Personal Details
Childhood and Schooling
Sam Altman was born in Chicago, Illinois, on April 22, 1985, and was raised in St. Louis, Missouri. Connie Gibstine, his mother, works as a dermatologist. After getting his first computer, an Apple Macintosh, when he was eight years old, Altman became interested in technology at an early age and learned how to write and disassemble computer hardware. After attending the John Burroughs School in Ladue, Missouri, he went on to Stanford University to study computer science but left after just two years to focus on his business endeavors.
Motivators & Impacts
Altman’s early exposure to computers and the emerging tech sector shaped his love of technology and business. His engagement with Y Combinator further influenced his dedication to promoting innovation and his investment strategy.
Beginnings as an Entrepreneur: Loopt
Together with two other Stanford students, Altman co-founded Loopt, a location-based social networking mobile application, in 2005 when he was just 19 years old. Loopt used GPS technology to give users information about friends who live nearby and local landmarks. The business attracted a lot of interest and raised more than $30 million in venture money. Loopt was finally purchased by Green Dot Corporation in 2012 for $43.4 million after failing to gain widespread adoption despite its early promise.

Co-Founding OpenAI
Alongside prominent individuals like Elon Musk, Jessica Livingston, and Peter Thiel, Altman co-founded OpenAI, an artificial intelligence research organization, in December 2015. The goal of OpenAI was to guarantee that artificial general intelligence (AGI) will be advantageous to all people. Initially set up as a charity, the group secured $1 billion in promises from its founders and other investors, such as Amazon Web Services and Microsoft. Altman was a member of OpenAI’s board of directors and was instrumental in setting the company’s strategic course.
Change to CEO of OpenAI
In order to concentrate on OpenAI, Altman left his daily duties at Y Combinator in 2019 and assumed the position of CEO. He oversaw OpenAI’s shift from a charity to a “capped-profit” business model, which enabled it to draw in investment while upholding its dedication to helping people. Important collaborations were made possible by this reorganization, most notably Microsoft’s $1 billion 2019 investment in OpenAI. Notable developments in AI research have occurred during Altman’s time as CEO, including the creation and publication of models like GPT-3 and the AI chatbot ChatGPT, whose capabilities have drawn attention from all over the world.
