OpenAI’s Fidji Simo Transitions to Advisory Role Due to Chronic Illness

OpenAI’s second-ranking executive, Fidji Simo, is leaving her full-time role as CEO of AGI Deployment and transitioning to a part-time advisory position after an extended medical leave caused by a severe worsening of her chronic neuroimmune condition, Postural Orthostatic Tachycardia Syndrome (POTS). Diagnosed with POTS in 2019, Simo stepped away from the company in April to focus on recovery, noting that her journey to health would be longer and more complex than anticipated. President Greg Brockman has assumed product responsibilities during her absence, and her departure creates a leadership gap at OpenAI ahead of a potential IPO. The move underscores the personal health challenges facing top tech leaders and signals a shift in OpenAI’s strategic execution as it advances toward deploying artificial general intelligence.
