UK-based Ineffable Intelligence, founded by former DeepMind researcher David Silver, has raised $1.1 billion in a seed funding round led by U.S. venture capital firms Sequoia Capital and Lightspeed, with backing from the British government. The round - Europe's largest seed financing to date - included participation from Nvidia and Google, and values Ineffable at $5.1 billion, the company said on Monday. The British government said its Sovereign AI initiative and the British Business Bank will co-invest in Ineffable as it seeks to strengthen domestic artificial intelligence capabilities in the global race for the technology.
