Summary
OpenAI split its organization in two, with Simo overseeing much of the company’s core business while CEO Sam Altman focuses on research and compute. It’s a remarkable remit for any executive, and becomes all the more so when you learn more about what Simo has been navigating at the same time. Simo has long discussed women’s health, including while she was CEO of Instacart and a Facebook exec. In 2021, she launched an organization called the Metrodora Institute that was built to better integrate care for patients with neuroimmune disorders, especially women. Simo’s news wasn’t the only unfortunate update for OpenAI’s executive team. OpenAI CMO Kate Rouch is stepping down to focus on her recovery from breast cancer; she was diagnosed shortly before she stepped into the job.
