UK organisations advancing the science of artificial intelligence.
Growth Cambridge
Builds AI models that discover and design new materials, starting with compounds that capture carbon. Headquartered in Cambridge and founded in 2024 by researchers with roots in Google DeepMind and academia.
Early-stage London
Builds in-memory-compute AI inference chips designed to speed up large-language-model inference and cut its cost. Headquartered in London.
Early-stage London
Builds decentralised infrastructure for training, verifying, and coordinating machine learning across distributed compute. Headquartered in London.
Acquired London
Runs one of the world's leading AI research labs, behind breakthroughs including AlphaFold, AlphaGo, and the Gemini family of models. Headquartered in London and part of Google, it anchors much of the UK's AI research base.
Acquired Bristol
Designs AI accelerator processors, its Intelligence Processing Units, and the systems and software that run machine-learning workloads on them. Headquartered in Bristol.
Seed London
Builds reinforcement-learning systems designed to discover new knowledge and skills without relying on human-generated data. Founded in 2025 by David Silver, the former head of reinforcement learning at Google DeepMind and a lead researcher behind AlphaGo and AlphaZero. Headquartered in London.
Growth London
Applies AI to drug discovery, using models descended from AlphaFold to predict how molecules behave and design new medicines. Headquartered in London as an Alphabet company spun out of DeepMind.
Seed Oxford
Develops 3D optical computing hardware to accelerate AI inference at lower energy cost. A University of Oxford spinout, headquartered in Oxford.
Early-stage Oxford
Builds machine-learning software for high-stakes uses in defence, national security, government and insurance. An Oxford University spin-out headquartered in Oxford.
Growth London
Develops open generative-AI models spanning image, video, audio and 3D, best known for the Stable Diffusion family of image models. Headquartered in London.
New PitchBook figures show UK startups raised £14.4B in the first half of 2026, with more than 70% of it going to AI and the UK taking close to 40% of all European AI funding. It is the data behind a year of big rounds, and a sign of how sharply capital is concentrating.
The UK government's AI Security Institute has stood up a dedicated Control Red Team to stress-test the safeguards that frontier labs rely on. It reported finding vulnerabilities in every version of the internal safety monitors used by Anthropic and Google DeepMind, sharpening the UK's role in frontier-AI oversight.
Cambridge company CuspAI has raised around £334M to scale its AI system for discovering new materials, in one of the largest UK AI rounds of the year. The round was led by Kleiner Perkins and NEA, with Britain's Sovereign AI Venture Fund among the backers.
Isomorphic Labs, the London drug-discovery company spun out of Google DeepMind, has raised $2.1B in its first external round, led by Thrive Capital with backing from Alphabet and GV. The money is meant to carry its AI-designed drugs toward the clinic.
