About Matthieu

Good research doesn't just answer questions. It changes the direction of a product.
That's what I've spent the last 10 years doing - helping product teams move from assumption to clarity, and from insight to decision.

🔍 I'm a UX Research consultant and the founder of PRAXIS. I work with companies navigating complex digital systems, where the stakes are high and the user needs are poorly understood. My job is to surface what teams don't yet know about their users - and make sure that knowledge actually shapes what gets built.

📐 I combine qual and quant methodologies into custom research plans, then stay in the room to apply findings through workshops, facilitation, and hands-on collaboration. Research that ends as a slide deck isn't research that works.

🌍 I've been fortunate to build this practice across continents. Six years in the United States, a year in London, another in Santiago de Chile. That breadth has shaped how I think about users, teams, and the assumptions we carry without realising it.

📍 Today, I'm based in Paris and work with clients worldwide.
If you're building something complex and need a research partner who will tell you the truth about your users - let's talk.
