Brad Lightcap, who spent eight years at OpenAI and rose to chief operating officer, is leaving the company to start a new venture. The departure, confirmed this week, adds to a year of senior exits at the AI firm.
A long run building OpenAI's business
Lightcap joined OpenAI in 2018, when the company was still a research lab with a fraction of its current footprint. He helped build the finance, legal, and business teams that would later support products like ChatGPT. He became COO in 2024, then moved into a special projects role in April of this year.
Denise Dresser, the company's chief revenue officer, has taken over some of the responsibilities Lightcap previously handled. The transition appears to have been in motion for months.
Parting words from both sides
Sam Altman, OpenAI's CEO, thanked Lightcap and said he looked forward to working together on what's next. Lightcap said he would remain for a few weeks to help with the handoff. He expressed gratitude and said the mission success feels within sight.
Neither side gave details about the new venture. Lightcap's next move is still under wraps.
A year of senior exits
Lightcap is not the only high-profile departure this year. Fidji Simo, Chloé Bakalar, Bill Peebles, Kevin Weil, and Srinivas Narayanan have all left. Those exits followed the shutdown of Sora, OpenAI's video generation app.
Earlier departures included Hannah Wong, Kate Rouch, and Caitlin Kalinowski, who joined rival Anthropic. The pattern has raised questions inside the company about leadership stability, though OpenAI has continued to hire aggressively.
IPO paperwork in the background
OpenAI submitted a confidential S-1 registration statement to the SEC in June, a step toward a potential public offering. The company has not commented on timing. Lightcap's exit comes as OpenAI works through that process and reshuffles its executive ranks.
He'll stay on for a few weeks, then hand off fully. The S-1 remains under SEC review, and OpenAI has not set a date for its debut.
