TL;DR: NVIDIA is doubling down on Britain. This week in London, CEO Jensen Huang announced new planned investments in five UK startups: Boltz, Foresight, Hiverge, Prima Mente and Riverlane. Separately, NVIDIA committed a compute donation valued at $250 million over five years, or $50 million a year, to UK research on making AI agents safe and secure. NVIDIA has not said how much it is putting into the five startups, so treat the “$1 billion” figure circulating on social media as unconfirmed. The moves build on the £2 billion UK startup pledge NVIDIA made in September 2025.
The five startups NVIDIA is backing
In an announcement post dated October 13, NVIDIA said it had “new planned investments” in five companies. It didn’t disclose amounts, stakes or valuations, and Dealroom also reports that specific amounts have not been disclosed. Here is how NVIDIA describes each one:
| Startup | Base | What it does (per NVIDIA) |
|---|---|---|
| Boltz | London | Founded by MIT researchers; builds biomolecular AI models and agents that help scientists predict molecular structures and interactions |
| Foresight | London | Helps owners of major infrastructure projects, including hyperscale data centers, predict completion dates and reduce risk |
| Hiverge | Cambridge | Founded by researchers from Google DeepMind and the University of Cambridge; an AI “discovery engine” that writes and optimizes algorithms, for example for faster AI training and logistics planning |
| Prima Mente | London | An AI biology startup building biological foundation models |
| Riverlane | Cambridge | Quantum computing company building real-time error-correction hardware and software that works across all major qubit types |
NVIDIA’s official account summed up the evening with: “From new medicines to quantum computing, there’s plenty to build.” The company also said it is joining the Earthshot Prize as a Global Alliance Founding Partner, bringing compute and technical help to climate and sustainability innovators.
Riverlane is the most interesting bet
Riverlane stands out because it isn’t an AI company in the usual sense. It works on quantum error correction, the layer that keeps fragile quantum computers accurate enough to be useful. In a blog post on October 14, Riverlane said it is collaborating with NVIDIA on using AI and NVIDIA H100 GPUs to speed up decoder calibration, so error correction can keep pace as quantum hardware drifts. “As quantum systems scale, QEC becomes one of the world’s most demanding real-time computing challenges,” said founder and CEO Steve Brierley.
For NVIDIA, which already sells the GPUs that run AI, this is a hedge on what the next generation of computing looks like. It follows other bets we’ve covered, including NVIDIA putting up to $1 billion into AI coding startup Poolside.
The $250 million AI safety compute pledge
The bigger number this week came from a separate NVIDIA press release. The key details:
- Value: a compute donation worth $250 million over five years, delivered as $50 million in compute access each year. This is computing time, not cash.
- Focus: “agentic safety and security” research, meaning work on keeping autonomous AI agents secure, testable and under control.
- Who benefits: mostly the wider UK AI safety and security research community, with a portion going to the British Open-Ended Learning and Discovery Lab (BOLD) led by the University of Oxford, the Science of Fundamental AI Research Lab (SOFAIR) led by UCL, and Imperial College London, including robotics safety.
- How it’s delivered: through UK-based NVIDIA Cloud Partners with infrastructure hosted in the UK. NVIDIA says provider selection, technical architecture and commercial terms are still to be agreed.
- Research topics: secure agents, open-model security, real-world threat mitigation, secure sandboxes and safety benchmarks, including work using NVIDIA’s OpenShell runtime and Sentry reference design.
“AI capability and safety must advance together,” Huang said in the release. “With this $250 million commitment, NVIDIA will put accelerated computing in the hands of U.K. researchers to develop, test and strengthen safeguards for increasingly powerful AI.”
UK AI Minister Kanishka Narayan called the donation “a vote of confidence in our world-leading strength and expertise in AI research,” and said safety goals will be central to the UK’s G20 presidency. Jakob Foerster, founding director of BOLD, said “AI safety as an afterthought is no longer appropriate.”

UK companies already building on NVIDIA
NVIDIA used the moment to showcase British customers. The examples it listed include:
- Fuse Energy moving its customer AI onto in-house NVIDIA B300 Blackwell Ultra infrastructure, serving more than 450,000 UK households.
- LSEG working with NVIDIA on GPU-accelerated market analytics.
- Lloyds Banking Group building ATUM, a transaction foundation model, and Revolut scaling PRAGMA, a foundation model for banking event sequences.
- Starling developing a banking foundation model on Civo’s UK sovereign cloud, and NatWest collaborating on Nemotron Voice.
- Liverpool City Region building an NVIDIA-powered “City Brain” designed as a blueprint for other UK authorities.
- Locai Labs releasing Nemotron-Personas-UK, an open dataset of one million synthetic personas reflecting UK diversity.
NVIDIA also says more than 3,100 UK companies are part of its Inception startup program.
How this fits NVIDIA’s bigger UK push
This isn’t NVIDIA’s first big UK move. In September 2025, it announced a £2 billion commitment to the UK AI startup ecosystem, with venture firms Accel, Air Street Capital, Balderton, Hoxton Ventures and Phoenix Court joining in, targeting hubs such as London, Oxford, Cambridge and Manchester. NVIDIA says it has since backed UK companies including Basecamp Research, Synthesia and Wayve.
The strategy is consistent: invest in startups that run on NVIDIA’s stack, fund research that makes its hardware the default for new fields like agent safety and quantum, and build goodwill with governments that control AI regulation and data center permits. Next up, Huang delivers the GTC Berlin keynote on October 21 at 11 a.m. CEST, where more European announcements are likely.
The bottom line
NVIDIA’s latest London announcements are less about one giant check and more about reach. Five new startup bets span biology, infrastructure, algorithms and quantum, and a $250 million compute pledge puts NVIDIA hardware at the center of UK AI safety research. The exact size of the startup investments remains undisclosed, so be skeptical of any total you see quoted until NVIDIA confirms it.
