Denise Dresser spent eight months as OpenAI's chief revenue officer. On Thursday, Aug 13 2026, the company said she is leaving to pursue other interests.
Dresser joined in December after more than a decade in executive roles at Salesforce. Her job was to win enterprise clients, the corporate customers who buy AI tools in bulk.
In April, she took over many of the duties Brad Lightcap handled before he moved to a special-projects role.
In a LinkedIn post, Dresser called the work "nothing short of incredible" and said she was proud of what the team accomplished. She also wrote that "no one works harder than this team" and that she was deeply grateful to everyone she worked with.
She will stay for a brief transition period, coordinating with Dali Rajic on the handover. Her replacement is Dali Rajic, previously president and COO of the cybersecurity firm Wiz.
Brad Lightcap, who spent eight years at OpenAI and was close to Sam Altman personally and professionally, said Tuesday on X that he was leaving to "start something new."

Lightcap's exit is notable on its own terms. He was one of the longest-tenured leaders at the company and a trusted figure in Altman's inner circle.
The turnover goes deeper. Fidji Simo, OpenAI's former product and business chief, announced a month ago that she would step back to focus on healing from a "severe exacerbation of a chronic illness." Three more executives left in April.
That pattern matters because of what is coming next. In June, OpenAI confidentially filed its IPO paperwork with the SEC, and Anthropic had taken that step only a few days earlier.
The company wrapped up a March funding round at an $852 billion valuation. It has to defend that number to public investors, and a leadership shake-up does not make that job easier.
The revenue chief's departure is especially complicated because of what she was hired to do. OpenAI needs her enterprise expertise to counter Anthropic, its closest rival in selling AI to businesses.
That competition is heating up. In January, CFO Sarah Friar told CNBC that enterprise clients made up roughly 40% of the company's business, with the share expected to approach 50% by year-end. Dresser said in April that the effort was "on track."
The departure of the person steering that push is not ideal timing. But the company is not standing still. Rajic comes from Wiz, a fast-growing cybersecurity firm, and Dresser will stay long enough to help customers through the change.
Corporate customers are the ones who pay for AI tools at scale, month after month. That steady money is a big part of what makes a company like OpenAI worth $852 billion in the first place.
OpenAI is heading toward a public debut with a fresh leadership team and a very high price tag. Investors will want proof the company can keep growing, and the next few months of enterprise results will show whether the shake-up is a blip or a problem.
Going public means opening the books to scrutiny that private companies never face. Leadership changes that might pass quietly at a private firm become headlines when an IPO is on the table.
The enterprise business is the clearest window into that. It is the part of OpenAI that brings in steady, repeatable revenue, and it is where the company is fighting hardest to win corporate customers. If that engine keeps humming through the leadership changes, the IPO story stays intact. If it sputters, the $852 billion valuation gets harder to justify.
