About Mathieu

Available this week, response in under an hour.

Stop beating around the bush, let's frame your product together and in 1 week you'll have your MVP ready to meet your users.

WHAT I DO

01 — Framing & UX and product specifications (the basis of your PRD)
We dismantle your idea until we understand what really matters.

02 — Specifications (your PRD)
We make it clear enough for anyone to build it without interpretation.

03 — Exploration (a first prototype without a database, we fake it together until you make it)
We test the risky points immediately.
What doesn't hold up, we discard it.

04 — Strategy
We arbitrate.
Not on intuition. On what has withstood.

05 — Design system (I write the core of the system that will help launch your product)
We structure to avoid rebuilding twice.

06 — Build (I build your product and ship it through the appropriate channels)
We put a first usable version online.
Not perfect. But real.

07 — Support
I stay until you are autonomous in these decisions.

THREE TRUTHS

01 — Framing has become the main lever.
Everything else is becoming trivial.

02 — You can explore, so you MUST explore.
You have no more excuses for inaction.

03 — Going fast is useless.
Going fast in the right direction, yes.

Take advantage of my 15 years of experience condensed to drastically accelerate your go-to-market without missing what matters: the real value you deliver.
