Sequoia Leads Historic $1B Seed for Ex-DeepMind Scientist’s London AI Lab
Sequoia Capital is leading a $1 billion seed round for Ineffable Intelligence, a London-based AI startup founded by ex-Google DeepMind researcher David Silver, valuing the venture at about $4 billion. If closed at $1 billion, it would be Europe’s largest seed round. The company plans to build superhuman AI trained through experience and environment interaction via reinforcement learning, continuing Silver’s work on AlphaGo/AlphaStar and Google's Gemini LLMs while drawing interest from Nvidia, Microsoft and OpenAI-linked backers.
