- Denise Dresser announced her departure on Thursday, less than a year after joining OpenAI as chief revenue officer from Slack in December to lead the enterprise unit.
- Brad Lightcap ended his eight-year OpenAI stint days earlier to 'start something new,' following Fidji Simo's July exit and the April departures of VP of Science Kevin Weil and marketing chief Kate Rouch.
- Dali Rajic, former COO of cybersecurity firm Wiz (acquired by Google for $32 billion), was named OpenAI's new chief revenue officer, introduced to the company through Thrive Capital founder Josh Kushner.
- AI startup founder Kevin McCormick called the executive exodus a 'huge red flag' ahead of OpenAI's confidential IPO filing in June at an $852 billion valuation.
- Greg Brockman told employees run-rate revenue grew more than 20% month-over-month in July, with 32% growth in business customers and the enterprise unit doubling to 2 million customers year-over-year.
- Sarah Friar told investors at a Friday meeting that enterprise now generates more revenue than the ChatGPT-led consumer business, a milestone Dresser had projected for end of 2026.
Why it matters: The departures deepen pressure on Altman and Brockman to project stability to investors already worried about Google and Anthropic competition, lower-cost open-weight models, and SpaceX's volatile post-IPO performance — yet Brockman simultaneously touted 20%+ monthly revenue growth and an enterprise unit that already outearns consumer ChatGPT, forcing backers to weigh governance risk against surging fundamentals.
