Frequently asked questions about websites and pricing
Clear answers about website pricing, performance, maintenance, AI and technology choices for modern websites.
Marketing websites
How long does it take to get a website developed by Numinam?
Between 4 and 16 weeks depending on complexity. A high-performance brochure site: 4-6 weeks. A site with SEO blog, multi-language and integrations: 6-10 weeks. A full digital infrastructure: 10-16 weeks. We commit to a timeline from day one.
Does Numinam redesign existing websites or only build new ones?
Both. But only if the current site is a real barrier to conversion, credibility or speed. If the problem lies elsewhere, we'll tell you.
Is a website built by Numinam designed to sell, generate leads, or impress investors?
All of the above. A good website must convert prospects and inspire trust — whether for clients, partners or investors. We focus on structure, messaging and credibility before aesthetics.
Does Numinam collaborate with the client's marketing or product team?
Yes, and often with both. The website is a convergence point between acquisition, product and business messaging.
Is SEO included in a website developed by Numinam?
Technical SEO is built in from the start: speed, structured markup, content architecture, Core Web Vitals. For a full SEO strategy — content, positioning, GEO — we offer a dedicated service. See our SEO & GEO offering.
What is GEO (Generative Engine Optimization) and why does Numinam integrate it into its websites?
GEO stands for Generative Engine Optimization. It's about being cited in AI-generated answers (Google AI Overviews, ChatGPT, Perplexity). SEO makes you visible in traditional search results. GEO makes you visible in AI-generated responses. We structure your site for both from day one.
Why does Numinam build its websites with Astro instead of WordPress?
WordPress is powerful, but it carries heavy technical debt: plugins that need constant updates, a database to secure, and load times that increase with every addition. It's also the CMS most targeted by cyberattacks — unsurprisingly, it powers over 40% of the web. Astro produces ultra-fast static sites with virtually no attack surface and almost zero maintenance. For a marketing website focused on conversion and SEO, it's objectively better.
How does maintenance work for a Numinam website after launch?
Thanks to the static architecture, technical maintenance is close to zero — no plugins, no database to monitor. For content updates, we offer a plan where you send us what you want published and we handle it. You don't manage anything. You don't break anything.
Am I able to manage my website independently after Numinam delivers it?
By default, we handle the platform and content updates through a maintenance plan. You send us what you want published, we take care of it — zero hassle. If you'd rather manage things yourself, we can build a custom admin interface so your team is fully autonomous. Both models work — it depends on what suits you best.
Do I retain ownership of my website 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 switch providers, you leave with everything.
Can a website built by Numinam evolve if my business pivots?
That's built into the plan. The architecture is designed to evolve quickly without rebuilding from scratch. We know that version 1 is never the last.

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 we define the scope and budget that fits your situation together. 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.
Numinam's approach is designed to prove value quickly — we don't spend 3 months auditing before we start implementing.
Does Numinam work with companies my size?
Numinam primarily works 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, the approach adapts.
The free 30-minute audit lets us confirm that Numinam is the right partner for your situation.
Will AI replace members of my team if I work with Numinam?
No. Numinam's 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, we automate the work nobody wants to do — not the work that requires human judgment.
Is my data safe with Numinam?
Yes. Numinam applies GDPR standards to all its 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. Numinam works across your entire operational efficiency: process automation, high-performance website, custom internal tools, SEO and analytics.
The approach is progressive — we start with an audit, prove value with quick wins, and then build the digital infrastructure. Numinam's founder automated his own company (Coddy, deployed in 9 countries with 100% automated flow) before offering the service to other SMEs.
FAQ — Our 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 we think about the full picture from the start — it doesn't mean we 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 web agency delivers a website. Numinam builds a digital ecosystem where your website, automations, and internal tools work together. We don't deliver an isolated website — we make sure every lead generated is qualified, routed, and followed up on automatically. And we 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. We'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). We don't share anything with third parties without your consent. Access is limited to project team members only. 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. 30 minutes on a video call with Sebastien, the founder. We review your website, your processes, and your tools. You leave with a diagnosis and actionable insights — whether you choose to work with us or not. No sales pitch, no commitment.
IA & automatisation
Do you automate "everything"?
No. We 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 our current tools?
In most cases, yes. We 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 we start with an audit. In 30 minutes, we 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 us.
Numinam
Do you work with all startups?
No. We only work with startups that understand the concepts of speed, impact, and prioritization.
Are you a "classic" agency?
No. We operate as a small, results-oriented external product team, not as a supplier of deliverables.
Do you take on several projects at the same time?
Yes, but not much. Availability and quality take precedence over volume.
And what if you realize that it's not the right time?
We'll let them know. It's better to wait than to launch a project unnecessarily.
Internal tools
What types of internal tools does Numinam build?
Numinam builds 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 built by Numinam 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 Numinam works in modules: we deliver a first module in 6-8 weeks, your team uses it, we collect feedback, then we 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 Numinam 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 — we don't make you wait 6 months before showing anything.
How much does a custom internal tool cost at Numinam?
Numinam offers 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 Numinam tool work with our 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), we can connect it.
Who owns the tool built by Numinam?
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 team, you can. You own your tools. Period.
What happens after Numinam delivers the tool?
Numinam includes 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. We 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. And Numinam's 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. Numinam delivers 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 our 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 Numinam internal tool?
We 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 at Numinam 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 at Numinam. 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. At Numinam, the two are inseparable: we 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?
Numinam designs 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. Numinam needs 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 Numinam.
How does Numinam measure the ROI of a UX/UI redesign?
Numinam measures 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. Numinam does 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. At Numinam, both are integrated 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). Numinam prepares 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. At Numinam, SEO and GEO are 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 — does Numinam start from scratch?
No. Numinam starts 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 does Numinam measure AI visibility (GEO)?
Numinam tracks 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?
Numinam's 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.
