Funding timelineThe 'straight-shot' safety lab that raised US$8B before shipping a product
Safe Superintelligence Inc. (SSI) is an Israeli-American AI company founded in June 2024 by Ilya Sutskever (OpenAI's former chief scientist), Daniel Gross (former head of Apple's AI efforts) and Daniel Levy, operating from Palo Alto and Tel Aviv. It calls itself the world's 'first straight-shot SSI lab' — no products, no commercial roadmap, only the goal of safely building superintelligence, insulated from short-term commercial pressure. Despite shipping nothing, it raised US$1B at a US$5B valuation (September 2024), US$2B at US$32B (April 2025, led by Greenoaks with Alphabet and Nvidia joining) and a US$5B Nvidia strategic investment (July 2026) that scaled its compute 'by an order of magnitude' — roughly US$8B cumulative at a ~US$32B valuation with no revenue. Sutskever took over as CEO when co-founder Daniel Gross left in July 2025; Daniel Levy became president.
Every disclosed equity round for Safe Superintelligence (SSI), oldest to newest, with lead and participating investors where reported.
Three-month-old SSI raised US$1B at a reported US$5B valuation — a staggering mark for a pre-product, ~10-person startup.
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.
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).
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.
