Built and Scaled.

I don't just advise. I've built from the ground up. Over the last 10+ years, I've founded and scaled successful tech companies, primarily in the energy and greentech sectors. Previously, I was founding partner of Fünf Prozent and co-founder & managing director of metergrid. My academic foundation is in computer science (PhD) from the Technische Universität Berlin.

You can find me on Mastodon, GitHub and LinkedIn. I also run a blog. If you like, you can book a call with me via Cal.com.
