Series Y: Making Small Bets on Big Ideas


Sam Altman
Y Combinator &  OpenAI 


In 2014, Sam Altman took the helm of Y Combinator, renowned Silicon Valley accelerator known for churning out unicorns including Dropbox, Airbnb, and Stripe. With a mandate to grow as fast as he could, Sam focused on extending Y Combinator’s reach and scope, positioning the firm to capitalize on the next wave of entrepreneurial innovation. In diversifying Y Combinator’s portfolio to include some of the most innovative ideas across verticals like energy, artificial intelligence, robotics, human augmentation, and virtual reality, Altman is driving efforts to push VCs to act differently. In conversation with Adriana Cisneros, CEO and Vice Chairman of Cisneros, we will hear what drives Sam, what keeps him up at night, how Y Combinator decides which moonshot ideas to fund and support, how the accelerator defines entrepreneurial ecosystems, and what it takes to build the next unicorn.
