What I'm building

Where I'm putting energy right now

Kleinanzeigen

Millions of listings, billions of queries. The #1 second hand marketplace in Germany challenges our teams to deliver value at scale.

Faust AI

Consulting with an early-stage AI startup — helping shape product strategy, sharpen positioning, and connect the dots between what the technology can do and what customers actually need.

Glastrix

Building a smart NFC business card platform as a joint venture — Eric brings the printing infrastructure, I build the digital layer.

Where I come from

Ten years across marketplaces, B2B SaaS platforms, and AI systems. Hover any node to explore.

What ties it together: stepping back, finding the actual problem, build a system open to learning, measure & iterate.
