Brad Lightcap, OpenAI's former CFO and COO, leaves after eight years. His exit follows Fidji Simo, Johannes Heidecke, and others as the company restructures ahead of a potential IPO.
Brad Lightcap, one of OpenAI's longest-serving executives, told the company Tuesday he is leaving to start something new. The departure is the latest in a string of exits at the AI company as it pushes toward an initial public offering.
Lightcap served as chief financial officer and chief operating officer over eight years and most recently led a special projects team. He posted a goodbye message on X calling the decision bittersweet and said he would keep supporting OpenAI's mission from a different vantage point. He gave no details on his next move. Lightcap said he would stay available to staff for a few more weeks.
OpenAI declined to comment beyond pointing to his post. Lightcap did not respond to requests for comment.
His exit comes a month after Fidji Simo, another senior OpenAI executive, moved into an advisory role. Johannes Heidecke, the company's head of safety systems, left in July. Other recent departures include AI ethics lead Chloé Bakalar and chief futurist Joshua Achiam, the Financial Times reported.
Lightcap moved to the special projects role in April. An internal memo at the time said he would report to CEO Sam Altman and work to expand OpenAI's enterprise software sales through private equity partnerships. Denise Dresser, then the new chief revenue officer, took on some of his commercial duties.
Before joining OpenAI in 2018, Lightcap invested at Y Combinator, worked on strategic finance at Dropbox, and started his career as an investment banking analyst at J.P. Morgan.
The departures come as OpenAI restructures its leadership ahead of a potential IPO. The company has been shifting its focus from research to commercial operations, a transition that has prompted several top executives to leave over the past year.
Lightcap's departure removes a key figure who helped build OpenAI's financial and operational infrastructure from its early days. His eight-year tenure spanned the company's transformation from a nonprofit research lab to a for-profit company valued at $80 billion.
