SAN FRANCISCO — Brad Lightcap, a longtime OpenAI executive who built the company's enterprise sales operation, announced his departure Tuesday in the latest leadership change at the artificial intelligence company.
Lightcap joined OpenAI in 2018 and served as its chief operating officer for four years. In April, he shifted to special projects, with Chief Revenue Officer Denise Dresser absorbing most of his responsibilities. In a post on X, he said he was leaving to start something new, adding that he felt fortunate to have spent most of the last decade pursuing the company's mission and that success feels within sight.
CEO Sam Altman responded on X, saying he fondly remembered their earliest conversations about OpenAI. Lightcap was one of the few who understood the vision from the start, Altman said, and OpenAI would not be where it is without him.
The timing is awkward for a company trying to command an $852 billion valuation. Lightcap was central to OpenAI's push into the enterprise market, growing the go-to-market team from roughly 50 people to more than 700 over an 18-month stretch through mid-2025. That expansion covered sales, customer success, developer relations and strategic partnerships.
The effort accelerated in 2023 alongside the releases of GPT-4 and ChatGPT Enterprise, as OpenAI worked to convert consumer momentum into recurring business revenue and compete directly with Anthropic. Lightcap told CNBC about a year ago that enterprise clients began arriving from every direction.
His exit follows a run of senior departures. Last month, Fidji Simo, who led product and business, stepped down citing a severe exacerbation of a chronic illness. Three executives left in April: Bill Peebles, who led the discontinued Sora short-form video app; Kevin Weil, vice president for science; and Srinivas Narayanan, technology chief of B2B applications.
In his X post, Lightc he found it rewarding to watch the teams mature under capable leaders and said he is excited for the next decade in their hands.
