OpenAI unveiled a significant restructuring on Friday. This comes as Fidji Simo, the company’s CEO for AGI deployment, commences a health-related sabbatical to prioritize her well-being. During Simo’s absence, OpenAI President Greg Brockman will oversee the product divisions. Her prior designation had been Chief Executive of applications.
Brad Lightcap, OpenAI’s head of operations and one of CEO Sam Altman’s key lieutenants, is shifting into a “special initiatives” capacity. Concurrently, Kate Rouch, the chief marketing officer, is commencing a sabbatical to concentrate on her well-being. Rouch has been receiving treatment for breast cancer. Upon her return, she will occupy “a distinct, more precisely defined position,” as per a memo Simo disseminated among OpenAI personnel, seen by WIRED.
“As I disclosed upon my arrival, I experienced a recurrence of my neuroimmune ailment several weeks prior to commencing employment,” Simo stated in the memorandum, which was circulated within OpenAI’s “core” Slack channel. “The period since has been quite turbulent, and the last month has been especially challenging regarding my health. Throughout my tenure here, I’ve deferred diagnostic examinations and novel treatments to remain entirely dedicated to my responsibilities and avoid missing any workdays. I initially took a break for medical evaluations a fortnight before this current hiatus, and it’s now evident I have overexerted myself, and I genuinely require novel interventions to steady my health.”
Simo is anticipated to be absent for “multiple weeks,” as indicated in her internal communication.
Within his fresh capacity, Lightcap will be responsible for overseeing the company’s on-site engineering teams. These teams integrate directly into corporate entities and assist in incorporating OpenAI’s innovations, among additional responsibilities.
OpenAI will commence the search for a new Chief Marketing Officer, Simo conveyed. Furthermore, the company is seeking a head of communications to succeed Hannah Wong, who departed her role in January. Chris Lehane has assumed leadership of the communications division temporarily.
“We possess a robust leadership cadre concentrating on our primary objectives: pioneering cutting-edge research, expanding our worldwide user community nearing 1 billion individuals, and enabling business applications,” an OpenAI representative asserted in a declaration. “We are optimally situated to proceed with sustained execution and impetus.”
Simo commenced her tenure at OpenAI in August 2025, where she assumed charge of numerous of the company’s customer-oriented offerings, such as ChatGPT, Codex, and the social-video application Sora. She lately discontinued the Sora application and informed personnel that the corporation needed to curtail ancillary ventures and re-center on its primary offerings.
This development transpires as OpenAI contemplates an initial public offering as early as this year. The company lately secured $122 billion in the most substantial investment round witnessed in the technology sector to date, which appraised the enterprise at $852 billion.
