Another senior executive is departing OpenAI. Denise Dresser, who joined as chief revenue officer in December after serving as CEO of Slack, said in a team note posted to LinkedIn that she will leave in the "coming weeks" to "pursue other opportunities."

According to OpenAI, Dali Rajic, president and COO of Wiz, will take over the role.

Four names in a short span

Dresser's departure is the latest in a string of major exits:

  • Denise Dresser — chief revenue officer, joined in December
  • Brad Lightcap — special projects lead and former COO; announced his exit two days earlier
  • Fidji Simo — former AGI chief, recently stepped down
  • Kate Rouch — former CMO, recently stepped down

The connection is notable too: when Lightcap moved to the special projects role, Dresser had taken over some of his work. Now both are leaving.

The company's framing

OpenAI presents the change as an inflection: "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. Dali will build the revenue operating system needed to scale for this next phase."

The timing

The most striking aspect of these exits is not what they are but when they happen. Dresser is leaving 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.

Senior leadership changing at this pace inside a company preparing to list is not routine. For investors, continuity in the management team is a factor that bears directly on valuation — in Anthropic's own pre-listing investor conversations, the management team was reportedly one of the agenda items.

With two major labs preparing to go public in the same period, how departures like these are read will be discussed a good deal more in the coming months.

Why it draws attention

Senior departures are not unusual on their own; role changes are expected at a fast-growing company. What stands out is that four of them fall into a short window and all come from the commercial side: revenue, operations, marketing and product strategy.

That is a different pattern from departures on the research side. Researcher exits are usually explained by disagreements over direction; commercial leadership exits more often concern structure itself — who decides what, and which function reports where.

OpenAI's phrase "revenue operating system" hints at the same thing: what is being built is not a new team but a new arrangement.

One more detail worth noting is where the replacements come from. Dresser arrived from Slack; Dali Rajic, who takes over, comes from the cloud security company Wiz. That suggests OpenAI is recruiting its commercial bench not from the AI sector but from the established players of enterprise software — an expected choice for a company preparing to list.
