Unlock: Ineffable Intelligence

British AI lab founded by David Silver (UCL professor, ex-DeepMind reinforcement-learning lead, AlphaGo / AlphaZero / AlphaProof). Announced a $1.1 billion seed round at $5.1 billion valuation on April 27, 2026 — co-led by Sequoia and Lightspeed, with Nvidia, Google, DST Global, Index Ventures, and the UK Sovereign AI Fund participating. Stated mission: build a 'superlearner' that acquires knowledge from its own experience rather than from human-generated data, instantiating the 'Era of Experience' research agenda.
