Web Developer for Startups & SaaS in Paris

Websites for startup & saas in Paris. Most French venture capital sits in Paris, so the site is read by investors as well as by customers, and the two want opposite things. Trying to satisfy both on one page usually satisfies neither. In practice that means two entry points: one page that sells the product and a separate one that carries the traction, the team and the round.

Startup & SaaS expert in Paris

Getting past a directory in Paris means answering a narrower question than the generic one — the arrondissement, the sub-speciality, the exact type of job. That is an editorial architecture decision, and it costs thinking rather than budget.

Dual Engineer + Marketing background (HEC Paris), 200+ projects delivered for SMEs, startups and large corporations. My approach: tailor-made solutions adapted to your sector and your clients.
