Safe Superintelligence Inc. (SSI) is an Israeli-American artificial intelligence company founded in June 2024 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. The company's stated mission is to focus exclusively on safely developing superintelligence - a computer-based agent capable of surpassing human intelligence - while insulating itself from short-term commercial pressures. SSI operates with a small team split between Palo Alto, California, and Tel Aviv, Israel, and has attracted significant investor interest due to its founders' reputations and its singular focus on AI safety.
Founding and Early History
On May 15, 2024, Ilya Sutskever left OpenAI after a board dispute in which he voted to fire CEO Sam Altman, citing concerns about communication and trust. Sutskever and others believed that OpenAI was neglecting its original focus on safety 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 goal of safely developing superintelligent AI. The company's website describes it as the "world's first straight-shot SSI lab," intended to be unaffected by "management overhead or product cycles" and "insulated from short-term commercial pressures."
The $1 Billion Funding Round (September 2024)
In September 2024, SSI revealed it had raised $1 billion from venture capital firms including SV Angel, DST Global, Sequoia Capital, and Andreessen Horowitz. This round valued the company at $5 billion, despite the fact that SSI had no revenue and only about 20 employees at the time. The funds were earmarked for building up computing power and hiring top talent in the field of artificial intelligence. The round was notable for its size and speed, reflecting strong investor confidence in Sutskever's vision and the growing demand for AI safety solutions.
Subsequent Funding and Valuation Growth
In March 2025, SSI reached a $30 billion valuation in a funding round led by Greenoaks Capital, six times its previous $5 billion valuation from September 2024. This rapid increase occurred despite the company still not generating revenue and maintaining a workforce of approximately 20 employees. Investor interest was largely driven by Sutskever's reputation as a leading AI researcher and the company's exclusive focus on safe superintelligence development. The valuation placed SSI among the most valuable private AI companies, comparable to established players like OpenAI and Anthropic.
Partnerships and Compute Expansion
In April 2025, Google Cloud announced a partnership to provide TPUs (Tensor Processing Units) for SSI's research, giving the company access to specialized hardware for training large models. In the first half of 2025, Meta attempted to acquire SSI but was rebuffed by Sutskever, who preferred to keep the company independent. On July 27, 2026, SSI and Nvidia announced a strategic partnership to expand SSI's compute by "an order of magnitude," with the deal including a planned $5 billion investment from Nvidia. This partnership was designed to significantly scale SSI's computational resources, enabling more ambitious research into large language models and other AI systems.
Leadership and Team
Ilya Sutskever serves as CEO of SSI, a role he assumed after co-founder Daniel Gross left the company in July 2025 to join Meta Superintelligence Labs. Daniel Levy remains involved as a co-founder and researcher. The team is intentionally small, composed of researchers and engineers selected for their expertise in deep learning and AI safety. The company's structure emphasizes research over product development, with a flat hierarchy and a focus on long-term goals rather than quarterly results. This approach has attracted talent from major AI labs, including former employees of OpenAI and Google DeepMind.
Mission and Approach to AI Safety
SSI's mission is to develop superintelligence - an AI system that surpasses human intelligence - while ensuring it is safe and aligned with human values. The company distinguishes itself from other AI labs by making safety the primary objective rather than a secondary consideration. Its approach involves research into alignment techniques, interpretability, and robust AI architectures, drawing on work in machine learning and neural networks. SSI's founders have argued that the race to develop advanced AI must be accompanied by rigorous safety measures to prevent existential risks. The company's "straight-shot" philosophy means it avoids diversifying into commercial products, instead dedicating all resources to achieving its safety-focused goal.
Industry Context and Reception
The founding of SSI came at a time of heightened concern about AI safety, following the rapid deployment of generative AI systems and debates about their potential risks. Sutskever's departure from OpenAI and his subsequent founding of SSI were widely covered in the technology press, with many commentators viewing it as a validation of safety concerns. The company's high valuations, despite minimal revenue, were seen as a bet on the future importance of safe AI development. SSI operates in a competitive landscape that includes major AI labs like OpenAI, Anthropic, and Google DeepMind, as well as startups focused on AI safety research. Its partnerships with cloud providers and hardware companies have positioned it to scale its research capabilities while maintaining its independent focus.
