OpenAI co-founder Ilya Sutskever says he is stepping into the CEO role at Safe Superintelligence, the AI startup he launched in 2024. In a post on X, Sutskever confirmed Thursday that Daniel Gross, the startup’s co-founder and CEO, departed the company as of June 29. Safe Superintelligence co-founder Daniel Levy is becoming president of the startup, according to Sutskever.
The announcement follows weeks of reporting that Meta CEO Mark Zuckerberg was in advanced talks to hire Gross, as well as his longtime investing partner, former GitHub CEO Nat Friedman. At one point, Zuckerberg reportedly attempted to acquire all of Safe Superintelligence, a startup most recently valued at $32 billion. Sutskever addressed those reports as well.
“You might have heard rumors of companies looking to acquire us. We are flattered by their attention but are focused on seeing our work through,” said Sutskever. “We have the compute, we have the team, and we know what to do. Together we will keep building safe superintelligence.”
I sent the following message to our team and investors:

As you know, Daniel Gross’s time with us has been winding down, and as of June 29 he is officially no longer a part of SSI. We are grateful for his early contributions to the company and wish him well in his next… — Ilya Sutskever (@ilyasut) July 3, 2025
Naturally, Gross’ departure may raise questions around the startup. If Safe Superintelligence was close to its goal — surely a groundbreaking technology, as it’s described — why would its co-founder leave to start something new, seemingly at Meta?
Notably, Safe Superintelligence describes themselves as the world’s “first straight-shot SSI lab,” meaning the company has no other products or ambitions outside of developing, well, safe superintelligence. That’s the name, that’s the product, that’s their whole thing. Sutskever started Safe Superintelligence shortly after leaving OpenAI, where he played a role in the brief ousting of CEO Sam Altman.
Meanwhile, it seems likely that Meta Superintelligence Labs will develop technology that powers lots of the company’s products. In Zuckerberg’s memo announcing the new unit, he referenced Meta’s expertise in building and growing products that reach billions of people, and cited the early wins Meta has had in AI wearables.
