OpenAI revenue chief quits after less than a year

August 13, 2026 1:59 PM EDT

Investing.com -- OpenAI announced Thursday that Chief Revenue Officer Denise Dresser is leaving the artificial intelligence company less than a year after joining, marking another senior departure as the firm prepares for its initial public offering.

The company said Dresser is leaving "to pursue other opportunities." OpenAI hired Dali Rajic, former president and chief operating officer of cybersecurity firm Wiz, as her replacement.

"The opportunity to work hands-on with the most transformative technology in the world has been nothing short of incredible," Dresser wrote in a LinkedIn post Thursday. "I am so proud of what we have accomplished and, even more, of how this team has shown up for our customers and one another."

Dresser joined OpenAI in December after spending more than a decade as an executive at Salesforce. She took over many responsibilities from Brad Lightcap in April when he moved to a role focused on special projects.

Lightcap announced his departure Tuesday, stating on X that he plans to "start something new." He spent eight years at OpenAI and worked closely with CEO Sam Altman.

Fidji Simo, OpenAI's product and business chief, stepped down last month to focus on recovery from a severe exacerbation of a chronic illness. Three additional executives left the company in April.

The departures occur as OpenAI prepares for its public market debut. The company filed its IPO prospectus with the Securities and Exchange Commission confidentially in June. OpenAI completed a funding round in March at an $852 billion valuation.
