Founder’s note

The website we wish we could have bought

Like many business owners, we paid over €10,000 for a website. It kept changing, it was poor quality, and it never brought us a single opportunity.

It was my first company, founded with my brother Lucas. We believed in it and gave it everything: three years, partners like SNCF, Vinci and Lyon Airport. Our website just didn’t keep up.

Out of frustration, we learned it all again: design, code, and everything else. And we found out we loved it.

Since then, that mistake has become our engine. With Croissant, we spare small and mid-sized businesses the trouble we went through.

Today, every website we deliver has one goal: to bring you the opportunities ours never gave us.

To get there, we take the time to understand your business and your clients. Every project is, above all, a collaboration: together we build a website that reflects who you are and supports you over the long term. That’s how we’ve worked with more than 70 companies.

Our mission: a website that works as hard as you do.
