Greg Brockman is the CEO and co-founder of OpenAl, the nonprofit artificial intelligence research company he co-founded with Elijah Sutzkever, Sam Altman and Elon Musk in December 2015. He co-directed the development of the OpenAl bot that defeated the best human professionals in single-player matches of the video game Dota, and runs the company every day: he is also a board member of Stellar, a nonprofit foundation that creates blockchain to move money across borders in fractions of a penny. His work at Al has earned him a spot on Forbes' 30 Under 30 list for corporate technology. Before OpenAl, he was CEO of Stripe (now valued at $9.2 billion), which he helped grow from four to 250 employees. Brockman dropped out of both Harvard and M.IT.
