UK chipmaker Fractile has raised around £540m in a funding round that values the company at more than £5bn, putting one of Britain’s most closely watched AI startups firmly in the global spotlight.
Based in Bristol and London, Fractile designs chips for AI inference – the stage where an AI model processes requests and produces an answer. The company was founded in 2022 by Oxford PhD Walter Goodwin.
Its approach keeps data directly on the chip, rather than repeatedly moving it between a processor and separate memory modules. Fractile says this could make large language models up to 100 times faster than existing hardware while cutting operating costs by 90 per cent.
From funding to data centres
The Series C round was led by Thrive Capital, Founders Fund, Lightspeed and Redpoint. It also included Alphabet’s CapitalG, the UK’s Sovereign AI fund, the British Business Bank, Shopify, Balderton, Dragoneer and BlackRock.
Fractile’s specialised chips are expected to be ready for data-centre deployment next year. The new investment follows a $220m Series B announced in May, which valued the business at around £820m.
The funding comes as the UK seeks to strengthen its position in AI hardware and reduce reliance on overseas supply chains for critical technology.
Why it matters for Britain
Fractile’s growth brings major investment into a British chip company with operations in Bristol and London. If its technology reaches data centres as planned, it could also support specialist engineering and AI jobs while helping develop more UK-based expertise in an important part of the AI industry.
