We’re investing in @fractile_ai to build the next generation of frontier AI chips.
Fractile is rethinking chip design from the ground up, bringing together hardware, software and machine learning.
Its ambition is to make increasingly capable AI models faster and cheaper to run, with global ambitions in AI hardware.

We’re delighted to announce that Fractile has raised $720M in a Series C led by @thrivecapital @foundersfund @lightspeedvp and @redpoint, with further participation by brilliant new and existing investors.
We’re investing in @TendrilsCompute as they rethink general-purpose chip design, developing a new processor architecture to make parallel computing practical for a much wider range of applications.
Sovereign AI retweeted
Tendrils has raised $30M led by @benchmark to rebuild general-purpose computing. @jaltma is joining our board.
At Tendrils, we believe that the future of general-purpose computing lies beyond legacy architectures for legacy software.

An ambitious state has backed British industrial science before.
With @UKSovereignAI’s investment in @potentialsci_, we are backing British ingenuity, jobs and medical innovation again! 🇬🇧

A deep, technical chat between Hatem and @CorinWagen: simulated data at coupled-cluster accuracy, lead optimisation, the hardware lottery and building in the UK with @uksovereignai.
Thanks @RowanSci for having us!
Yesterday, Potential Sciences came out of stealth to build a UK frontier lab for chemistry.
I spoke with Hatem Helal, Potential's CEO, about what they're building and why their simulation-first approach complements other AI-for-science teams.

AI for drug discovery has learned almost everything the existing experimental record can teach it. The next leap needs new data, and the laws of physics can supply it.
Potential Sciences is out of stealth to solve this problem, backed by @uksovereignai and @Twinpathvc.
We're investing in @potentialsci_, which is using AI to improve the data behind molecular AI.
Its technology rebuilds quantum chemistry software for GPUs, making highly accurate calculations possible at a reported 100x lower cost than traditional CPU implementations.

We’re excited to announce an additional £120m for Sovereign AI to back the future of AI in Britain.
An extra £60m to invest in the UK’s most promising AI companies, expanding into Physical and Industrial AI.
And £60m more for R&D procurement, backing innovation in areas such as AI security and AI for healthcare.
We want to help founders start and scale in Britain, and turn innovation into impact.

We’ve already backed some of the most ambitious AI companies being built in Britain.
From AI infrastructure and safety to science and new technologies, our portfolio spans some of the most exciting areas of AI, all with ambitious founders building from the UK.
Let’s hear from a few of the companies we’ve backed so far.
@CallosumAI | Augur | @Basecamp_Res
We’re announcing £1.57m of support for IMU Biosciences to help build a new population-scale immune dataset, in collaboration with UK Biobank.
This is the first award through Sovereign AI’s Strategic Assets Programme - designed to create datasets, infrastructure and capabilities that can unlock opportunities for a much wider group of British companies and researchers.
IMU’s wider project will profile 80,000 blood samples, creating a detailed new layer of immune data alongside UK Biobank’s existing genomic, clinical and lifestyle data.

We’re delighted to announce our investment in Augur.
Augur is building technology that can help security teams find information faster and respond sooner, with applications across public safety, serious crime and critical infrastructure.
Augur is already working on capability to prevent attacks by hostile states on Britain’s critical national infrastructure. They’re also partnering with @TfL to help identify and detect sexual offending on the transport network, behaviours that disproportionally impact women and girls.
We’re excited about the potential to help keep people safer, give investigators valuable time back, and spot threats before they become more serious. The Augur team is tackling an incredibly important problem and building the solution here in Britain.
Read our blog below for more information on Augur’s technology.

Our next round of compute applications is open.
Through the AI Research Resource (AIRR), successful applicants can access up to 1 million GPU hours on Isambard-AI, alongside cloud compute, to train models, accelerate research and scale breakthrough technologies.
