Hi, I'm Alexander đź‘‹
Entrepreneur, 0 to Series-B CTPO, advisor. I love solving tricky problems, scaling startups, and creating space to be awesome for high-performing teams.

About

I started coding at age 9, studied CS @ TUM and spent the last 10 years growing startups as CT(P)O, with the privilege of working with outstanding peers, engineers, investors, and coaches. In between startups, I failed to solve climate change. I ❤️ Technology, leadership, AI, equity, learning, learning, and learning.

Today, I mentor founders, advise investors, and of course, build. :)
