Safe Superintelligence Inc.

On June 19, 2024, Ilya Sutskever co-founded Safe Superintelligence Inc (SSI) with Daniel Levy and Daniel Gross after leaving OpenAI, where he had voted to fire Sam Altman over safety concerns. SSI's mission is developing safe superintelligence with no products or revenue until the goal is achieved, deliberately insulated from commercial pressures. By April 2025, SSI raised $3 billion total ($1B Series A, then Series B at $30B, Series C at $32B valuation) from Sequoia, Andreessen Horowitz, Greenoaks, and others. Sutskever rebuffed a Meta acquisition attempt, maintaining SSI's independent safety-first approach.
