The UK government has launched Sovereign Artificial Intelligence, a national initiative designed to support domestic startups developing strategically important Artificial Intelligence technologies. The programme is framed as a state-backed effort to help founders start in Britain, scale quickly and compete globally, with the broader goal of keeping expertise, decision-making and economic value in the UK. Ministers positioned the scheme as a way to strengthen national security and economic prosperity while reducing dependence on foreign technology groups for critical Artificial Intelligence capabilities.
Sovereign Artificial Intelligence is backed by £500 million and is intended to operate more like a venture capital firm than a traditional public programme. The first equity investment will go to Callosum, a London-based company building software that helps different chip architectures work together more efficiently. A further 6 startups will receive access to the AI Research Resource (AIRR) supercomputer network: Prima Mente, Cosine, Cursive, Doubleword, Twig Bio and Odyssey. The government said each supported startup can receive up to 1 million GPU hours, and every company receiving investment will get visa decisions within a working day, plus access to an initial 10 cost-free visas for research and development talent.
The selected companies span a range of sectors where the UK sees strategic value. Prima Mente is applying Artificial Intelligence to biology and brain disease research, including Alzheimer’s and Parkinson’s. Cosine is focused on sovereign models and coding agents for defence, national security and regulated industries. Cursive is developing agents that improve through real-world use, while Doubleword provides inference infrastructure and governance tools for secure deployment. Twig Bio is building biological models for engineering biology and biomanufacturing, and Odyssey is developing world models with applications in defence, autonomous systems and simulation.
The government said Sovereign Artificial Intelligence is also currently in discussions with around 30 firms, over potential AIRR access. Alongside direct support, the unit is offering help with data access, procurement opportunities, product validation and routes into regulation. As part of Sovereign Artificial Intelligence’s £282 million offer to support cutting edge Artificial Intelligence startups with R&D, the unit is launching its first funding call to create new datasets and other assets that help firms move faster and build in the UK. The fund will continue assessing applications on a rolling basis and is set to allocate compute worth tens of millions of pounds to British startups over the course of the year.
