British AI chip startup Fractile raises $720 million before shipping its first chips

Fractile, a British startup building chips for running AI models, announced a $720 million Series C on November 11. The company told Reuters that Thrive Capital, Founders Fund, Lightspeed and Redpoint led the round. Backers also include the UK Sovereign AI Fund and the British Business Bank.

The UK government put the valuation above 5 billion pounds. Reuters reported a $7 billion valuation, citing a person involved in the deal.

TechCrunch reports that Fractile plans to stack DRAM on its chips to improve memory performance while retaining capacity. The government describes a broader approach spanning chips, software and machine learning research, aimed at faster, less costly AI.

CEO Walter Goodwin wrote on LinkedIn that the funding would support shipping the company's first chips and systems in 2027. He also acknowledged that substantial work remains. That is a development target, not confirmation that commercial hardware is available now.

The government says its backing is intended to strengthen domestic AI hardware capabilities and reduce reliance on overseas technology. For makers paying to run models, the useful test will be the performance and price of the eventual systems. The funding round alone does not establish that their model bills will fall.
