Mathias Van der Brempt

I managed Mathias for 2+ years at 21.co. He’s a calm, structured lead designer who brings clarity to complex problems and grounds decisions in real user needs and constraints. He owned end‑to‑end design for Onyx and BlockSensai, improved usability, shipped the first release, and elevated consistency via the design system, preventing engineering rework. Collaborative, reliable, and forward‑thinking, I’d rehire him without hesitation.

I had the opportunity to work with Mathias for a couple years in 21.co. First indirectly in 21Shares and then directly building BlockSensai. Like any good designer, Mathias has amazing attention to detail and is passionate about the look and feel of every aspect of a product. However, what separates him from other designers is his ability to pursue pixel perfection with the engineers, but also allow them to work quickly and accept trade offs. As anyone can imagine, this is always a constant conversation, but knowing when to push and when to accept is important in all roles and essential between engineers and designers.

It was an absolute pleasure working with Mathias. He lead the UX team on an interim basis last year for the Credit Suisse Digital launch. He delegated tasks effectively and mobilised all UX testing required. As a UX designer, he solves problems collaboratively with the Business, Delivery and Technology teams. He created prototypes demo quickly, took initiative to learn the business to design features that are user friendly. He is highly engaged, listens and proactive - what every team would need.
