OpenAI's Denise Dresser departs, second exec exit this week

Denise Dresser, OpenAI's chief revenue officer since December, is leaving the company. In a team note posted to LinkedIn, she said she would depart in the "coming weeks" to "pursue other opportunities." Dresser joined OpenAI as CRO after previously serving as CEO of Slack. Dali Rajic, president and COO of Wiz, will take over the CRO role, according to OpenAI.
Dresser's announcement makes her the second OpenAI executive to say this week that they are leaving. Two days earlier, special projects lead and former COO Brad Lightcap said he would depart; Dresser had taken over part of Lightcap's work when he moved into the special projects role. Her exit follows other recent senior departures: former AGI chief Fidji Simo and former CMO Kate Rouch have also stepped down, extending a string of major exits from the company.
In a statement, OpenAI framed the change around its next generation of models: "We're now at an inflection point: the next generation of models will change not just how work gets done but how companies are built and run," the company said, adding that "Dali will build the revenue operating system needed to scale for this next phase."
Dresser's departure also comes ahead of OpenAI's IPO. The company announced in June that it had submitted a confidential S-1 filing to the Securities and Exchange Commission, though it has not given a date or timeline for the offering.
Key facts
- Denise Dresser, OpenAI's chief revenue officer since December and previously CEO of Slack, is leaving in the "coming weeks" to "pursue other opportunities."
- Dali Rajic, president and COO of Wiz, will take over as OpenAI's CRO.
- Dresser is the second OpenAI executive to announce a departure this week, after special projects lead and former COO Brad Lightcap said two days earlier that he would leave.
- Former AGI chief Fidji Simo and former CMO Kate Rouch have also recently stepped down from OpenAI.
- Dresser's exit comes ahead of OpenAI's IPO; the company announced in June that it had submitted a confidential S-1 filing to the SEC.
Why it matters
Dresser's departure is the latest in a string of senior exits at OpenAI: former AGI chief Fidji Simo, former CMO Kate Rouch, and special projects lead and former COO Brad Lightcap have all left or announced departures recently, with Lightcap's announcement landing just two days before Dresser's. The reshuffle at the top is happening while OpenAI works toward going public: the company announced in June that it had submitted a confidential S-1 filing to the SEC, and Dresser's exit lands ahead of that process.
Who it affects
Most directly, OpenAI's revenue organization, which passes from Dresser to Dali Rajic, joining from Wiz where he was president and COO. In its statement, OpenAI said Rajic will "build the revenue operating system needed to scale for this next phase," tying the appointment to what it calls an inflection point in how new models change the way companies are built and run. Beyond that handover, the reshuffle is visible to OpenAI's employees, partners and anyone tracking its leadership bench as the company works toward a public listing.
How to use it
There is no product or service here, but the timeline matters for anyone dealing with OpenAI commercially. Dresser said she is leaving in the "coming weeks," so the handoff is not immediate. Rajic then takes over as CRO, but the source does not say when he starts at OpenAI or whether he is also leaving his post at Wiz, so no hard transition date is public yet.
How solid is it
Dresser's departure comes from her own note, posted to LinkedIn, about as direct as sourcing gets for a personnel story. OpenAI's quotes on the handover, including the line that Rajic will "build the revenue operating system needed to scale for this next phase," are attributed to the company as a whole rather than to a named spokesperson. The framing of this as part of a broader pattern, following Simo, Rouch and Lightcap, is the report's own characterization rather than a claim OpenAI itself makes.
Risks and caveats
Several basic facts are missing so far. Neither "December," when Dresser joined, nor "June," when OpenAI announced its confidential SEC filing, carries a year in the source. No reason is given for her departure beyond the stated intent to "pursue other opportunities"; there is no mention of conflict or being pushed out. Simo's and Rouch's exits are dated only to "recently," with no specific day given, and a confidential S-1 filing is not a confirmed IPO: OpenAI has not stated a date, a timeline, or confirmed the offering will go ahead.
