About Théo

Your website is your best salesperson: it works 24/7 without complaint. On one condition—that people can find it, and that it makes the phone ring. A beautiful site that no one sees is useless.

I create custom websites for artisans, businesses, and VSEs. No off-the-shelf templates: each site is designed for your profession, your clients, your sector.

What you get:
- A site designed to rank on Google from the start: your clients find you, not the competitor next door.
- Fast (loads in under 2 seconds) and flawless on mobile.
- Integrated appointment booking and contact forms.
- Hosting, maintenance, and security managed: a single point of contact, from A to Z.

The extra edge that almost no one offers: I also make your site visible in ChatGPT and other AIs. More and more people ask an AI, "Do you know a good professional near me?" — you might as well be the one who shows up.

My working method: no fluff, no endless email chains. And above all, I show you a mockup of your site before you pay. You see the actual result, you decide afterward. Delivered in a few days.

The first consultation is free. Describe your project to me, even if it's vague — we'll clarify it together.
