UK AI chips start-up Fractile raises $720m at $7bn valuation

UK AI chip start-up Fractile has secured a significant $720 million funding round, bringing its valuation to an impressive $7 billion. The company, founded in 2022 by Walter Goodwin, aims to develop faster inference hardware for agentic AI to tackle challenging problems. Fractile operates from London and Bristol, with previous hires in Taiwan and San Francisco.

The latest funding round, led by Thrive Capital, Lightspeed, Redpoint, and Founders Fund, has surpassed initial reports of a $250 million deal to sell chips to Anthropic in 2027. Goodwin revealed that the proceeds will be used to scale and optimise Fractile's hardware for agentic reasoning.

The UK government's Sovereign AI Venture Fund and the British Business Bank also participated in the raise, signifying the country's ambition to become a world leader in AI technology. This investment aims to strengthen Britain's sovereign capabilities in critical technologies and reduce dependence on overseas supply chains.

UK AI minister Kanishka Narayan praised Fractile for its "very best of British ambition," highlighting its blend of chip design, engineering, and AI expertise. He emphasized the importance of developing faster, cheaper, and more energy-efficient hardware to serve the British people, enhance public services, and create good jobs across the nation.
