Safe Superintelligence Inc. (SSI) is an Israeli-American artificial intelligence company focused on developing superintelligence, a computer-based agent capable of surpassing human intelligence, with an emphasis on safety. Founded in June 2024 by prominent AI figures Ilya Sutskever, Daniel Gross, and Daniel Levy, the company received $1 billion in funding in September 2024 to expand its computing resources and recruit top talent. SSI operates with a small team split between Palo Alto, California, and Tel Aviv, Israel, and aims to avoid short-term commercial pressures in pursuit of its long-term safety mission.
The company emerged from a period of turmoil at OpenAI, where co-founder Ilya Sutskever had played a pivotal role in developing modern large language models. SSI's funding round drew attention from major venture capital firms, reflecting both the reputation of its founders and the growing interest in safe artificial intelligence development. By March 2025, SSI's valuation had surged to $30 billion, despite having approximately 20 employees and no revenue, highlighting investor confidence in its approach.
Founding and Leadership
SSI was founded on June 19, 2024, when Ilya Sutskever announced the venture on social media platform X. Sutskever, who had served as chief scientist at OpenAI for nearly a decade, departed that organization on May 15, 2024, following a board dispute in which he voted to remove CEO Sam Altman amid concerns about communication and trust. Sutskever and colleagues believed OpenAI was prioritizing commercialization over its original safety commitments.
Sutskever was joined by Daniel Gross, former head of Apple's AI efforts, and Daniel Levy, an investor and former AI researcher at OpenAI. The trio positioned SSI as what its website calls the "world's first straight-shot SSI lab," designed to be insulated from "management overhead or product cycles" and "short-term commercial pressures." In July 2025, Gross departed to join Meta Superintelligence Labs, leaving Sutskever as sole CEO.
September 2024 Funding Round
In September 2024, SSI revealed it had raised $1 billion from a group of venture capital firms including SV Angel, DST Global, Sequoia Capital, and Andreessen Horowitz. The funding was allocated to building up computing power and hiring leading researchers in the field. The round valued the company at $5 billion, a substantial figure for a startup with no product and a small workforce.
The investment was notable given the competitive landscape of generative AI development, where companies like OpenAI, Anthropic, and Google DeepMind were spending heavily on infrastructure. SSI's approach differed by emphasizing safety research over rapid deployment, attracting investors who saw long-term value in responsible superintelligence development.
Computing Infrastructure
SSI's September 2024 funding was earmarked in part for expanding computing capabilities, essential for training advanced neural networks. The company initially relied on existing cloud services but sought dedicated partnerships to scale its operations.
In April 2025, Google Cloud announced a partnership to provide tensor processing units (TPUs) for SSI's research. This arrangement gave SSI access to specialized hardware optimized for deep learning workloads, complementing its internal research efforts. The partnership reflected a broader trend of AI labs partnering with cloud providers to secure computational resources.
On July 27, 2026, SSI and Nvidia announced a strategic partnership to expand SSI's compute by "an order of magnitude," with Nvidia planning to invest $5 billion. The deal underscored the growing importance of specialized neural network hardware in frontier AI research, as well as SSI's need for substantial computational capacity.
Mission and Approach
SSI's stated mission is to develop superintelligence safely, treating safety as a core research problem rather than an afterthought. The company's website describes it as the "world's first straight-shot SSI lab," indicating a singular focus on achieving superintelligence without diversifying into products or services. This contrasts with many AI companies that balance research with commercial applications.
The founders argued that AI safety has been underemphasized in the rapid race toward advanced systems. Sutskever, who co-invented key components of modern AI including the Transformer architecture and multi-head attention, has long advocated for careful consideration of AI risks. SSI's approach involves pursuing fundamental safety research alongside capability development, rather than treating safety as an afterthought.
Mission and Approach
SSI's stated mission is to safely develop superintelligence, defined as an AI system surpassing human cognitive abilities across all economically valuable tasks. The company's organizational structure and research direction prioritize safety as a core design principle, with the goal of creating systems that are both highly capable and aligned with human values.
The company's website emphasizes its independence from typical startup pressures, suggesting that SSI is structured to pursue long-term research goals without being forced to ship products prematurely. This approach resonates with concerns in the machine learning community about the potential risks of advanced AI systems, including existential risks.
Subsequent Developments and Valuation
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. The company had not generated revenue, yet attracted significant investor interest largely due to Sutskever's reputation and its focus on safe superintelligence. In April 2025, Google Cloud announced a partnership to provide tensor processing units for SSI's research.
In the first half of 2025, Meta attempted to acquire SSI, but Sutskever rebuffed the overture. The company continued to grow its technical capabilities, and in July 2026, it entered a strategic partnership with Nvidia. The partnership aimed to scale SSI's compute by "an order of magnitude," with a planned $5 billion investment from Nvidia, announced on July 27, 2026.
Valuation and Investor Interest
SSI's valuation trajectory has been remarkable. The September 2024 funding round valued the company at $5 billion desirably. In March 2025, a funding round led by Greenoaks Capital raised SSI's valuation to $30 billion, a sixfold increase despite the company's small team size and lack of revenue. This valuation reflected investor confidence in Sutskever's technical leadership and the strategic importance of AI safety.
Investors included prominent venture capital firms such as Sequoia Capital, Andreessen Horowitz, and DST Global, alongside later participation from Greenoaks Capital in the March 2025 round.
