OpenAI executive shuffle includes new role for COO Brad Lightcap to lead ‘special projects’

A handful of OpenAI executives are transitioning into new roles, according to a report from Bloomberg . An OpenAI spokesperson confirmed the personnel changes to TechCrunch.

CEO of AGI development Fidji Simo announced in a memo that Brad Lightcap, OpenAI’s COO, has a new job leading “special projects,” which will involve “complex deals and investments across the company.” He will report directly to CEO Sam Altman.

Denise Dresser, the former Slack CEO who recently joined OpenAI as chief revenue officer, will take over some of Lightcap’s commercial duties.

Simo also had news of her own to share: She will be taking medical leave for the next several weeks to navigate a neuroimmune condition.

“I have done everything possible to avoid it, but sadly my body isn’t cooperating,” Simo wrote in the memo obtained by Bloomberg.

“The timing is maddening because we have such an exciting roadmap ahead that the team is executing on, and I hate to miss even a minute of it,” she said.

While she is on leave, OpenAI co-founder and president Greg Brockman will manage product.

Kate Rouch, OpenAI’s marketing head, will also be stepping down from her role to focus on cancer recovery, but will return to a “different, more narrowly scoped role when her health allows,” the memo said. The company plans to search for a new CMO.

“We have a strong leadership team focused on our biggest priorities: advancing frontier research, growing our global user base of nearly 1 billion users, and powering enterprise use cases,” OpenAI told TechCrunch in a statement. “We’re well-positioned to keep executing with continuity and momentum.”
