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 agents work together in markdown files, without giving up privacy or control.
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 psychology at Pacifica in Santa Barbara. I work with a small number of coaching clients.

Unix is the nearest common ancestor of modern computing. Its bet: text as the universal interface.

Non-developers can chat with AI, and AI can use any programmatic tool — so non-developers can access the developer stack.
The cost of learning to program is no longer front-loaded
Learning to program used to demand a big upfront investment before any payoff. Language models changed the shape of the curve.
We don't charge for privacy
The difference between “we promise not to look” and “we can't look” shouldn't cost extra. Sovereignty isn't ours to sell.
