Denise Dresser's time in the Chief Revenue Officer seat at OpenAI adds up to less than a year — about nine months. That number alone is the story: at a company gearing up for one of the biggest tech IPOs in history, the person running revenue is turning over faster than most public companies' earnings cycles.
Her successor is Dali Rajic, former President and COO of Wiz. The name Wiz now comes with its own footnote — the company was acquired by Google for $32 billion in 2026, and Rajic is walking straight out of that deal. What he's stepping into now is a company in an unusually sensitive, unusually busy stretch.
Dresser's exit isn't an isolated case. Within days, OpenAI COO Brad Lightcap is also set to leave — the second executive departure in the same stretch. Pull the timeline back further and Fidji Simo already left in July — the third in half a year. Three people, three points in time, and stacked together, the density speaks for itself.
All of this is happening as OpenAI quietly files for what could be one of the biggest tech IPOs in history. Executive turnover happens at any company, but placed against the backdrop of an IPO countdown, the timing becomes the part most worth watching — the source material offers no further explanation, and none needs to be added.
