OpenAI has made another senior leadership change as it moves toward an IPO. According to TechCrunch and Axios, chief revenue officer Denise Dresser is leaving the company less than a year after taking the role, with former Wiz president and chief operating officer Dali Rajic set to replace her. Dresser, a former Slack executive, spent about nine months in the post after joining OpenAI last year. Rajic comes from Wiz, the cloud security company that was acquired by Google in 2026 for $32 billion.
The move marks OpenAI’s second executive departure in a matter of days and its third major leadership change in roughly six months. Brad Lightcap, who had served as chief operating officer, recently said he was leaving to pursue 「something new」. Earlier, in July, Fidji Simo, described in the report as the company’s No. 2 executive responsible for AGI deployment, also departed, with president Brockman taking on broader management responsibilities.
These changes are unfolding after OpenAI confidentially filed with the U.S. Securities and Exchange Commission for what could become one of the largest tech IPOs in history. The company reportedly has more than 1 billion weekly active users and 2 million enterprise customers.
OpenAI is reshuffling its leadership again as it pushes toward an IPO. According to TechCrunch and Axios, chief revenue officer Denise Dresser is leaving the company less than a year after taking the job, and former Wiz president and chief operating officer Dali Rajic will take over.
Dresser leaves after about nine months in the role
Dresser, a former Slack executive, joined OpenAI last year as CRO. The report said her tenure lasted about nine months.
Rajic, who is stepping in, previously served as president and COO of Wiz. The report noted that Wiz was acquired by Google in 2026 for $32 billion.
OpenAI president Brockman said that as the company’s product deployment model changes, Rajic will turn what the company has learned into 「repeatable execution」.
Second executive exit in days, third senior change in six months
The departure is OpenAI’s second senior executive loss within days. A few days earlier, longtime COO Brad Lightcap also said he was leaving, saying he wanted to pursue 「something new」.
Earlier still, in July, Fidji Simo, described in the report as the company’s No. 2 executive and the leader responsible for AGI deployment, had already exited. Brockman then took on broader management duties.
Leadership changes land as OpenAI prepares for IPO
The management turnover comes after OpenAI confidentially filed with the U.S. Securities and Exchange Commission, or SEC, for what the report described as one of the biggest technology IPOs in history. OpenAI currently has more than 1 billion weekly active users and 2 million enterprise customers, according to the report.
For a company preparing to go public while still expanding quickly, the frequent turnover at the top is likely to draw attention to governance.
