attack surface and virtually no maintenance. For a marketing site focused on conversion and SEO, it's objectively the better choice.
How does maintenance work after launch?
Thanks to the static architecture, technical maintenance is near-zero — no plugins, no database to monitor. For content updates, you send me what you want published and I handle it. You manage nothing, you break nothing. If you'd prefer to manage your own content independently, I can build a bespoke admin interface for your team — that's what the custom site with CMS offer covers.
Do I keep ownership of my site if I stop working with Numinam?
Yes. The code is 100% yours. No lock-in, no annual licence, no proprietary platform. If you ever want to change provider, you leave with everything.
Are Numinam websites GDPR compliant?
Yes. Sites I build are hosted on European servers, with no superfluous data collection. Contact forms comply with Belgian GDPR requirements — explicit consent, integrated privacy policy, no transmission to undeclared third parties. If your project involves sensitive data or specific processing requirements, this is addressed during the audit so the architecture is compliant from the outset.
FAQ — Website for consulting firms and B2B services
What's the budget for a consulting firm website?
A website for a consulting firm at Numinam starts from €5,200 for a full marketing site (up to 10 pages, SEO blog included). An editorial site with content strategy, thematic silo architecture and CRM integrations starts at €7,900. The price depends on scope: number of pages, content strategy, integrations (CRM, forms, analytics), volume of target keywords. A 30-minute call scopes the project and provides a precise estimate. No surprise quotes: the price is fixed before the first commit.
How do you build a content and thought leadership strategy for a consulting firm?
A consulting firm creates value through its expertise — but that expertise remains invisible if it isn't published and structured to be found. I build content architectures in thematic silos: each practice area (strategy, digital transformation, finance, HR…) has its own content pillar with supporting articles. This structure lets the firm rank on expertise keywords and get cited by AI tools like ChatGPT or Perplexity. Content is designed to demonstrate the firm's competence — not to fill a blog without strategy. I work with you to define priority topics, appropriate formats (in-depth articles, case studies, sector analyses) and the editorial calendar.
SEO or LinkedIn: which channel should a B2B consulting firm prioritise for lead generation?
Both are complementary — but they serve different stages of the client journey. LinkedIn is effective for brand awareness and direct relationships, but organic reach is declining and content has a very short shelf life. SEO, on the other hand, builds a durable asset: a well-ranked article keeps generating qualified visitors months after publication. In 2026, Google AI Overviews and generative AI tools (ChatGPT, Perplexity) cite authoritative sources — your website is the only place where you fully control that content. I build sites combining technical SEO and GEO so your firm is found on Google and cited by AI, whatever your prospects are searching for.
Can a blog and editorial strategy be integrated directly into my consulting firm's website?
Yes — it's at the core of the offering. The sites I build for consulting firms natively include a blog with an optimised SEO architecture: structured URLs, semantic markup, internal linking between articles and service pages. You have two options for content management: I handle it through a monthly editorial retainer (from €150/month), or you manage it yourself with a bespoke CMS if your team wants full publishing autonomy. In both cases, each article is designed to answer a specific search intent and to demonstrate your firm's expertise on questions your clients are actually asking.
Can I connect my website to my CRM for lead nurturing?
Yes. The sites I build for consulting firms can be integrated with the main CRMs on the market: HubSpot, Salesforce, Pipedrive, Zoho, or an internal CRM. Contact forms, content download requests (white papers, studies) and newsletter sign-ups feed directly into your prospecting pipelines. I also configure analytics events (Google Analytics 4, Matomo) to track conversion paths and identify which pages generate the most qualified leads. If your nurturing process includes AI-powered automations, these are integrated from the design phase.
What happens if Sébastien is no longer available — who maintains my site?
This is a legitimate question that any serious consulting firm should ask. Here is my concrete answer: the full source code of your site is delivered to your own Git repository from day one. Every line of code follows industry standards (Astro, TypeScript, documented conventions) — any competent web developer can take over without any transition period. I work with a network of trusted associates who have secure access to projects and can step in if I am unavailable. You are never locked into a proprietary dependency. Unlike a WordPress site with third-party plugins or a SaaS platform, your site is an asset you own outright and can evolve with any provider.
My firm is small (3-5 consultants). Is this suited to my budget?
Yes. The offering adapts to the size of your firm. A full marketing site with SEO blog and CRM integration starts at €5,200 — that's the cost of one or two consulting days billed to your clients. For a small firm, we focus on the essentials: a content architecture targeting 2-3 key themes, service pages that convert, and a well-connected CRM. You don't need 50 pages to start ranking. The advantage of a small firm is agility: you can publish content quickly, test angles, and see the first SEO results within a few months. Then the site grows with you — we add content silos, case studies and service pages as your firm develops.
How long before SEO results for my consulting firm?
Generally, first Google rankings arrive between 3 and 6 months after launch, on the least competitive keywords in your niche. That's the time Google takes to index your content, evaluate your site's relevance and start positioning it. What accelerates things: a well-structured content architecture from the start (that's what I deliver), a regular publishing cadence (even one article per month makes a difference) and a domain with at least some history. The effect is cumulative: each new piece of content reinforces the previous ones. After 12 months, a firm that publishes regularly can generate dozens of qualified visitors per week — decision-makers searching for exactly what you offer. It's an investment that compounds, not an ad spend that stops when you cut the budget.
FAQ — Custom website with CMS
How much does a custom website with CMS cost at Numinam?
A custom website with CMS starts from €16,000. This covers the full design process (wireframes, mockups, iterations), backend development, bespoke CMS, user role management, required API integrations, 3 training sessions and 3 months of post-launch support. The final price depends on project complexity: number of content types, role levels, advanced features (client portal, partner access, dynamic catalogue, configurator). A free 30-minute audit scopes the project and provides a precise estimate.
How long does it take to deliver a custom website at Numinam?
A custom website is delivered in 10 to 16 weeks depending on complexity. The project runs in 4 phases: audit and scoping (weeks 1-2), design and validation (weeks 3-6), development (weeks 7-14), launch and support (month 4+). This timeline includes client validation sessions and iterations. Projects with complex features — client portals, multi-country dashboards, configurators — may require up to 20 weeks.
Do you need technical skills to use the CMS delivered by Numinam?
No. The CMS I deliver is designed specifically for non-technical users. The admin interface is built around your team's real processes: fields match what the team publishes, labels are clear and jargon-free, workflows match the internal organisation. Someone who has never used a CMS can publish a full page in under 10 minutes after one training session. 3 training sessions are included in every project.
What is the difference between an Astro site and a Laravel site at Numinam?
The model choice comes down to one question: who manages content after launch? An Astro site (high-performance websites offering) is an ultra-fast static site where I handle content updates through a maintenance retainer — you send what you want published, I publish it. A Laravel site (custom website offering) includes a bespoke CMS: your team manages content with complete independence, without going through me. Both offerings include bespoke design, integrated technical SEO and a scalable architecture. The difference is organisational, not technical.
Who owns the code when Numinam delivers a custom website?
You do — entirely. At project delivery, I transfer full ownership of the source code to you. No annual licence, no platform subscription, no imposed hosting constraint. You can host the site wherever you choose, modify the code with your own team or another developer, and evolve the architecture without depending on me. The code is fully documented, and technical documentation is provided at delivery.
Is training included in a Numinam custom website project?
Yes. Every custom website project includes 3 CMS training sessions. These sessions are tailored to your team's real use cases: publishing articles, managing a catalogue, administering users, and so on. Bespoke documentation of the admin interface is also provided at delivery. The goal: 3 weeks after launch, your team is fully independent — without depending on me for day-to-day operations.
How does technical maintenance work after a Numinam custom website is delivered?
3 months of post-launch support are included in every project. During this period, I answer questions, fix any bugs and support the team's onboarding. After these 3 months, a technical maintenance contract is available from €200/month. It covers security updates, automatic backups, uptime monitoring and bug fixes. This contract is optional — you are free to manage maintenance internally or through another provider.
Is it possible to migrate from WordPress to a custom Numinam website?
Yes. I handle migrations from WordPress (and other CMS platforms) to custom websites. Migration includes transferring existing content (pages, posts, media), setting up 301 redirects to preserve existing SEO and verifying technical SEO post-migration. If the current WordPress site has specific features (WooCommerce shop, complex forms, integrations), these are analysed during the audit and rebuilt natively in the new architecture. Existing SEO is fully protected throughout the migration.
FAQ — Custom e-commerce website
How much does a custom e-commerce website cost at Numinam?
The cost of a custom e-commerce website depends on the scope: number of products, payment integrations, inventory management system and the level of automation required. A shop built with Snipcart (simple catalogue, Stripe/Bancontact payment, up to a few hundred products) starts at around €5,000 to €8,000. A more advanced e-commerce site with Medusa.js — multi-currency management, vendor portal, order automation — represents an investment from €16,000. In all cases, there are no sales commissions and no monthly subscription to a third-party platform. A 30-minute call is enough to scope your requirements and provide a precise estimate.
How long does it take to deliver an e-commerce website?
An online shop built with Snipcart (product catalogue, integrated payment, order management) is delivered in 4 to 6 weeks. A more complex e-commerce project — dynamic catalogue, multi-stock management, ERP integrations or advanced automation — requires between 10 and 16 weeks. The timeline depends directly on functional complexity and the speed of your sign-offs. The wireframe and validation phase runs before development: what you approve is what gets built.
Why choose Snipcart or Medusa.js over Shopify?
Shopify is a convenient way to get started quickly, but its business model becomes problematic as you grow: sales commissions (0.5% to 2% depending on the plan), a monthly subscription that climbs with features, and no real ability to customise deeply without going through their ecosystem of paid plugins. With Snipcart or Medusa.js, you pay zero commission on your transactions — your margins stay intact. The code is 100% yours, you can host it wherever you choose and evolve it without depending on a third-party platform. For a Belgian shop targeting growth, the 3-year calculation consistently favours a custom solution.
Which payment methods can I integrate on my online shop?
I integrate the main payment solutions suited to the Belgian and European market: Stripe (Visa, Mastercard, American Express), Bancontact (essential in Belgium — accounting for over 50% of online transactions), PayPal, as well as Apple Pay and Google Pay for an optimal mobile experience. For B2B markets, I can also integrate deferred payment solutions (Klarna, Alma) or automated SEPA bank transfers. All integrations comply with PSD2 standards and 3D Secure two-factor authentication.
Will my e-commerce site rank well on Google?
SEO for e-commerce is a topic in its own right. I handle native technical SEO from the development phase: clean canonical URLs for each product and category, Schema.org structured markup (Product, Offer, BreadcrumbList), dynamic XML sitemap, OpenGraph tags for social sharing, and optimised load times (PageSpeed 95+). Product pages and category pages are designed to be both readable by Google and optimised for conversion. I can also support you with a full SEO/GEO strategy to position your shop on high-commercial-intent queries in your sector.
What happens if you are no longer available for my project?
This is a legitimate question I encourage you to ask any provider. Here is how your project is protected: the complete source code of your shop is hosted in your own Git repository (GitHub, GitLab or Bitbucket) — you own it from day one. Secure access is shared with trusted associate developers who know my technical stack. The project is built with standard open-source technologies (Astro, Snipcart, Medusa.js, Node.js) — any experienced developer can take over without a long onboarding period. Technical documentation is provided at delivery. In practice, your shop does not depend on my personal availability — it depends on well-written code and access that you control.
FAQ — Website for HoReCa and tourism
How much does a website for a restaurant or hotel cost at Numinam?
Three plans depending on your needs. Showcase + Menu (site with interactive menu, local SEO, Google Business Profile): €3,500 to €5,500. Direct Booking (+ online booking system, multilingual, automated emails): €7,500 to €12,000. Multi-venue (multiple sites, centralised back-office, PMS integration): from €14,000. The price varies based on the number of languages, the level of automation and specific integrations. In all cases: zero commission on your bookings. A 30-minute call is enough to scope your needs and give you a precise estimate.
How does the Numinam booking system work?
Your customers book directly on your site: choice of time slot (lunch/dinner), number of covers, date, and optionally a specific table. Availability is displayed in real time. Once the booking is confirmed, the customer receives an automatic email and/or SMS. A reminder is sent the day before. In case of cancellation, the time slot is freed automatically. The system syncs with your calendar (Google Calendar or internal tool). You have nothing to manage manually. For hotels, the same principle applies to rooms with availability management and PMS connection.
Can I keep TheFork or Booking alongside my own site?
Yes, and it's the recommended strategy to start with. The goal isn't to cut TheFork overnight, but to build a direct booking channel that gains momentum progressively. Your site becomes your main storefront (local SEO, Google Maps, social media), the platforms remain a complementary channel. Over the months, the share of direct bookings increases naturally — often a 20 to 40% shift within 6 months — and your commissions decrease accordingly.
Is it easy to update the menu or card yourself?
Yes. You update dishes, prices, allergens and photos in a few clicks from a simple interface, without going through a developer. The change goes live immediately, readable on mobile, indexed by Google. No more PDFs. Your daily specials are published in 30 seconds. During the mockup phase, I show you the admin interface before building it so you can validate what you'll be using every day.
How does Numinam optimise my venue on Google Maps?
Local SEO is integrated from the design phase: Schema.org markup for venues (Restaurant, Hotel, LocalBusiness), NAP consistency (name, address, phone) across all pages, Google Maps integration, and content optimised for geolocated searches. I also guide you on managing your Google Business Profile. The goal: appear in the top 3 when a tourist searches for your type of venue in your neighbourhood — on Google and in AI answers from ChatGPT and Perplexity.
Can my site be in several languages for international tourists?
Yes. The site is multilingual FR/NL/EN (or any other language depending on your clientele). Each version is SEO-optimised in its language and indexed separately by Google. If you manage content independently, the admin interface lets you publish in each language independently.
Do the two systems (TheFork and my site) synchronise?
It depends on the platform. TheFork offers an embeddable widget that can coexist with your direct booking system. For hotels, the connection with Booking goes through a channel manager. The goal is to avoid duplicates: every booking, regardless of the channel, updates your availability. The exact configuration is defined during the scoping call based on your current tools.
What happens if Numinam is no longer available?
The complete source code of your site is hosted in your own Git repository from day one. The project uses standard open-source technologies: any experienced developer can take over. Technical documentation is delivered at launch. Trusted associate developers are familiar with the tech stack and can step in if needed. Your site doesn't depend on a single person.
Do I provide the restaurant photos myself?
Yes, photos remain your responsibility. Visual quality is critical for a HoReCa venue — it's what makes people want to book. If you don't have professional photos, I can recommend photographers specialising in food and hospitality in Brussels. On the technical side, all images are automatically optimised for the web: lossless compression, progressive loading, modern formats. Your photos are beautiful AND fast.
FAQ — Real estate website in Brussels
How much does a custom real estate website cost at Numinam?
Three plans depending on the size of your portfolio. Showcase + Catalogue (up to 50 properties, self-managed catalogue, local SEO): €5,500 to €9,000. Lead Generation (50 to 200 properties, CRM integration, multilingual, neighbourhood pages): €9,000 to €16,000. Group or multi-agency (200+ properties, centralised back-office, ERP connection): from €16,000. The price varies based on the number of neighbourhood pages, integrations and automation level. Zero platform subscription, the code belongs to you. A 30-minute call is enough to scope your needs.
Can my agents manage the property catalogue without a developer?
Yes, that's the whole point. The admin interface is built for sales people, not developers. Adding a mandate with photos, price, surface area and location, updating a price, marking a property as sold: everything is done in a few clicks. The site updates instantly. Each listing automatically generates its own SEO-optimised page for the neighbourhood. During the mockup phase, I show you the admin interface before building it so your team can validate their daily tool.
Does the Numinam site integrate with Salesforce, HubSpot or our CRM?
Yes. I connect your site to your existing CRM: Salesforce, HubSpot, Pipedrive, or any other tool via API. Every form (contact, viewing request, valuation) automatically creates a qualified contact in your pipeline, with the relevant property and the source of the enquiry. No more manual re-entry, no more forgotten leads. If you don't have a CRM yet, I can advise on the best solution for your size and needs.
How does local SEO by neighbourhood work at Numinam?
The site is architected to capture geographic searches: 'apartment for sale Ixelles', 'office to let Etterbeek', 'house with garden Uccle'. Each neighbourhood has its own page, optimised with real estate Schema.org markup, location data and specific content. These pages are automatically enriched with available properties in the neighbourhood. The goal: appear at the top of Google when a buyer searches in your area — and be cited in AI answers from ChatGPT and Perplexity.
Can we keep Immoweb alongside the Numinam site?
Yes, and it's the recommended strategy to start with. The goal isn't to cut Immoweb overnight, but to build an exclusive lead channel that gains momentum. Your site progressively captures organic local traffic. Over the months, the share of direct leads increases and your portal dependency decreases. You decide the pace at which you reduce your portal spend based on concrete results.
How long before local SEO generates leads?
Local SEO is faster than general SEO. Well-optimised neighbourhood pages start appearing in Google results within 2 to 4 months for low-competition queries (specific neighbourhoods, precise property types). For more competitive queries ('apartment for sale Brussels'), expect 4 to 8 months. From launch, your optimised Google Business Profile generates visibility on Google Maps. SEO is a cumulative investment: each month, your positioning strengthens.
What happens if Numinam is no longer available?
The complete source code of your site is hosted in your own Git repository from day one. The project uses standard open-source technologies: any experienced developer can take over. Technical documentation is delivered at launch. Trusted associate developers are familiar with the tech stack and can step in if needed. Your site doesn't depend on a single person.
Is team training included?
Yes. Training on the admin interface is included in every plan. Your agents learn to add properties, edit listings, manage photos and mark sales — usually in a 1 to 2-hour session. User documentation is also provided for future team members. The back-office is designed to be intuitive: if your team can use a standard management tool, they'll be able to use the interface from day one.
FAQ — Website for law firms
How much does a law firm website cost at Numinam?
Numinam offers three packages. A Landing Page from €2,400 for a simple showcase with your contact details and practice areas. A Marketing Site from €5,200 with dedicated pages per legal specialisation, local SEO and smart contact forms — this is the most popular option for law firms. An Editorial Site from €7,900 with a legal blog, multi-language FR/NL support and full content architecture. The exact price depends on the number of pages, integrations and design complexity. A 25-minute call is all it takes to scope the project and provide a precise estimate.
Can Numinam create dedicated pages for each legal practice area?
Yes. Each practice area (tax law, family law, corporate law, commercial law, real estate law…) gets its own page optimised for local search. A prospect searching 'tax lawyer Brussels' lands on your dedicated page, not your generic homepage. This page-per-specialisation architecture is at the core of the SEO strategy Numinam builds for law firms. Each page targets the specific keywords for your practice area and captures qualified traffic.
Is it easy to update my law firm's website content myself?
Yes. Numinam delivers a simple and intuitive admin panel. You can add an article about a legislative change, update your availability, modify a practice area page or publish firm news — without touching code and without depending on a service provider. Training is included at delivery for you and your team.
Does Numinam handle FR/NL multilingual for Brussels law firms?
Yes. The multilingual architecture is native in sites built by Numinam, not a plugin added as an afterthought. Each page exists in French and Dutch with its own URL, its own SEO and adapted content — not an approximate automatic translation. For a law firm in Brussels, this is essential: your Dutch-speaking clients need to find your site in their language on Google.
Can I migrate my existing WordPress law firm site to Numinam?
Yes. Numinam takes over your existing content, redirects old URLs (301 redirects) to preserve your acquired search rankings, and handles the DNS transition. Your old site stays online until the new one is validated and tested. The process is seamless: you lose neither your Google positioning nor your visitors during migration.
How long before my law firm is visible on Google with Numinam?
Technical SEO (speed, structure, markup) is in place from launch day with Numinam. First positions on local searches like 'tax lawyer Brussels' or 'family law firm Brussels' typically appear within 2 to 4 months, depending on competition in your practice area. The effect is cumulative: each practice area page and each published article reinforces the previous ones.
What happens if Numinam is no longer available?
Your site belongs to you entirely. The source code is hosted on your own repository, you have all access (hosting, domain, code). The code follows industry standards — any competent web developer can take over maintenance without a transition period. Numinam creates no technical or proprietary dependency. Unlike a WordPress site with third-party plugins or a turnkey solution, your site is an asset you own and can evolve freely.
Is a 25-minute call with Numinam enough to understand my needs?
Yes. In 25 minutes, Numinam reviews your current site, identifies friction points that drive prospects away, analyses your Google visibility for your practice areas and proposes a concrete action plan. You leave with a clear diagnosis and priorities, even if you don't follow through. It's free and with no commitment.
FAQ — SaaS marketing website
How much does a SaaS marketing site cost at Numinam?
Three plans depending on your stage. Landing Page (1 page, conversion funnel, PageSpeed 95+): €2,400. Marketing Site (5 to 10 pages with SEO blog, product pages and pricing): €5,200. Editorial Site (10 to 25 pages, SEO/GEO silo architecture, multilingual, CRM integrations): €7,900. Beyond 25 pages: custom quote. The price covers custom design, technical SEO and delivery in 2 to 8 weeks depending on the plan. A monthly content management retainer is available as an option. A 30-minute call is enough to scope your needs and identify the right plan.
Why Numinam instead of Webflow or Framer for a SaaS?
Webflow and Framer are excellent for a first MVP site. But when you want a structured conversion funnel, dedicated feature pages that rank on Google, advanced structured markup or a truly optimised pricing page, you hit the limits of these platforms. Performance plateaus (poor Core Web Vitals), the CMS is basic, and you're locked into the ecosystem. A custom site gives you total control: PageSpeed 95+, native SEO/GEO, free architecture, code that belongs to you.
Can my dev team work on the Numinam site?
Yes. The site is built with Astro, a standard open-source framework. Your dev team can work on the code at any time — modify a page, add an integration, deploy a change. The code is hosted in your own Git repository, documented, and follows industry conventions. The goal is for your marketing team to manage content independently (via an admin interface or directly in the files) and for your dev team to step in when needed — without depending on Numinam.
How does Numinam optimise a SaaS pricing page?
The pricing page is often the most visited and least polished. I apply UX-validated conversion optimisation principles: recommended plan visually highlighted (price anchoring), annual/monthly toggle with savings displayed, social proof positioned near CTAs, integrated FAQ to address objections before they become drop-offs. Every element has a measurable objective. If you already have traffic, gains are visible within the first few weeks.
What concrete impact on conversion rate?
Every SaaS is different, but the orders of magnitude are consistent: a site with a structured conversion funnel — landing that qualifies, feature pages that address objections, pricing that guides to the right plan — typically converts 2 to 3 times more than a site without a clear path. If your current rate is 0.8%, a target of 2-3% is realistic on the same traffic. On 10,000 monthly visitors, that's the difference between 80 and 250 trials per month.
Does SEO on feature pages actually work for a SaaS?
Yes, and it's one of the most under-exploited acquisition levers. When a prospect searches 'collaborative project management tool' or 'automatic invoicing software', they're in an active comparison phase — purchase intent is strong. A dedicated feature page, structured around that keyword with the right markup and content, captures this intent traffic. The added advantage: these pages are also the ones AI tools (ChatGPT, Perplexity, Google AI Overviews) cite when a user asks for a recommendation.
Who writes the page content?
Three options depending on your situation. I can write the content from A to Z (included in the budget or as a supplement depending on volume). I can optimise the content you provide (restructuring, SEO, conversion copywriting). Or I can work directly with your marketing team or copywriter to produce together. We define the model during the scoping call based on your internal resources.
What happens if Numinam is no longer available?
The complete source code is hosted in your own Git repository from day one. The project uses standard open-source technologies (Astro, Node.js): your dev team or any experienced developer can take over. Technical documentation delivered at launch. Your site doesn't depend on a single person.
Can we migrate from Webflow to a Numinam site?
Yes. Existing content (text, images, structure) is carried over and integrated into the new architecture. If your Webflow site has SEO traffic, 301 redirects are set up on every URL to preserve your Google rankings. The Webflow site stays online throughout the development phase. The switch happens once everything is tested and validated.
FAQ — Web developer for startups
How much does a startup website cost at Numinam?
The budget depends on your stage and goals. A validation landing page (MVP) starts at €2,400. A full marketing site with SEO blog: €5,200. A multilingual editorial site with advanced SEO/GEO strategy: €7,900. If your team needs to manage content independently, a custom website with CMS starts at €16,000. A free 30-minute audit scopes the right formula for your project.
How fast can a startup website be delivered?
Between 2 and 8 weeks depending on scope. Validation landing page: 2 weeks. Marketing site up to 10 pages: 4 to 5 weeks. Editorial site with advanced SEO/GEO: 6 to 8 weeks. I commit to a precise timeline from day one — no deadlines that slip without explanation.
Why choose a freelance developer over an agency for my startup?
With an independent developer, you work directly with the person who designs and codes your site. No project manager in between, no unnecessary meetings, no agency margin. Decisions are faster, your budget goes further, and you have a single point of contact who knows your project inside out. That's exactly what a startup needs: agility and efficiency.
Will my startup website be visible on Google and in AI answers?
Yes. Technical SEO is baked in from day one: sub-1-second load times, structured markup, sitemap, optimised Core Web Vitals. I also integrate GEO (Generative Engine Optimization) so your site gets cited in Google AI Overviews, ChatGPT and Perplexity responses. Being visible on Google is no longer enough — you also need to be cited by AI.
What happens if Sébastien is no longer available? Is my site stuck?
No. A continuity procedure is in place: my associates have secure access to all source code and production environments. In the event of extended unavailability, they contact each client and ensure the transition. Furthermore, you own the entire source code from delivery — it's hosted on your own Git repository. The code follows industry standards, widely adopted framework conventions and includes full technical documentation. Any competent developer or agency can take over maintenance without depending on Numinam.
Can my website evolve as my startup grows?
That's built in from the start. The architecture is designed to evolve: add pages, integrate a blog, go multilingual, connect a CRM or analytics tool. If you reach the stage where your team needs content independence, migrating to a custom website with CMS is seamless — I already know your project.
FAQ — Website for supply chain and transport
How much does a client portal or website for a transport company cost at Numinam?
Three plans depending on your needs. Professional showcase (5 to 10-page site, service presentation, quote request form): €5,200 to €8,000. Client portal (real-time tracking connected to your TMS, automatic alerts, multilingual): €12,000 to €22,000. Operational platform (portal + internal dashboards + full ERP/TMS/WMS integrations): from €22,000. The price varies based on the number of integrations and customisation level. No annual licence, the code belongs to you. A 30-minute call is enough to scope your needs.
Can Numinam build a real-time tracking portal for my customers?
Yes. The portal is connected to your TMS via API: shipment status, vehicle geolocation, automatic alerts at each key milestone (pickup, transit, delivery), proof of delivery accessible online. Your customers access information 24/7 without calling your customer service. Transport companies that deploy this type of portal see a 40 to 60% reduction in tracking calls from the first month.
Can Numinam integrate the portal with my existing ERP, TMS or WMS?
Yes, it's one of my areas of expertise. I develop custom integrations between your portal and your existing systems: ERP (SAP, Odoo, Microsoft Dynamics), TMS (Dashdoc, Shippeo, Transporeon), WMS (Reflex, Generix, Manhattan). Data flows via REST API or webhooks. Before writing a single line of code, I map your data flows to determine the best integration strategy.
Our TMS is old. Can it still be integrated?
Yes, in the vast majority of cases. Even older systems generally have an API (even a basic one), programmable CSV or XML exports, or database access. The data flow mapping done upfront determines the best approach: direct API, file exchange, or intermediate middleware. If your system is truly closed, there's almost always an exploitable entry point. The free scoping call validates technical feasibility before any commitment.
How long to reduce 'where is my parcel' calls?
The effect is immediate once the portal is live and communicated to your customers. In practice: 40 to 60% reduction in tracking calls from the first month. Your customers quickly get in the habit of checking the portal rather than calling, especially if you activate automatic notifications by email or SMS at each key milestone. Your team focuses on exceptions and high-value situations.
My business is international. Can I have a multilingual portal?
Yes. I have direct experience deploying multi-country, multilingual platforms — including Coddy, operating across 9 European countries. Each version is translated, SEO-optimised in its language and adapted to local expectations. Each regional manager can handle their content independently from a custom back-office.
What happens if Numinam is no longer available?
The complete source code of your platform is hosted in your own Git repository from day one. The project uses standard open-source technologies: any experienced developer can take over. Technical documentation delivered at launch. Trusted associate developers are familiar with the tech stack and can step in if needed. Your platform doesn't depend on a single person.
Is team training included?
Yes. Training on the portal and internal tools is included in the Client Portal and Operational Platform tiers. Your teams learn to use the dashboards, manage client access and interpret the data — usually in one to two sessions. User documentation is provided for future team members. The interfaces are designed to be intuitive: if your team can use a TMS, they'll be able to use the portal from day one.

How much does a project with Numinam cost?
It depends on the scope. A quick-win automation project starts at €5,000 and delivers results in 4 to 6 weeks. A high-performance website ranges from €5,000 to €18,000 depending on the number of pages and integrations. Custom internal tools (CRM, dashboards, portals) start at €15,000.
The initial 30-minute audit is free and commitment-free — that's where I define the scope and budget that fits your situation. All price ranges are displayed on the solution pages at numinam.com.
How long does it take to see results with Numinam?
The first automation quick wins deliver measurable results in 4 to 6 weeks: hours recovered, errors eliminated, processes accelerated. A high-performance website is delivered in 4 to 10 weeks depending on complexity.
My approach is designed to prove value quickly — I don't spend 3 months auditing before I start implementing.
Does Numinam work with companies my size?
I primarily work with SMEs of 5 to 100 people, post-seed startups, and growing scale-ups. Whether you're a solo founder who needs a high-performance website or a 50-person SME looking to automate internal processes, my approach adapts.
The free 30-minute audit lets us confirm that I'm the right partner for your situation.
Will AI replace members of my team if I work with Numinam?
No. My goal isn't to replace your team — it's to give them tools that match their ambitions. Automation eliminates repetitive tasks (data entry, reporting, manual follow-ups) so your team can focus on what actually creates value: client relationships, strategy, creativity.
In practice, I automate the work nobody wants to do — not the work that requires human judgment.
Is my data safe with Numinam?
Yes. I apply GDPR standards to all projects. Websites built with Astro are static — no exposed database, no vulnerable plugins, virtually zero attack surface. For internal tools and automation workflows, data stays in your infrastructure or on European servers.
No client data is shared with third parties without your explicit consent.
What's the difference between Numinam and a traditional web agency?
A traditional web agency builds a website and moves on to the next client. With Numinam, you work directly with me — Sébastien, founder and developer. I work across your entire operational efficiency: process automation, high-performance website, custom internal tools, SEO and analytics.
My approach is progressive — I start with an audit, prove value with quick wins, and then build the digital infrastructure. I automated my own company (Coddy, deployed in 9 countries with 100% automated flow) before offering the service to other SMEs.
FAQ — My approach
Do I have to use all 3 pillars (website, automation, tools) with Numinam?
No. The initial audit identifies the combination that will have the most impact for your specific situation. Some clients start with a website alone, others with automation. The holistic approach means I think about the full picture from the start — it doesn't mean I force everything on you at once.
How much does a full Numinam engagement cost?
The audit starts at €2,000 (or free in the 30-minute light version). The build phase ranges from €5,000 to €40,000+ depending on scope — website only, automation only, or a combination of all three pillars. Ongoing optimization is a retainer of €1,000 to €3,000/month. Detailed price ranges are available on each solution page.
How long before I see results with Numinam?
First results are visible within 4 to 6 weeks — whether it's a delivered website, hours saved through automation, or a working internal tool. The initial audit takes 1 to 2 weeks. A full project (website + automation) is deployed in 8 to 16 weeks depending on complexity.
What's the difference between Numinam and a traditional web agency?
A traditional web agency delivers a website and moves on. With Numinam, you work directly with me — Sébastien, founder and developer. I build a digital ecosystem where your website, automations, and internal tools work together. I don't deliver an isolated website — I make sure every lead generated is qualified, routed, and followed up on automatically. And I measure business outcomes, not just traffic.
What if I just want a website, without automation?
That's absolutely possible. The High-performance websites page is designed for exactly that. I'll still recommend thinking about what happens after conversion (lead processing, follow-ups), but you're not obligated to do everything at once.
How does Numinam handle client data and confidentiality?
All data is hosted in Europe (GDPR compliant). I don't share anything with third parties without your consent. Access is limited to those directly involved in the project. And at the end of the engagement, you own 100% of the code and data.
Is the free 30-minute audit at Numinam really free?
Yes. 25 minutes on a video call with me — Sébastien, founder and developer. I review your website, your processes, and your tools. You leave with a diagnosis and actionable insights — whether you choose to work with me or not. No sales pitch, no commitment.
IA & automatisation
Do you automate "everything"?
No. I only automate tasks that are repetitive, time-consuming, and of no strategic value. AI is never an end in itself.
Will AI replace team members?
The goal is to free up time, not to replace humans. Fewer operations, more thinking, more sales, more product.
Is it complicated to maintain?
No. Automations are documented, tested, and designed to be understandable. No black boxes.
Does it work with your current tools?
In most cases, yes. I integrate with what already exists rather than tearing everything down.
How do you measure success?
Time saved, errors eliminated, processing speed, ability to handle higher volumes without hiring additional staff.
What if I don't know what to automate?
That's exactly why I start with an audit. In 25 minutes, I review your processes and identify the three most time-consuming tasks. You leave with a clear roadmap — even if you don't take things further with me.
Numinam
Do you work with all startups?
No. I only work with startups that understand the concepts of speed, impact, and prioritization.
Are you a "classic" agency?
No. I'm an independent developer — Sébastien Balieu. I work as a results-oriented partner, not as a supplier of deliverables.
Do you take on several projects at the same time?
Yes, but not many. Availability and quality take precedence over volume.
And what if you realize that it's not the right time?
I'll let you know. It's better to wait than to launch a project unnecessarily.
Internal tools
What types of internal tools does Numinam build?
I build custom CRMs, real-time dashboards, admin panels, client or partner portals, team management tools, and invoicing systems. Each tool is designed around the company's specific processes — not the other way around. The common thread: replacing spreadsheets and generic SaaS with a tool that fits exactly how your team works.
Why build a custom tool instead of using a SaaS like HubSpot or Pipedrive?
A generic SaaS works fine at first. But when your processes become specific — a particular sales pipeline, complex invoicing logic, business workflows the tool doesn't support — you end up paying for features you don't use while hacking workarounds for what's missing. A custom tool I build for you does only what you need, adapts as you evolve, and often costs less than a SaaS over 3 years (a €1,500/month subscription is €54,000 over 3 years).
Is it risky to build a custom internal tool?
The main risk with internal tools is building too much, too fast, without validation. That's why I work in modules: I deliver a first module in 6-8 weeks, your team uses it, I collect feedback, then I build the next one. Each module works on its own. If you stop after the first one, you still have a working tool. Risk is managed at every step.
How long does it take to deliver an internal tool?
The first module is delivered in 6 to 8 weeks. A multi-module platform takes 10 to 14 weeks with progressive deployment. Complex projects (multi-entity architecture, data migration, deep integrations) span 14 to 20 weeks. At every stage, you have a usable tool — I don't make you wait 6 months before showing anything.
How much does a custom internal tool cost at Numinam?
I offer three tiers: Starter Tool (€15,000 to €25,000) for a first module that replaces your spreadsheets, Growth Platform (€25,000 to €40,000) for a multi-module platform with dashboards and integrations, and Enterprise Suite (€40,000 and up) for a complete infrastructure that replaces your SaaS stack. Pricing depends on the number of modules, integration complexity, and data volume — not the number of meetings.
Will the internal tool replace members of my team?
No. The goal isn't to eliminate roles — it's to free your team from repetitive tasks so they can focus on high-value work. A salesperson who no longer spends 2 hours a day entering data into a spreadsheet is a salesperson with 2 more hours to sell. The tool doesn't replace people — it amplifies their impact.
Does the tool work with your existing software?
Yes. The tool is designed to integrate with your current stack: Stripe, accounting software, email services, project management tools, business APIs. Data flows automatically between systems, with no copy-pasting. If you use a tool that has an API (and most do), I can connect it.
Who owns the tool?
You do. 100% of the code belongs to you. No annual license, no vendor lock-in, no exit fees. The code is documented and maintainable — if you ever want to evolve it with a different developer, you can. You own your tools. Period.
What happens after delivery?
I include 3 months of support and maintenance after delivery (in the Growth Platform and Enterprise Suite tiers). Beyond that, you can subscribe to a maintenance and evolution retainer, or manage it internally — the code is yours. I don't create dependency. If you come back, it's because you want to, not because you're stuck.
We're a small team of fewer than 10 people — is it worth it?
Small teams often gain the most. When you're 5 or 8 people, every hour counts. A tool that saves 10 hours per week for a team of 8 is the equivalent of a part-time hire recovered — without recruiting. The Starter Tool (from €15,000) is sized for exactly this type of team.
Why not build the tool ourselves in-house?
You can. But it means hiring a developer (€50,000/year minimum), managing the project (3-6 months before a first usable result), and maintaining the tool long-term. I deliver a first module in 6-8 weeks, with design, development, integrations, and training included. The question isn't "can we do it in-house" — it's "is that the best use of your time and money."
How does Numinam protect data in internal tools?
Secure authentication, role-based permissions (each user only sees what they need to), encryption of sensitive data, traceable audit logs, GDPR-compliant EU server hosting, and automatic backups. Security is in the architecture from day one — not a patch added at the end.
How do you measure the ROI of a custom internal tool?
I measure 3 things: hours saved per week (how much manual work eliminated), errors removed (duplicate entries, lost data, missed follow-ups), and business impact (better lead tracking, faster invoicing, data-driven decisions). The math is concrete: 10 people × 10 hours saved/week × €35/hour = €18,200 saved per year. ROI is measured in months, not years.
FAQ — UX & UI design
How much does a UX audit cost at Numinam?
A UX audit costs between €2,000 and €5,000 depending on the size of the site and the number of user journeys to analyze. It includes friction point analysis, a competitive benchmark, and a report prioritized by business impact. Delivered in 1 to 2 weeks.
How long does a UX/UI redesign take with Numinam?
A full UX/UI redesign — from audit to final mockups with design system — takes between 4 and 8 weeks. The audit alone takes 1 to 2 weeks. A project with ongoing optimization (A/B testing, monthly iterations) continues as a retainer.
What's the difference between UX and UI at Numinam?
UX (User Experience) covers structure, user journeys, and navigation logic — it's what ensures a visitor finds what they're looking for and takes action. UI (User Interface) covers visual design — colors, typography, components. The two are inseparable: I structure first (wireframes), then design (mockups). Design serves conversion, not the other way around.
Does Numinam do UX design for mobile apps or only websites?
I design interfaces for websites, mobile applications, and internal tools (dashboards, CRMs, client portals). The methodology is the same: audit, wireframes, mockups, interactive prototypes, dev-ready handoff. Every project is designed mobile-first.
Does my team need to be involved in the UX process at Numinam?
Yes, but in a targeted way. I need 2 to 3 validation sessions with your team — one for the audit, one for wireframes, one for mockups. That's about 3 to 4 hours total. The rest of the work is handled entirely by me.
How does Numinam measure the ROI of a UX/UI redesign?
I measure the ROI of a UX/UI redesign through concrete indicators: before/after conversion rate, form completion rate, bounce rate, time spent on key pages. This data is collected via heatmaps, session recordings, and A/B tests. The goal is always measurable business impact, not subjective aesthetic improvement.
What happens to the mockups and design system after the project with Numinam?
Everything belongs to you. The Figma files, the documented design system, the handoff specifications — you own it all. Your team or another provider can reuse and evolve them. No lock-in, no recurring license.
How does Numinam protect user data collected during UX testing?
Data collected during UX tests (heatmaps, session recordings) is anonymized and hosted on GDPR-compliant European servers. I do not collect any personally identifiable data without explicit consent. The tools used (Hotjar, Microsoft Clarity, or equivalents) are configured to exclude sensitive fields.
FAQ — SEO & GEO
What's the difference between SEO and GEO at Numinam?
SEO (Search Engine Optimization) optimizes your site to appear in traditional Google results — blue links, organic positions. GEO (Generative Engine Optimization) optimizes your content to be cited by generative search engines: Google AI Overviews, ChatGPT, Perplexity, Claude. I integrate both from the start. A SEO-only site misses 60% of searches that end without a click. A SEO + GEO site covers both discovery channels.
What is Agentic GEO and why is Numinam already preparing for it?
Agentic GEO is the next evolution of online visibility. AI agents (like ChatGPT Agent, Google Gemini, Copilot) no longer just answer questions — they execute actions for the user: compare, book, purchase. This is the B2A2C model (Business to Agent to Consumer). I prepare your site for this future by structuring your data to be not only citable, but actionable by AI agents — enriched schema markup, transactional content, accessible APIs.
How long before seeing SEO & GEO results with Numinam?
SEO quick wins (technical fixes, existing page optimization) show results in 4 to 6 weeks. Content SEO (new articles, silo architecture) takes 3 to 6 months to produce significant organic traffic impact. GEO visibility (AI citations) can start faster — LLMs reassess their sources continuously, not on a fixed indexing schedule like Google.
Will AI kill traditional SEO?
No. Traditional SEO remains the foundation: 76% of citations in AI Overviews come from the top 10 organic Google results. If you don't rank on Google, AI won't cite you either. What's changing is that ranking alone is no longer enough — you also need to structure your content to be cited. I treat SEO and GEO as complementary, not competing.
How much does a SEO & GEO strategy cost at Numinam?
A full SEO & GEO audit costs between €2,000 and €5,000. A content strategy with optimized article production ranges from €5,000 to €15,000. Ongoing support (monthly production, ranking tracking, optimization) is offered as a retainer between €1,500 and €3,000 per month. Pricing depends on the size of your site, the number of thematic silos, and the level of competition on your keywords.
We already have content — do you start from scratch?
No. I start by auditing your existing content. Articles that are already performing are kept and optimized for GEO (adding structured data, rephrasing for LLM extraction, enriching with verifiable sources). Only low-performing content is removed or merged. The goal is to capitalize on what exists, not throw everything away.
How do you measure AI visibility (GEO)?
I track GEO visibility through several indicators: the number of times your brand is cited in LLM responses (ChatGPT, Perplexity, Gemini), traffic from AI bots (GPTBot, ClaudeBot, PerplexityBot) visible in server logs, and share of voice in generative responses for your target queries. These metrics complement traditional SEO KPIs (rankings, organic traffic, leads).
How does Numinam handle data and confidentiality in its SEO & GEO strategy?
My SEO & GEO strategy is based on public data (rankings, traffic, server logs) and GDPR-compliant analytics tools. No personal data from your visitors is shared with third parties. AI visibility tracking tools analyze public LLM responses — not your users' private conversations.
