Bio:
Born on April 22, 1985, in Chicago, Illinois, Sam Altman grew up in St. Louis, Missouri, in a middle-class Jewish family. His early passion for technology was sparked when he received his first computer, an Apple Macintosh LC II, at the age of eight. Altman attended John Burroughs School and later enrolled at Stanford University to study computer science. However, he dropped out in 2005 after two years to pursue entrepreneurial ventures.
Altman’s first major venture was Loopt, a mobile social networking service that raised over $30 million in venture capital before being acquired by Green Dot Corporation in 2012. He joined Y Combinator as a partner in 2011 and became its president in 2014. Under his leadership, Y Combinator scaled significantly, reviewing over 40,000 startup applications annually.
In 2015, Altman co-founded OpenAI with Elon Musk and others to advance artificial intelligence research while ensuring its safety and benefits for humanity. He became CEO in 2019 after OpenAI transitioned into a “capped-profit” corporation. Under his leadership, OpenAI launched groundbreaking projects like ChatGPT (2022) and DALL.E (2023), which have revolutionized text generation and digital image creation.
Altman briefly faced dismissal as OpenAI CEO in November 2023 but was reinstated after widespread support from employees and investors. In addition to his work at OpenAI, Altman is involved in clean energy initiatives through Helion Energy (nuclear fusion) and Oklo Inc. (advanced fission reactors).
