OpenAI Chief Revenue Officer Denise Dresser is leaving less than a year after joining the artificial intelligence company, CNBC reported Thursday, citing an OpenAI release. The company said Dresser is departing “to pursue other opportunities,” according to CNBC. OpenAI has hired Dali Rajic to replace her, CNBC reports. Rajic previously served as president and chief operating officer of Wiz, the cybersecurity company. Dresser joined OpenAI in December after more than a decade at Salesforce, according to CNBC. In 2023, she was named chief executive of Slack, the workplace messaging company Salesforce acquired for more than $27 billion in 2020. The move marks the second senior OpenAI departure in days. CNBC reports that longtime OpenAI executive Brad Lightcap said Tuesday on X that he is leaving the company to “start something new.” The timing matters because CNBC says OpenAI is preparing for what is expected to be a blockbuster initial public offering. A revenue chief change at that stage puts added attention on the company’s commercial leadership, even with a replacement already named. This remains a developing story. CNBC described the report as breaking news and said updates may follow, so the available record is limited to the company-attributed announcement and the personnel details reported so far. Who benefits: Dali Rajic steps into one of OpenAI’s most commercially important roles. Customers, partners and prospective public-market investors at least have a named revenue leader to evaluate rather than an open position. Who's exposed: OpenAI is exposed to questions about senior leadership turnover after two departures in a matter of days. Dresser’s exit is especially visible because CNBC frames it against the company’s IPO preparations.
