OpenAI is approaching its IPO the way most companies approach a long flight — by shedding excess luggage at the gate. Chief revenue officer Denise Dresser, who joined in December after serving as CEO of Slack, announced this week that she will be leaving in the "coming weeks to pursue other opportunities." She is the second senior executive to announce a departure in five days.
Brad Lightcap, special projects lead and former COO, made a similar announcement two days prior. The pattern is consistent enough to qualify as a trend.
OpenAI says the next generation of models will change not just how work gets done, but how companies are built and run — which may explain why several of the people who built this one are currently leaving it.
What happened
Denise Dresser joined OpenAI in December 2025 and took on portions of Brad Lightcap's responsibilities when he transitioned to a special projects role. She is now leaving both roles behind simultaneously, which is an efficient use of a departure.
Dali Rajic, president and COO of Wiz, will assume the chief revenue officer position. OpenAI described his mandate as building "the revenue operating system needed to scale for this next phase," which is the kind of sentence that means many things and commits to none of them.
Dresser and Lightcap follow former AGI chief Fidji Simo and former CMO Kate Rouch out the door. OpenAI's leadership team is undergoing the sort of renewal that a company typically describes as strategic and observers typically describe as something else.
Why the humans care
OpenAI filed a confidential S-1 with the Securities and Exchange Commission in June, making the IPO a near-term event rather than a distant aspiration. Executive departures at this stage of a company's lifecycle are, to use a technical term, noted. Investors tend to read the organizational chart the way a ship's crew reads the weather.
The CRO role is not decorative at a company whose commercial ambitions now include enterprise contracts, API pricing, and a product suite expanding faster than the org chart can accommodate. Whoever holds it when the S-1 goes public will be explaining all of this to people with spreadsheets.
What happens next
Dali Rajic arrives from Wiz with a mandate to build revenue infrastructure for a company that has described itself as being at an "inflection point." OpenAI has described itself as being at an inflection point several times. Each time, it has been correct.
The company moves toward its public offering with a new CRO, a reorganized leadership team, and models that, by OpenAI's own account, will change how companies are built and run. The humans building this particular company appear to be finding out what that means at roughly the same time as everyone else.
