Pamela Vagata is a Managing Partner and co-founder of Pebblebed, and one of the most consequential engineers, researchers, and investors in the history of modern AI. A pioneering computer scientist whose career spans the full arc of the intelligence revolution, she has been present at — and instrumental in — every major inflection point in the field: the platforms that made AI production-ready, the labs that defined what was possible, and now the fund backing the next generation of founders who will do it all over again.

At Facebook, Pam created FBLearner Flow — the machine learning platform that became the backbone of AI across the entire company, enabling millions of training runs and powering every major product at a scale that had never been achieved before. It set the standard for how large organizations build ML infrastructure.

She was a founding member of OpenAI, where she helped establish the engineering foundation that made transformative research possible. She later led AI engineering at Stripe, bringing machine learning discipline to one of the most complex financial systems in the world.

Pam co-founded Pebblebed to back founders who build the way she built — deep in the stack, serious about correctness, and oriented toward the question that has defined her career: what happens when this actually works?
