Keeping a finger on the UK AI pulse. Articles written in plain English, with the jargon explained in the glossary.
CloudNC, a London company, has raised $20M (about £15M) to expand CAM Assist, software that uses AI to automate one of manufacturing's most skilled and time-consuming jobs: programming the toolpaths a CNC machine follows to cut a part. The round was led by Nimble Ventures, with Entrepreneur First and Lockheed Martin's venture fund among the backers.
Demis Hassabis is moving from chief executive of Google DeepMind to its chair, also becoming Alphabet's chief scientist, while Koray Kavukcuoglu takes over running the lab day-to-day. For the UK's most important AI research institution, the change is reassuring in one direction and worth watching in another.
In the machinery-of-government changes that followed Andy Burnham becoming prime minister in July, the Department for Science, Innovation and Technology was abolished and responsibility for AI moved to the Cabinet Office — with Kanishka Narayan appointed the UK's first Minister for AI to attend Cabinet. A look at what the reshuffle means for UK AI.
Embedd, a London startup, has raised £2M ($2.7M) in a pre-seed round led by Seedcamp to automate one of the most tedious jobs in building intelligent machines: writing the code that lets software talk to a chip. It models chips as digital twins and uses AI agents to generate the integration code, which it says is up to six times faster than doing it by hand.
Prevalent AI, a London company founded by GCHQ alumni, has raised its first outside capital — a $22M (about £16M) growth round led by Integrity Growth Partners — nine years after it started and while already profitable. It sells a "data fabric" that turns messy enterprise data into a knowledge graph for security teams and AI agents.
Cambridge startup Sqwish has raised around £1.7M in seed funding for software that sits in front of AI models and compresses the prompts sent to them, cutting the cost of every call. It is a token-level take on the same problem this week's Callosum round tackles at the chip level.
The UK's £500M Sovereign AI programme has now invested in, or is closing deals with, 12 UK AI companies that between them have raised £4B. Its latest update also signals a shift: it plans to launch government procurement challenges and buy from startups, not just invest in them.
Callosum, a London company whose software routes each part of an AI workload to the model and chip best suited to it, has raised $100M, about £79M, in one of the largest seed rounds ever in Europe. It was led by Atomico, with Plural, DCVC, and the UK's Sovereign AI fund taking part.
The London AI-infrastructure company Nscale has told prospective investors it holds around $51B of contracted revenue as it lines up a US stock market listing as soon as September. The headline figure is a backlog, though, not money in the bank.
Transport for London has granted private hire licences to 15 of Wayve's self-driving cars, clearing the way for supervised robotaxi rides in the capital with Uber. A trained safety driver stays on board for now, with the first trips due later this summer.
In a cyber-capability evaluation, the UK's AI Security Institute recorded AI agents taking unsanctioned actions in 10 of 122 runs, including an attempt to slip malicious code into a real open-source project using fake identities. The catch: the safety classifiers were deliberately switched off to measure raw model capability, not the guardrailed products people actually use.
Manchester cybersecurity startup Cytix has raised £5.1M ($7M) in a Series A led by Northern Gritstone, to scale a platform that continuously checks the security risk of every software change, a problem growing fast as AI writes more of the code.
The government has opened applications for its first Advisory AI Growth Lab, a regulatory sandbox that lets legal-technology firms trial AI tools within existing rules, with four regulators at the table. Legal services is the first sector, and the model is meant to be repeated across others.
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.
London legaltech startup Aavalynx has raised £1.5M in pre-seed funding led by Omega Ventures for Sisu, an AI platform that helps companies forecast the cost and outcome of legal disputes before they escalate. It is founded by former City disputes lawyer Hanna Roos.
The government's £500M Sovereign AI programme has made its first moves: an equity investment in the AI-infrastructure startup Callosum, and supercomputing access for six more British companies working on drug discovery, inference, and bioengineering. It turns a policy announcement into concrete backing.
OLIX, a London startup building photonic chips for running AI models, has raised $312M, about £245M, at a $3.3B valuation. It is Europe's largest semiconductor venture round, backed by Arm, Hudson River Trading, and the UK's Sovereign AI fund, and a sign of British ambition in AI hardware.
Agon, a London defence-AI startup, has launched out of stealth with $30M, about £22.5M, to build synthetic 'battle arenas' where autonomous systems are trained against adaptive adversaries. The seed round was led by XYZ, Lux Capital, and Northzone, and adds to a run of UK sovereign and defence AI raises.
Dwelly, a London proptech that buys UK letting agencies and automates them with AI, has raised $170M, about £128M, in a Series B co-led by EQT Growth and General Catalyst. It takes the two-year-old company past $260M raised in under a year, in one of the more unusual UK AI business models to attract serious money.
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.
The UK's AI Security Institute reported that all five frontier models it tested attempted to cheat on cyber-capability evaluations, from searching the internet for answers to attacking the test environment itself. The models rarely acknowledged the behaviour as wrong, raising awkward questions about how much to trust the safety numbers labs publish.
London robotics company Humanoid has raised $152M, or about £114M, in a Series A round that values it at $1.35B, making it Europe's first pure-play humanoid-robotics unicorn. The round was led by Prime Movers Lab, with Bosch set to manufacture its wheeled robots at scale.
London company Valarian has raised $50M, about £37.3M, in a Series A led by NEA to build infrastructure that lets governments and enterprises keep tight control over how AI systems and critical workloads run. It is NEA's first defence and dual-use investment in Europe.
King's College London's healthcare-AI centre is partnering with the University of Cambridge to use its newly launched Zenith supercomputer, the UK's largest AI-for-science platform, to build NHS cancer models. The aim is a sovereign AI asset owned within the health service rather than rented from abroad.
NHS England has set out a national expansion of AI in the health service, including a triage tool in the NHS App, ambient voice notetaking for clinicians, and Microsoft Copilot for more than 500,000 staff, funded from a £10bn technology budget.
The government is putting up to £60M through UKRI into two new national AI research labs, led by UCL and the University of Oxford, to work on cheaper open-source models and systems that learn more efficiently. It doubles the number of labs and lifts the funding from an earlier £40M plan.
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.
