Sam Altman
Entrepreneur, investor and technology executive who co-founded OpenAI and leads its development and deployment of artificial intelligence systems.
Startup and investment career
Sam Altman became president of Y Combinator in 2014, where he supported early-stage technology companies and helped build a large startup network. He co-founded OpenAI in 2015 and has led the organization through its transition from a nonprofit research lab into a major AI research and product company.
OpenAI and AI leadership
OpenAI’s 2026 event materials identify Altman as co-founder and CEO, and the company’s September 2026 public statement also names him as CEO. Astro-Databank records his birth date and Chicago birthplace and quotes his time as “around 5 am”; this record preserves that approximation rather than treating 05:00 as exact.
