What we build

KYN is a founder-led studio for startups and entrepreneurs. We find the real problem, build the smallest system that solves it, and ship it to production — typed, tested and yours. Pick the work that fits, or just start a project.

Who it's for

Founders and teams who need senior engineering without hiring a senior team — from a first MVP to a production product that has to hold up. One studio, end to end: strategy, design and engineering.

The problem

Most builds fail slowly: the wrong scope, code no one can change, an agency that disappears at launch. We scope to the real problem, build it to stay safe to change, and stay with it once it ships.

FAQ

How fast can you start?

Usually within a week or two. A first call scopes the work; a fixed proposal follows within a few days.

Do you work with early-stage startups?

Yes — most of our work is MVPs and first production products for founders. We scope to what proves the idea, not a feature wishlist.

Who actually does the work?

Florian Lepage leads every build and brings in trusted engineers when a project needs it. You get senior engineering, not a hand-off to juniors.

What happens after launch?

We handle domain, hosting and upkeep, and stay reachable for changes. Small fixes are free, applied within a few business days.
