Funding timelineSafe Superintelligence Inc. is Ilya Sutskever's Israeli-American lab pursuing superintelligence with no products and no commercial roadmap.
Every disclosed equity round for Safe Superintelligence (SSI), newest to oldest, with lead and participating investors where reported. Data is stored oldest-first; the timeline is displayed latest-first.
SSI and Nvidia announced a strategic partnership expanding SSI's compute 'by an order of magnitude,' including a planned US$5B Nvidia investment (with a Vera Rubin supply component).
Led by Greenoaks (~US$500M) with a16z, Lightspeed and DST; Alphabet and Nvidia also backed the company, and Google Cloud became a major infrastructure provider. ~6x the September 2024 valuation in seven months, still pre-product.
Three-month-old SSI raised US$1B at a reported US$5B valuation — a staggering mark for a pre-product, ~10-person startup.
SSI's funding history is a pure bet on people and mission: ~US$8B raised with no product, no revenue and (at the last equity round) about twenty employees. The valuation — US$5B at three months old, US$32B at ten months — prices Sutskever's track record (GPT-era OpenAI) and the credibility of a lab with no commercial distractions.
SSI's charter rejects product cycles and management overhead by design: one mission (safe superintelligence), one team, research insulated from commercial pressure. That structure is precisely what lets investors value it on mission rather than milestones — and what makes each round a referendum on Sutskever himself.
In July 2025 co-founder and CEO Daniel Gross departed (amid reports Meta tried to acquire the whole company), with Sutskever stepping into the CEO role and Levy becoming president. The transition occurred without any product or revenue event — the company's value stayed pinned to its founding team's reputation.
Like every frontier lab, SSI's capital is really compute: the 2024 round funded capacity and talent, Alphabet/Nvidia joined the 2025 round while Google Cloud supplied TPUs, and the 2026 Nvidia deal (Vera Rubin supply + US$5B) scaled compute by an order of magnitude. Each round trades equity for the hardware needed to eventually train a superintelligent system.

Because the asset being underwritten is Sutskever himself: the US$1B seed came at three months old with roughly ten people, and the US$32B round ten months in was still pre-product. Per employee that is on the order of US$400M raised — about twenty times Thinking Machines' US$2B seed across a ~100-person team — insulated by a charter that bans commercial distraction.
Because it was struck as infrastructure, not a repricing: the July 2026 deal paired the planned US$5B with Vera Rubin supply and an order-of-magnitude compute expansion, holding the US$32B mark set in April 2025. GPU access was the binding input — the logic behind xAI's US$10B debt-plus-equity packages for Colossus — so SSI traded a flat price for hardware scale.
A co-founder left instead of a deal closing: Daniel Gross departed in July 2025 amid reports Meta had explored acquiring the whole company, with Sutskever becoming CEO and Daniel Levy president. The next major money — Nvidia's planned US$5B — arrived a year later at the same US$32B, so the turbulence repriced nothing: the market underwrites Sutskever personally, not the trio as a unit.
It is the largest price attached to zero revenue in this dataset: US$32B against Anthropic's US$965B on ~US$47B annualized, Cognition's US$48B on ~US$900M run-rate, and Ineffable's ~US$5.1B post-money — also pre-revenue, but a sixth the size. On conventional multiples SSI is unpriceable, which is the design: rounds re-rate credibility, not output, and there is no revenue line to disagree with.
Because a pre-product lab still needs both supply lines: the April 2025 round brought in Alphabet and Nvidia while Google Cloud became a major TPU provider, and the 2026 Nvidia deal deepened the GPU side by an order of magnitude. Anthropic runs the same dual-supplier logic at commercial scale with Google and Amazon — SSI simply contracted it before shipping anything at all.
