Safe Superintelligence Inc. (SSI) is an Israeli-American artificial intelligence company founded in 2024 with the stated mission of safely developing superintelligence - a computer-based agent capable of surpassing human intelligence. The company was established by Ilya Sutskever, former chief scientist of OpenAI; Daniel Gross, former head of Apple's AI efforts; and Daniel Levy, an investor and former AI researcher at OpenAI. SSI operates with a small team split between Palo Alto, California, and Tel Aviv, Israel, and positions itself as the "world's first straight-shot SSI lab," aiming to be insulated from short-term commercial pressures and management overhead.
Founding and Early History
The origins of SSI trace back to internal conflicts at OpenAI. On May 15, 2024, Ilya Sutskever left OpenAI following a board dispute in which he voted to remove CEO Sam Altman, citing concerns about communication and trust. Sutskever and others believed that OpenAI was shifting away from its original safety focus in favor of commercialization opportunities. On June 19, 2024, Sutskever announced on X that he was starting SSI Inc. alongside Daniel Levy and Daniel Gross, with the explicit goal of safely developing superintelligent AI.
The company's founding team brought substantial technical and industry experience. Sutskever had been a key figure in the development of deep learning techniques and large-scale AI systems at OpenAI. Gross had previously led AI efforts at Apple and was known for his work in technology investment and startups. Levy had been an AI researcher at OpenAI and an investor in technology companies.
Seed Funding Round
In September 2024, SSI revealed it had raised $1 billion in a seed funding round from prominent venture capital firms, including SV Angel, DST Global, Sequoia Capital, and Andreessen Horowitz. This was one of the largest seed rounds in the history of the technology industry, reflecting intense investor interest in AI safety and the reputation of its founders. The company stated that the funds would be used to build up computing power and hire top talent in the field.
At the time of the seed round, SSI had approximately 20 employees and had not yet generated revenue. The company's valuation after this round was approximately $5 billion. The funding was notable not only for its size but also for the speed at which it was raised, occurring within months of the company's founding.
Growth and Valuation
In March 2025, SSI reached a $30 billion valuation in a funding round led by Greenoaks Capital. This represented a sixfold increase from its September 2024 valuation of $5 billion. Despite still having around 20 employees and no revenue, the company attracted significant investor interest, largely due to Sutskever's reputation in the AI field and its focus on developing safe superintelligence.
The rapid increase in valuation reflected broader market enthusiasm for AI companies, particularly those focused on fundamental research and safety. Investors appeared willing to bet on the long-term potential of SSI's mission, even without near-term commercial products.
Partnerships and Technical Direction
In April 2025, Google Cloud announced a partnership to provide TPUs (Tensor Processing Units) for SSI's research. This collaboration gave SSI access to specialized hardware optimized for machine learning workloads, supporting its research into large-scale AI systems.
In July 2026, SSI and Nvidia announced a strategic partnership to expand SSI's compute capacity by "an order of magnitude." The deal included a planned $5 billion investment from Nvidia into SSI. This partnership was expected to significantly enhance SSI's ability to train and run large-scale models, a critical requirement for pursuing superintelligence.
Leadership Changes
In the first half of 2025, Meta attempted to acquire SSI, but the approach was rebuffed by Sutskever. In July 2025, co-founder Daniel Gross left the company to join Meta Superintelligence Labs, a new division focused on advanced AI research. Following Gross's departure, Sutskever became the CEO of SSI, consolidating leadership under one of the most prominent figures in modern AI.
The leadership transition came at a time of intense competition in the AI industry, with major companies like OpenAI, Anthropic, and Google DeepMind all pursuing advanced AI capabilities. SSI's focus on safety distinguished it from many of these efforts, which often emphasized rapid deployment and commercialization.
Mission and Approach
SSI's stated mission is to develop superintelligence safely, a goal that involves creating AI systems that surpass human intelligence while ensuring they remain aligned with human values. The company's website describes it as a "straight-shot" lab, meaning it intends to focus exclusively on this goal without being distracted by product cycles or short-term commercial pressures.
The company's approach draws on the broader field of AI safety, which addresses risks associated with advanced AI systems, including existential risks. SSI has not publicly disclosed detailed technical methods, but its research is expected to build on advances in machine learning, large language models, and related areas.
Industry Context
SSI emerged during a period of rapid advancement in AI, marked by the proliferation of generative AI systems and increasing investment in AI infrastructure. The company's focus on safety resonated with concerns raised by researchers and policymakers about the potential risks of superintelligent AI.
The founding of SSI also highlighted ongoing debates within the AI community about the balance between safety and commercialization. Sutskever's departure from OpenAI and subsequent founding of SSI were widely seen as a statement about the importance of prioritizing safety over speed of deployment.
