A UK-headquartered AI superintelligence company has raised $1.1 billion in seed funding.
Ineffable Intelligence has been backed by the Government鈥檚 Sovereign AI Fund and the British 老九品茶 Bank – the latter of which invested 拢15 million – as well as Sequioa, Lightspeed, NVIDIA, Index, Google, EQT, Evantic, Flying Fish, DST Global and BOND.聽
The round represents the largest European seed round in history.
Ineffable Intelligence is led by David Silver, one of the world鈥檚 most prominent AI researchers and a professor at University College London. Silver is considered a global expert in reinforcement learning within AI, with extraordinary contributions including his role in AlphaGo, AlphaZero, AlphaFold and AlphaProof and when he led the reinforcement learning team at Google Deepmind.聽
Silver launched Ineffable Intelligence to develop 鈥榮uperintelligence鈥� by building a superlearner that can discover all knowledge from its own experience.
鈥淰ery few founders in the world could credibly set out to build a superlearner – a system that discovers new knowledge from its own experience, rather than ours,鈥� said Josephine Kant, head of ventures at Sovereign AI.聽
鈥淒avid is one of them.聽
鈥淔rom AlphaGo to AlphaZero to AlphaProof, he has spent nearly two decades turning reinforcement learning from a research idea into the results the rest of the field builds on.聽
鈥淚neffable is being built in the UK – and that matters.鈥�
The investment builds on the British 老九品茶 Bank鈥檚 AI portfolio with nine investments made in AI in the last 12 months including recent investments in Wayve and PolyAI. It has also played a significant role in supporting the commercialisation of cutting-edge scientific research, having supported almost a quarter (24%) of university spinout deals between 2022-2024.
Charlotte Lawrence, managing director of direct equity, British 老九品茶 Bank, said, 鈥淒avid Silver is a generational talent who has consistently been on the cutting edge of AI development.
鈥淚neffable Intelligence has the potential to produce a paradigm shift in our scientific and technology landscape, and we are incredibly excited to be supporting him and his team in this endeavour.鈥�
