All of this largely pales in comparison to his work at OpenAI since 2019. OpenAI was co-founded in 2015 by Greg Brockman, Ilya Sutskever, Trevor Blackwell, Vicki Cheung, Andrej Karpathy, Durk Kingma, Jessica Livingston, John Schulman, Pamela Vagata, and Wojciech Zaremba, with Altman as Chief Executive Officer. Since then, the artificial intelligence research firm rose to a valuation of roughly $80 billion during 2023 — a valuation which currently hangs in the balance now that Altman has been ousted, followed by former President of OpenAI Greg Brockman, and (most likely) over 700 of the 770-strong workforce.
