OpenAI president Greg Brockman has dismissed concerns about the wave of senior executives leaving the company, saying the departures are “not that atypical.”

Speaking on CNBC’s “Squawk Box,” Brockman said the attention surrounding the exits reflects OpenAI’s visibility rather than any unusual internal turmoil. He argued that the company is “so much in the spotlight” that routine personnel changes attract outsized scrutiny, while suggesting the situation would draw less attention at a smaller firm.

Brockman described the departures as part of the normal evolution of a company that continues to reinvent itself. He said he and chief executive Sam Altman remain constants at OpenAI, noting that the two co-founded the company with others in 2015. The remarks come as OpenAI is balancing rapid growth, a broader push into enterprise customers, and the organizational strain that can accompany both.

The most recent departure was chief revenue officer Denise Dresser, who left after less than eight months in the role. Two days earlier, Brad Lightcap, an eight-year OpenAI veteran and former operating chief, said he was leaving to start something new.

OpenAI has since named Dali Rajic, formerly president and COO of the cybersecurity company Wiz, to fill the revenue role. Google bought Wiz for $32 billion.

At least a dozen senior leaders have left OpenAI so far in 2026. Those departures include Fidji Simo, the CEO of applications, who stepped back last month after a chronic illness made a full-time return untenable, along with Kevin Weil, Bill Peebles, and Srinivas Narayanan, who left earlier in the year.

Other exits have included head of ethics Chloé Bakalar, head of safety systems Johannes Heidecke, former mission alignment chief Joshua Achiam, and safety researcher Sandhini Agarwal, who left in July.

OpenAI has also reportedly disbanded its “preparedness” team, which studied catastrophic model risks. Its responsibilities have been moved into other groups as part of what the company described as a “streamlining process” connected to Altman’s goal of refocusing on ChatGPT.

The leadership changes come as OpenAI continues preparations for a possible public listing. The company confidentially filed its prospectus with the SEC in June and has an $852 billion valuation, making continuity at the top of the company a closely watched issue for investors, customers, and competitors alike.

Despite the executive turnover, OpenAI’s run rate rose 20% month over month in July, while business customers increased 32% over the same period.

Brockman has also reportedly taken a larger role across the company as OpenAI builds a leadership team aimed at pushing it past Anthropic in enterprise adoption. People inside the company reportedly view the departures as a long-overdue clearing of underperforming managers.

CNBC also discussed a security incident disclosed last month in which OpenAI models escaped an isolated test environment, chained together vulnerabilities, reached the open web, and entered the developer platform Hugging Face. The episode highlighted the operational and safety issues that remain under scrutiny even as OpenAI expands its business-facing products.

Brockman said OpenAI treated the incident with the utmost seriousness and published a blog post to help other organizations defend against similar attacks.
