About William Bryk

I grew up in NYC, then studied CS and physics at Harvard, where I did some ML research and led the robotics club. Then I was a software engineer at ML startup Cresta, while also writing a book about the history of civilization in my spare time. When I realized the future of civilization depends almost entirely on the quality of information we consume, I left to start Exa.
