Alex and Dmitri met in 2017 while working at the Human Dynamics lab at MIT in 2017 on a decentralization project aimed at privacy-preserving data sharing. Both have since worked in decentralized projects since, Alex as a software architect working with the Ethereum blockchain and Dmitri as a decentralized systems engineer at MIT and various startups. Both share a frustration with how people connect, and how inefficient business cards as we currently use them are.
