Entrepreneur & CTO · Geneva

Building since 2015.

Late co-founder & CTO at YNEO, co-founder of Natives. A growing company's tech on one side, AI products in production on the other.

Portrait of Sébastien Cerdelli

Two hats, one obsession: building

YNEO Late co-founder & CTO

My main focus. I lead the technology strategy behind the growth of flexible office spaces in Geneva. Tech as a lever for efficiency, differentiation and client experience — far beyond IT. Always in the same order: listen first, then build.

What I build

AudioAsk

AI product

Turn any podcast into a source of knowledge: transcription, full-text search and AI answers with timestamped, verifiable citations.

QR-Bell

The intercom, dematerialized: visitors announce themselves by scanning a QR code with their smartphone. No app, no hardware to install.

Well-come

The reception kiosk that takes over from the front desk: it welcomes visitors and connects them with the right person, fully autonomously.

About

Developer first. I started with an IT apprenticeship in Geneva, then a degree in management — and I've never stopped building since.

In 2015, I co-founded Natives with Gregory Chollet. For ten years we've been building and selling our own products to Swiss SMEs — no fundraising, one client at a time. QR-Bell, Well-come, then AudioAsk: every time, starting from a real need and shipping something that works.

Since 2025, YNEO has been my main focus: late co-founder & CTO, applying the same approach — listen first, build second — inside a fast-growing company: technology as a concrete lever, not a gadget.

What drives me: turning an idea into a product people actually use — and today, doing it with AI, putting it in production rather than in demos.

My approach

Technology is not the starting point. It's the consequence of real needs — and it always starts with listening.

I don't comment on AI: I put it in production. Agents, AI-assisted code — never letting go of simplicity that works.

Bootstrapped, no fundraising: products that last and genuinely serve.
