Let’s makewhat you & I imagine— real.

I meet people with curiosity, align on what matters, design it, and build it with AI.

Work

I founded Open Orbit Studio to run two-week product sprints: a working build and real customer insight. AI made it cheap to build anything. It did not make it easier to know what sticks.

I founded Meso+ and still bootstrap it, a resistance training app built end-to-end with AI: periodized plans, daily readiness check-ins, and training insights.

I designed for Lepaya in Amsterdam, the power skills training company, which grew from 80 people to 300 in my four years there. The mission was to upskill two million learners in five years. As one of three designers, I led the build of the design system.

I started as an intern, with a mentor who taught me the innovation process. Joining the 30-designer-strong team, I consulted for clients, opening problems with co-creative workshops and design sprints, on products and services that improved the lives of millions.

About

I’m from Vienna. Moved to Stockholm. Now I live in Amsterdam.

Holding my first touchscreen, I wanted to build an app for that.

Started out as a UX design consultant through Daresay, then joined the product team at the EdTech scale-up Lepaya.

In 2025 I founded Open Orbit Studio. Now I build apps like the workout tracker Meso+.

I design services that reach millions to improve people’s lives — sustainably, ideally regeneratively.
