Brad Lightcap, OpenAI's special projects lead and former COO, is calling it quits after eight years at the AI lab. In an internal memo - later posted to X for posterity - Lightcap told colleagues he's starting "something new," which is corporate-speak for "I have no idea what I'm doing next either."

"Over the last few months, I've been focused on the next horizon and what would stand in the way of mission success," Lightcap wrote, presumably while gazing thoughtfully at a whiteboard. "I believe there are a few important new things the world will need to get right as we enter this next period. I … am excited to help you all advance the mission from a different vantage point." He added he'll stick around for a few more weeks, because even visionaries need to clean out their desks.

Lightcap's role has been a game of musical chairs over the past year and a half. In March 2025, his COO gig expanded to include overseeing "business and day-to-day operations," global deployment, business strategy, key partnerships, infrastructure, and "operational excellence" - a phrase that sounds important but means nothing. Then in January 2026, he stepped back from leading enterprise product and engineering but kept the commercial reins. (Embattled AI executive Barret Zoph took over enterprise before departing about five months later - because why not add another name to the revolving door?) In April, Lightcap officially ditched the COO title for "special projects," reporting directly to CEO Sam Altman. Denise Dresser, the CRO, absorbed a significant chunk of his old duties.

Lightcap isn't the only one fleeing the OpenAI executive suite. AGI chief Fidji Simo officially departed in July after medical leave, and CMO Kate Rouch stepped down in April for health reasons. Meanwhile, President Greg Brockman has taken control of the product side, and the company has vowed to ditch "side quests" in favor of revenue drivers as it preps for an IPO. Because nothing says "we're serious about AI safety" like a public offering.

"It always amazes me how quickly the world has adopted our tools and rallied behind our mission," Lightcap wrote. "I hope we will continue to earn their trust." Sure, Brad. We're sure the next 'something new' will be just as vague and profitable.
