Julian Riebartsch

CEO & Co-Founder

Hi there👋
I am CEO and co-founder of Calvin Risk. My academic background is computational physics with a degree from ETH Zurich. In particular, I focused on the development of AI-based forward modeling software of astronomical surveys and dark matter experiments. During the last 4 years, I have worked in Venture Capital, supporting and financing Europe’s upcoming industrial software and hardware companies, most recently at btov Partners.
Aside from my desire to help companies transition to high-value, high-performance, low-risk AI, I am passionate about getting to know other cultures and people, kiting into the sunset, and learning more about new technological paradigms! 🤓
