Sébastien Balieu, founder of Numinam, which creates websites and landing pages

Content, design and development brought together around your marketing objectives.

Numinam is led by Sébastien Balieu, co-founder of Coddy. His experience in marketing and development allows him to design a site that attracts the right visitors, answers their questions and makes it easier to get in touch.

  • An easier project to follow

    You communicate directly with the person who writes and develops your pages. We choose the priorities together, with validation steps defined at the start.

  • Answers to your prospects' questions

    Your visitors want to know if your offer is right for them and why they should trust you. The pages answer these questions before offering a quote, reservation or purchase.

  • Requests forwarded to your team

    Forms transmit useful information to the people who need to respond. We check this tracking before putting it online.

See my journey

A website creation adapted to your way of finding customers.

Your site no longer reflects your offer? A campaign attracts visits without generating requests? We choose the pages to create or rework depending on what is holding you back.

Website creation

Your future customers need to understand what you offer and who you are talking to. I create a site that presents your services, provides proof and facilitates contact.

Website redesign

Has your site aged or no longer corresponds to your offer? I take over the content, presentation and navigation, taking into account the pages that already bring you visits.

Pages dedicated to your campaigns

Your campaign deserves a page that repeats its message. I create this landing page around a specific action: request a demo, register or purchase.

Easier contact

A form that is too long or a poorly explained next step can discourage a prospect. I simplify the process and specify what happens after his request.

Monitoring of requests received

You want to know what your site brings to your marketing actions. I set up tracking of forms, appointments or purchases to identify the pages that generate these actions.

How your website creation project takes shape.

  1. We specify your objectives

    We specify your offer, your customers and the expected action. We also look at where visitors will come from: search, advertising, social networks or recommendations.

  2. I organize the pages and messages

    I build the course and write the content based on your expertise. Each page answers the questions that precede making contact.

  3. I design the screens

    I prepare the design for computer and mobile. We validate the presentation of the offer, the evidence and the calls to action before development.

  4. I develop and connect the site

    I build the pages, forms and planned integrations. I work on speed, mobile display and the technical basics of SEO.

  5. We check and publish

    I test journeys, receiving requests and tracking conversions. For a redesign, I also prepare the necessary redirections.

  6. We measure and improve

    We observe the requests received and their quality. The results help us decide what to do next: adjust a message, simplify a step or develop a new page.

The requests received help us choose the next improvements.

The return of the accompanied teams.

Jean Verheyen
At Nallian we build solutions that are trusted by the world's leading airports, ground handlers and logistics companies. But our website no longer reflected that level of excellence. This redesign ensures our first impression matches the quality of what we actually deliver.

The new website much better reflects who we are. It tells our story more clearly, it's easy to navigate, it looks fresh and modern. It is more Nallian.

Your questions about website creation.

Does Numinam write the texts for the website?
I take care of the writing based on your expertise. You provide information on your offer, your customers' questions and your achievements. We plan your returns and validations in the calendar.
Does Numinam create complete sites and landing pages?
Both. I create business websites, sites with content management and landing pages. The format depends on your offer, your traffic sources and what your visitors need to be able to do.
How much does it cost to create a website at Numinam?
A landing page starts at €2,380 excluding VAT, a business website at €4,760 and a CMS website at €9,520. Scope and launch timing are agreed separately. The website budget guide explains formats and ongoing costs. Check the Brussels grant conditions before starting; an award is not automatic.
How can we compare website proposals?
Give suppliers the same brief and compare content, design, migration, integrations, tests and support. Add expenses left to your team before comparing totals. The supplier comparison guide lists the commitments to request.
How long does it take Numinam to create a website?
The schedule depends on the scope and availability of content. We set the steps and validations before starting. A campaign landing page and a multilingual redesign require different timelines.
Can Numinam improve an existing website?
Yes. I start by looking at the pages, paths and data available. We can intervene on messages, forms or certain pages, or plan a broader overhaul if it is justified.
Do you do A/B testing?
Yes, when traffic and conversions support a useful comparison. Define sample requirements and stopping conditions first. At low volume, fix observed problems and monitor enquiries and opportunities. The B2B conversion guide explains what to measure.
Is SEO included in the creation of the website?
I plan the basics of SEO in creation: structure of pages, titles, internal links and technical elements useful for indexing. The regular development of content and visibility can continue with dedicated SEO support.
Will I be able to modify the site myself?
If your team needs to publish regularly, I plan to have a content management interface within the scope. We define the elements that you must be able to modify and I support you in handling them.
How is form and tracking data managed?
We specify the necessary information, the people who will have access to it and the tools who will receive it. I configure the forms and measurement according to these choices, integrating the necessary consent mechanisms.

Could your site bring you more requests?

Share your site, your campaigns and the requests you want to generate. Numinam helps you determine whether to improve a few pages or launch a more complete website creation.
