Hi, I'm Matthieu
I've spent 15+ years helping organizations create new value: first in China (Techstars, XNode) and then across Europe with Mach49 building ventures inside Fortune 1000 companies.
These days, I split my time between consulting and building my own products. The patterns I kept seeing became the tools on this page: Lisa Listener for problem discovery, Forward for teaching entrepreneurship, NewReLLM for revenue strategy.
They're all connected by the same question: how do you build ventures better?
