OpenAI's Greg Brockman says the company's staff exits are not unusual. Here is what happened.

Key points

• OpenAI revenue chief Denise Dresser left the company in May 2026 after just eight months in the role.
• Chief operating officer Brad Lightcap also departed after eight years at OpenAI, two days before Dresser's exit.
• OpenAI named Dali Rajic, former COO of cybersecurity firm Wiz, as its new chief revenue officer.
• President Greg Brockman told CNBC's Squawk Box the rate of turnover is "not actually that atypical" for a company of OpenAI's size.

Two senior OpenAI executives walked out the door within two days of each other last week. From the outside, it looked like a crisis. Greg Brockman, OpenAI's president and co-founder, says it is not.

"I actually think that the difference between OpenAI and other organizations is that we are so much in the spotlight, so every departure gets scrutinized in a way that it doesn't otherwise," Brockman said in an interview with CNBC's Squawk Box on Monday.

What exactly happened?

Denise Dresser, who joined OpenAI as its chief revenue officer in late 2024, left suddenly after eight months. She had been brought in to grow the company's enterprise business, the division that sells AI tools directly to large organisations, and was considered central to competing with Anthropic, OpenAI's main rival.

Her exit came just 48 hours after Brad Lightcap announced he was leaving. Lightcap had spent eight years at the company and served as its operating chief before being moved in April to a vague "special projects" role. He said he was leaving to "start something new."

OpenAI's replacement for Dresser is Dali Rajic, the former chief operating officer of Wiz, a cybersecurity company that Google bought for $32 billion earlier this year.

Should anyone be worried?

Brockman does not think so, and he pointed to two factors. First, OpenAI attracts far more press attention than most companies its age, meaning each departure is reported rather than absorbed quietly. Second, he described himself and chief executive Sam Altman as the constants that hold the company's direction stable while leadership around them changes.

"There have been different eras where we have different sets of leaders in place," Brockman said. "I'm a constant, Sam is a constant, and I think that we are stronger because of that resilience and diversity."

At a meeting with investors on Friday, first reported by CNBC, Brockman thanked Dresser for building what he called the company's "enterprise foundation" and expressed enthusiasm about Rajic stepping in.

What does this mean for people who use OpenAI products?

For now, nothing changes day to day. ChatGPT still works the same way. The leadership shifts sit inside the sales and commercial side of the business, not the engineering teams building the products most people use.

The enterprise push does matter long-term. OpenAI is trying to sign large contracts with hospitals, law firms and corporations, competing directly with Anthropic for that business. Whether Rajic, who helped Wiz scale rapidly before its acquisition, can keep that momentum going is a fair question. His record suggests he can, but OpenAI has not yet disclosed any targets or timelines.

Brockman's reassurance is a company line, and it is worth noting that context. Even so, two constants at the top of a 2,000-person organisation is more stability than many fast-growing AI companies can claim.
