Matt O'Brien

I'm the co-founder and co-CEO of System 3, the company behind Relay — local-first software that lets your team and your AI work together in the same files, without giving up ownership or privacy.

Before this, I spent a decade building products in San Francisco — AI at Meta, mindfulness at Lumosity, and digital therapeutics at Big Health — after starting out building software companies of my own.

I studied philosophy at the University of Chicago and depth psychotherapy at Pacifica in Santa Barbara. I see a small number of therapy clients.
