Hamburg, Germany

Hi, I'm Stephan.

Founder, software engineer, aerospace engineer by training.

I've run verlingo, a B2B HR-tech SaaS, for over ten years. It's used by 400+ companies across Germany.

What I've built

The companies and tools I've founded, shipped, and still maintain. Some are ten-year commitments, some are experiments that grew.
