Mathieu Delvaux

I design and build products.

I’ve worked with incredible companies like Belgian Mobility Company, NMBS‑SNCB,
 STIB‑MIVB, De Lijn, Proximus, Microsoft, Europcar, Swedish House Mafia, and SIZE Records.
I’ve crafted mobility solutions used by millions, shaping how people navigate cities with seamless, real-time transport experiences. My work bridges technology and design to create seamless, user-centered systems. I’ve also built digital ecosystems that connect global communities, bridging technology, design, and culture.
Quality isn’t accidental, it’s intentional. I believe that great design comes from rigorous iteration, thoughtful execution, and collaboration with research and engineering teams. Attention to detail isn’t just a preference, it’s essential to creating intuitive and impactful experiences. Blending strategy, usability, and innovation is what makes products truly resonate.
