Studio
We build the software you can't buy off the shelf.
KYN is a founder-led studio for startups and entrepreneurs. We find the real problem, build the system that solves it, and ship it to production — typed, tested, and yours.

We start where you are, then set one objective worth solving.
Most projects fail not because they're built badly — but because they solve the wrong problem.
KYN is a founder-led studio. Florian Lepage leads every build and brings in trusted engineers when a project needs it. One question drives the work — what actually works today? — then we implement a system that answers it, that can evolve over time, tested and shipped to production.

The studio(About)
You have a project idea but you're lost in the tech. We're the partner that turns it into working software — from the first sketch to production.
A founder-led studio: Florian Lepage leads every project, with trusted engineers brought in when the work calls for it. Startup or established company, you get senior technical expertise behind your vision — and someone who stays with it once it ships. We're at home in hard, technical products: real-time data, AI integration, payments and on-chain systems.
