The problem : You don't have web development skills, months to spare, or tens of thousands of euros to invest — but a free site doesn't look professional enough.
Result : We build you a site that inspires confidence from the first visit, and grows with your business. Delivered in 3 to 6 weeks, at a highly competitive price.

Do any of these situations sound familiar? Let's talk about it!
Your prospects search for you on Google before calling, but your current site doesn't convince them?
A site that presents your business and services with a structure, content and journeys designed for your clients. It turns a curious visitor into a qualified lead: an entry point, not a store.
Your site becomes your best salesperson: it works 24/7, reassures before every meeting, and generates inbound requests. Every page is built around what makes your prospects say yes.
We start by understanding who your clients are and what makes them say yes. The site's structure follows that decision journey. Design comes next, to serve conversion — not the other way around.
From the first idea to going live, a clear method where you stay in control
at every step.
We start by understanding your business, goals and customers. We analyze your competitors and audit your current SEO if a site already exists.
The bonusYou walk away with your site's structure, the exact project scope, and a fixed quote.
We design mockups for your pages, which you approve before any development starts. In parallel, we structure the content.
The bonusYou write in your own words, or delegate the copywriting — without derailing the schedule.
We build the site based on the approved mockups. You follow progress during our weekly check-ins.
The bonusYou can browse a test version from the earliest builds, to validate each step.
We run final checks, set up redirects if needed, install measurement tools, and go live.
The bonusWe then train you to manage your site, so you're independent for everyday changes.

A website is like an iceberg: what makes it solid doesn't show. To avoid bad surprises, we work on 5 invisible points that guarantee your peace of mind and security.
None of this shows up on a mockup, but it's what makes the difference between a site that lasts and one that will need heavy maintenance down the line.
See what our clients sayThere's no “perfect” choice when it comes to building your website. The real question isn't “who's the best”, but “what actually matters for my project”. Here are the ten criteria that determine a website's success.

A premium website for a recruitment AI, where every section turns an abstract concept into something concrete and proven.
Custom website
Starting from€2,000 – €3,000depending on the number of pages, features, and level of design customization.We work on a fixed-price basis: the price is locked in at signature and never moves. A site with specific features (client area, booking, online store, simulator) requires an adjusted budget, priced precisely during scoping.
A successful website is decided before the first mockup. Tick the questions you can already answer.
Generate quote requests, sell online, recruit, reassure prospects? A clear goal drives everything else: the pages, the content, the calls to action.
Prospects, customers, candidates, partners: list your visitors and what each one needs to find in under 10 seconds. That's the foundation of navigation that works.
Fill in a form, call, book, buy? One main action per page, not five. That's what turns a visitor into a lead.
CRM, booking calendar, payments, emailing, recruiting tool: take stock. A form that lands straight in your CRM beats an email that gets lost.
You don't need an exact figure, just an honest range. A serious agency will tell you on the first call what's realistic for that amount.
A trade show, a launch, a campaign? Explain the deadline: it lets us prioritise the pages that must be live on the day and deliver the rest afterwards.
Old site, logo, brand guidelines, photos, copy: share it all. And decide early who writes the content, it's often what delays a launch.
Who approves the mockups? Who will update pages and news after launch? The answer also shapes the back office you need.
Contact requests, traffic, Google rankings at 6 months: pick 2 or 3 metrics. A good agency sets up the tracking from day one.
Bad past experiences, non-negotiables (hosting in France, a site you own, no opaque subscription): say so up front.

Don't have every answer yet? That's normal.
That's exactly what our scoping call is for: 30 minutes to get clarity, no strings attached.
Answers to the questions we get asked most often about building a website.
Count on 3 to 6 weeks between the first scoping call and your site going live. A site with specific features (client area, booking, online store) takes longer, which we price precisely during scoping.
