Prove it before you build it.

A hands-on partner for founders who'd rather de-risk an idea than gamble a budget on it.

Real product. Real users. Real revenue — not a deck.

— The Problem —

Most projects don't fail at launch. They fail at the handoff — between your vision and someone else's execution.

Agencies build what's in the brief. Freelancers build what they're paid for. Nobody else in the room is betting on the outcome the way you are.

My Lean App bets with you.

— The Proposition —

Four phases. One shared outcome.

Every partnership follows the same lean sequence — enough structure to stay disciplined, enough flexibility to follow what the market actually tells us.

  1. 01

    Diagnose

    Pressure-test the idea, the audience, and the business model before a single screen is designed.

  2. 02

    Design

    Turn the validated concept into flows, interfaces, and a build plan that won't need to be redone.

  3. 03

    Prove

    Put a working version in front of real users and let their behavior — not opinions — decide what's next.

  4. 04

    Ship

    Launch the product, wire up the metrics, and hand you a business that runs without a permanent retainer.

— The Proof —

Run by someone who has shipped the whole arc.

Christophe built a lean digital agency from nothing, ran it, and sold it — living through every phase this partnership is built on.

Since then, he's gone back to first principles: which parts of that process actually mattered, and which were just billable noise. Only the former survived.

My Lean App isn't a vendor you manage. It's a co-founder who happens to also build.

— The Approach —

Fast is not the goal. Right is.

We'd rather spend a week validating than a quarter building the wrong thing. Every phase exists to remove a specific risk — market, product, or technical — before money is spent on the next one.

No bloated roadmaps, no technical debt disguised as velocity. Just the shortest honest path from question to revenue.

— Let's talk —

Got something worth de-risking?

Tell us where it stands.

We take on a small number of partnerships at a time, by design. If there's a fit, we'll tell you plainly — and if there isn't, we'll tell you that too.
