OpenAI alumni startups take shape
New details on former OpenAI executives Murati and Sutskever’s startups.

Mira Murati
The former CTO (and briefly the CEO) of OpenAI announced her departure in September 2024 amid a flurry of resignations.

In September 2024, Sutsekver revealed that SSI had raised $1 billion from Andreesen Horowitz, Sequoia Capital, and others.
Now, Bloomberg is reporting that Sutskever is raising an additional $1 billion, led by Greenoaks Capital Partners, and that SSI has a $30 billion valuation. The startup is focusing on achieving AGI with a focus on safety, but it hasn’t revealed any specific plans yet.
