OpenAI No. 2 Executive Resigns, Fidji Simo Hired as Part-Time Consultant After Health Setback
On July 10, Fidji Simo, OpenAI's second-highest-ranking executive, announced she would step down from her full-time role. In an internal letter to employees on Thursday local time, Simo explained she had taken a leave of absence due to a recurrence of her neuroimmune system disease. However, her recovery has been slower than anticipated, prompting her to shift to a part-time consulting role.
Simo joined OpenAI's board in 2024 and became CEO of the company's applications division in May 2025. This role was created to unify the company's business and product operations. At that time, several executives—including Chief Operating Officer Brad Lightcap, Chief Financial Officer Sarah Friar, and Chief Product Officer Kevin Weil—reported to her, while CEO Sam Altman focused more on research, computing power, and security. Before joining OpenAI, Simo had been CEO of Instacart since 2021, leading the company through its IPO in 2023. She previously spent over a decade at Meta, overseeing core Facebook app operations.
As ChatGPT Growth Slows, OpenAI Faces Dual Pressures
This leadership change has significant implications for OpenAI. Simo was primarily responsible for driving the company's consumer business growth. With ChatGPT's growth slowing late last year and falling short of internal revenue targets, OpenAI now faces pressure to adjust its business strategy, including a shift toward more competitive programming tools.
As OpenAI prepares for a potential IPO and competes fiercely with rival Anthropic in the enterprise market, Simo's departure places urgent pressure on Altman to find a successor. Losing the "number two" executive during this critical phase of commercial expansion and IPO preparation undoubtedly increases uncertainty in the company's strategic execution.
With Frequent Executive Departures, OpenAI Strengthens Talent Strategies
OpenAI has undergone frequent personnel restructuring in recent years. Earlier this year, the company saw the departures of Chief Marketing Officer Kate Rouch and Chief Product Officer Kevin Weil. The current executive team includes Sam Altman, Brad Lightcap, Sarah Friar, and co-founder Greg Brockman. Analysts suggest that current Chief Revenue Officer Denise Dresser may take on additional responsibilities.
