Made with Tea - Jendrik Poloczek

I'm Jendrik Poloczek.

I work on products and companies of the future with inspiring and creative people. I was a machine learning researcher, PhD candidate and a senior software engineer in small and large scale tech companies such as Coinbase. Currently, I'm leading the infrastructure investments team as Principal Research Engineer at the European crypto investment firm Greenfield Capital. My fund investments include Foundation Devices, Stroom, Arcium, BitcoinOS and Drosera.
