Hernando Castano

founder of Biene Club
technology consultant & advisor · Berlin, Germany

I started my career working in bioinformatics, moved to embedded systems, then distributed systems and compilers. I've advised startups, run grant programs, and worked as a security auditor. Before founding Biene Club, I was CTO of Entropy Cryptography.

I love helping people solve problems at the intersection of technology, product, and business strategy.
