# Safe Superintelligence's $20 Billion Funding Round (2025) Safe Superintelligence (SSI) raised $20 billion in a 2025 funding round at a $100 billion valuation, led by Greenoaks, marking one of the largest AI investments ever. Safe Superintelligence Inc. (SSI) is an American artificial intelligence company founded by Ilya Sutskever, Daniel Gross, and Daniel Levy, focused on developing superintelligent AI safely. In 2025, the company raised $20 billion in a funding round led by Greenoaks, achieving a $100 billion valuation, making it one of the most valuable private AI companies globally. The round, announced in 2025, represented a significant leap from SSI's previous valuation of $30 billion in March 2025. Despite having only around 20 employees and no revenue, the company attracted substantial investor interest due to its mission and the reputation of its co-founders, particularly Sutskever, former chief scientist at OpenAI. ## Background and Founding SSI was founded in June 2024 by Ilya Sutskever, Daniel Gross, and Daniel Levy. Sutskever had left OpenAI in May 2024, following his role in the November 2023 board decision to remove Sam Altman as CEO. Sutskever had compiled a 70-page dossier alleging a pattern of dishonesty by Altman and believed OpenAI was prioritizing commercialization over safety. After the backlash, Sutskever apologized and briefly considered returning, but ultimately departed to start SSI with the goal of pursuing superintelligence safely. Daniel Gross, former head of Apple's AI efforts, and Daniel Levy, an investor and former AI researcher at OpenAI, joined as co-founders. The company's mission is to build superintelligence - an AI system surpassing human intelligence - while ensuring safety, a concept often discussed in the context of [existential-risk-from-ai](https://www.wikiprompt.org/wiki/existential-risk-from-ai). ## Funding History SSI's first funding round occurred in September 2024, raising $1 billion from investors including SV Angel, DST Global, [sequoia-capital](https://www.wikiprompt.org/wiki/sequoia-capital), and [andreessen-horowitz](https://www.wikiprompt.org/wiki/andreessen-horowitz). This round valued the company at $5 billion. The funds were intended for computing power and hiring top talent. In March 2025, SSI raised additional capital at a $30 billion valuation, led by Greenoaks Capital, a sixfold increase from the previous valuation. The round attracted attention despite the company's small size and lack of revenue, reflecting investor confidence in the team and mission. The $20 billion round in 2025, also led by Greenoaks, increased the valuation to $100 billion. This made SSI one of the most valuable private AI companies, comparable to [openai](https://www.wikiprompt.org/wiki/openai) and [anthropic](https://www.wikiprompt.org/wiki/anthropic). The round underscored the intense investor appetite for AI safety-focused ventures, even amid concerns about [ai-safety](https://www.wikiprompt.org/wiki/ai-safety) and the potential for [superintelligence](https://www.wikiprompt.org/wiki/superintelligence). ## Strategic Partnerships and Acquisitions In April 2025, [google-cloud](https://www.wikiprompt.org/wiki/google-cloud) announced a partnership to provide Tensor Processing Units (TPUs) for SSI's research, enhancing its computational capabilities. This partnership was part of SSI's strategy to secure [compute](https://www.wikiprompt.org/wiki/compute) resources for training advanced models. In the first half of 2025, [meta](https://www.wikiprompt.org/wiki/meta) attempted to acquire SSI, but Sutskever rebuffed the offer. In July 2025, co-founder Daniel Gross left SSI to join Meta Superintelligence Labs, and Sutskever became CEO. The departure did not derail SSI's growth, and the company continued to attract investment. On 27 July 2026, SSI and [nvidia](https://www.wikiprompt.org/wiki/nvidia) announced a strategic partnership to expand SSI's compute by an order of magnitude, with a planned $5 billion investment from Nvidia. This partnership positioned SSI to leverage Nvidia's advanced hardware for large-scale AI research. ## Company Culture and Operations SSI operates with a small team split between Palo Alto, California, and Tel Aviv, Israel. The company's website describes it as the "world's first straight-shot SSI lab," aiming to be free from "management overhead or product cycles" and insulated from short-term commercial pressures. Employees are discouraged from listing their affiliation on LinkedIn, partly due to increased poaching in 2025. SSI's US headquarters are at 317 University Avenue, Palo Alto. In February 2025, the company leased offices at 144 Menachem Begin Road in Midtown Tel Aviv, expanding its presence in Israel. ## Impact and Significance The $20 billion round at a $100 billion valuation highlighted the growing importance of AI safety in the industry. SSI's focus on safe superintelligence differentiated it from other AI labs, which often prioritize commercial applications. The round also reflected broader trends in AI investment, with major players like [a16z-ai](https://www.wikiprompt.org/wiki/a16z-ai) and [sequoia-capital](https://www.wikiprompt.org/wiki/sequoia-capital) backing safety-oriented ventures. The funding enabled SSI to scale its research, attract top talent, and secure partnerships with major cloud and hardware providers. The Nvidia partnership, in particular, was expected to significantly boost SSI's computational capacity, essential for training superintelligent systems. ## Challenges and Future Outlook Despite its valuation, SSI faced challenges, including the departure of a co-founder and the inherent difficulties of achieving superintelligence safely. The company's reliance on a small team and its focus on long-term goals rather than immediate products posed risks, but also allowed for a unique research culture. As of 2025, SSI had not generated revenue, but its valuation suggested investors believed in its potential to transform AI. The company's trajectory will likely depend on progress in [artificial-general-intelligence](https://www.wikiprompt.org/wiki/artificial-general-intelligence) and the broader [ai-safety](https://www.wikiprompt.org/wiki/ai-safety) landscape. ## See Also - [ai-safety](https://www.wikiprompt.org/wiki/ai-safety) - [artificial-general-intelligence](https://www.wikiprompt.org/wiki/artificial-general-intelligence) - [existential-risk-from-ai](https://www.wikiprompt.org/wiki/existential-risk-from-ai) - [openai](https://www.wikiprompt.org/wiki/openai) - [superintelligence](https://www.wikiprompt.org/wiki/superintelligence) ## References - Source facts from Wikipedia (CC BY-SA). ## External Links - Official website (not provided). ## External links - [Wikipedia: Safe Superintelligence](https://en.wikipedia.org/wiki/Safe_Superintelligence) --- Source: https://www.wikiprompt.org/wiki/safe-superintelligence-2025-20b-round License: CC BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/) Last updated: 2026-10-13T12:36:00.731089+00:00
