Testimonials

They trusted us.

“Sébastien helped me create my website when I set up as a therapist. This kind of project involves a lot of back-and-forth, and with him the exchanges were always smooth. He's available, attentive to your ideas, and enriches them technically and aesthetically. As someone fairly resistant to digital topics, he was the perfect combo for me: flawless execution and simple, reliable project management. Many thanks!”
Julie Draber Julie Draber Therapist, Gestalt therapy practice
“A true digital craftsman, Sébastien has supported us for over 5 years on all our communication and digital-tool projects. Beyond his always relevant, efficient technical answers, it's his human and professional qualities we remember: insightful on every project, patient with newcomers, able to make technology accessible. The results live up to our expectations.”
Loïc Tytgat Loïc Tytgat Managing Director, APHP du Perche
“Sébastien helped me with the creation and hosting of my site. He's very responsive and professional, and brought me the best solution for my needs. He grasps your challenges very quickly and advises you well. A trustworthy person I recommend without hesitation!”

Frequently asked

You're probably wondering…

Another question? Write to us — we reply fast.

How much does a professional website cost?

It depends on your project and your budget — and we adapt, from small businesses to large accounts. We start at €2,500 for an essential site, then build according to your means and goals, step by step if needed. A complete bespoke showcase site typically goes up to €9,000, and up to €18,000 for an ambitious e-commerce store — but we always scope the project to your budget. The real question is what you own: rental platforms (Wix, Squarespace…) cost €30–50/month once you add the modules, that's €1,800 to €3,000 over five years, and you never own anything — the day you stop paying, your site disappears. With us, you buy a site that's yours. We always provide a clear, detailed quote, after a free first call. We work in euros with clients worldwide.

How long does it take to build my site?

On average 3 weeks for a showcase site, once the content is ready. Our 4-step method (discovery, design, development, launch) is honed to deliver fast without ever sacrificing quality.

Will my site rank well on Google?

Yes — SEO is at the heart of our work. Every site is built with an optimal technical structure, structured data, excellent load times and content crafted around your keywords. We also optimise for AI assistants (Mistral, ChatGPT, Gemini, Perplexity, etc.) that increasingly shape search.

What is a 100% Lighthouse score and why does it matter?

Lighthouse is Google's official tool that scores a site on performance, accessibility, best practices and SEO. A high score means a fast, accessible and technically polished site — which Google rewards with better rankings. Our own site scores 100 in accessibility, best practices and SEO, and we hold every project to that same bar. Performance is optimised to the highest level, but it is a variable score: it depends on test conditions (device, network, server load) and third-party integrations (payment, videos, maps, external scripts). We optimise it to stay as close to the maximum as possible.

Do I own my website and its code?

Yes, unambiguously. Once the project is delivered and paid, the website is entirely yours: design, content, files and source code. You pay for a lasting business asset, not a rental. You're free to host it wherever you like and evolve it with any provider.

Will I be able to edit my site myself?

Absolutely. We hand over a site that's simple to update and we train you to use it. You can also choose our maintenance plan so we take care of everything for you.

Do you work with professionals worldwide?

Yes. We work fully remotely with professionals and businesses anywhere in the world. Everything happens over video calls and email, in English or French, with clear project tracking at every step and time-zone-friendly scheduling.

What happens after my site goes live?

We stay by your side. You get a warranty period, and you can subscribe to our maintenance plan (backups, security, updates, performance monitoring) to keep a fast, secure site over time.
