- Denise Dresser resigned as OpenAI's CRO on Thursday, two days after Brad Lightcap ended his eight-year stint—marking the latest in a string of C-suite exits that also included Fidji Simo's July departure to focus on a chronic illness.
- OpenAI named Dali Rajic, former COO of cybersecurity firm Wiz (which Google acquired for $32 billion earlier this year), as Dresser's replacement; Rajic was introduced to the company through Thrive Capital founder Josh Kushner.
- Under Dresser, OpenAI's enterprise business grew to 2 million customers—doubling year-over-year—and CFO Sarah Friar told investors enterprise now generates more revenue than the ChatGPT-led consumer business.
- President Greg Brockman told employees July run-rate revenue grew more than 20% month over month, including 32% growth in business customers, and said the company is at an 'inflection point' for its next-generation models.
- OpenAI confidentially filed its IPO prospectus in June at an $852 billion valuation, but has provided no timeline for the offering as investors grow wary of competition from Google and Anthropic and lower-cost open-weight models.
- Kevin McCormick, founder of AI startup SignAudit.AI, called the executive exodus a 'huge red flag' for the IPO on X, noting Dresser likely walked away from a large pay package after less than a year.
- Sam Altman made no public X post about Dresser's departure—unlike his tribute to Lightcap—and his only Thursday activity on the platform was responding to OpenAI's preview of 'Ultrafast mode' GPT-5.6.
Why it matters: For investors eyeing OpenAI's IPO at an $852 billion valuation, the back-to-back exits of Dresser and Lightcap—and Altman's silence on Dresser's departure—put a spotlight on the leadership gap behind the enterprise growth story. With enterprise now its largest revenue stream, the architect of that 2 million-customer base is gone.
