Jérôme de Tychey
Entrepreneur, economist, experienced executive and ecosystem builder. As President of Ethereum France and founder of EthCC, I actively help shape the global blockchain industry. As founder of Cometh, I build regulated rails for the decentralized finance industry. Over the years, I have scaled and led organizations of over 300 people, drawing on my leadership experience at EY, ConsenSys, and Ledger. I also bridge industry and academia by teaching economics and blockchain technologies at leading universities.
I work on smart accounts and onchain finance infrastructure at Cometh. I run EthCC — the largest annual European Ethereum conference — and teach economics at Le Cnam. This is where I publish notes and talks.
