Meet Sander

Sander speaks fluent design. With 19 years of experience, he leads design teams and collaborates with stakeholders to build product experiences users love and drive measurable business impact.


"One of the earliest lessons I learned was at Vodafone and Zalando. Working across international teams in London and Berlin taught me how to collaborate across cultures, align diverse perspectives, and operate effectively in complex organizations. It shaped how I communicate, lead, and build trust at scale.

In my opinion, design only succeeds when it delivers measurable outcomes. At
EVBox, restructuring the core funnel led to a 15% increase in sales, reinforcing how directly design decisions influence business results.

Years later, at
Booking.com, I learned the discipline of experimentation and testing at extreme scale. We tested cross platform features with tens of millions of daily visitors. Within minutes, hundreds of thousands of users were using a new hypothesis, providing immediate feedback and clear signals to iterate or move on. That way of working fundamentally changed how I approach product design.

At
SiriusXM, I led and empowered design teams responsible for products used by millions. From presenting to the CEO and 80+ senior leaders to guiding teams through complex decisions, my focus was on connecting design to strategic direction. As Design Lead on a large scale website redesign serving more than 140 million annual visitors, this work delivered a 4.3% lift in conversion.

I lead product teams, partner closely with stakeholders, and work on complex platforms where decisions have real impact. I thrive in ambitious environments and care deeply about creating products that are not only well designed, but drive clear, measurable outcomes."
