David Silver’s New Venture Secures $5.1 Billion Backing from Sequoia and Nvidia

Published on April 27, 2026

After over a decade at Google DeepMind, David Silver departed in late 2025. He played a pivotal role in developing groundbreaking AI projects like AlphaGo and AlphaZero. Now, he is stepping into the spotlight with his latest initiative, Ineffable Intelligence.

Founded in November 2025, Ineffable Intelligence has yet to launch a product or generate revenue. However, it has already attracted significant investments, securing $5.1 billion in backing from high-profile firms like Sequoia and Nvidia. Silver’s proven track record in AI offers a compelling reason for such grand financial support.

Details about Ineffable Intelligence remain scarce, including its intended applications and roadmap. Investors are betting on Silver’s thesis of superhuman intelligence, a vision that has yet to be realized. His past successes lend a sense of urgency and confidence to this new venture.

The large investment raises questions about the future of AI development. With no established products, the stakes are high, and the landscape is evolving. Silver’s ambitious goals could potentially shift the dynamics of the emerging AI market, setting new standards for innovation.
