Fractile raises $720M for British AI chip push

Fractile lands $720M from UK fund

British AI chip startup Fractile raised seven hundred twenty million dollars in Series C funding backed by Britain's Sovereign AI Fund to strengthen the UK's position in AI hardware.

Full-stack approach sets Fractile apart

Fractile combines custom AI chips with a machine learning compiler to maximize the speed at which large language models execute on its hardware, positioning itself as a frontier AI company.

Valuation tops five billion pounds

The round was led by Thrive Capital, Founders Fund, Lightspeed Venture Partners and Redpoint and valued Fractile at over five billion pounds, possibly seven billion dollars according to Financial Times and Reuters.

DRAM stacking solves memory tradeoff

Fractile's hardware design stacks DRAM on each chip to bypass the usual tradeoff between memory and capacity, addressing challenges posed by agentic AI requiring longer task chains without speed loss.

First chips shipping next year

CEO Walter Goodwin said in a LinkedIn post that the new funding will enable Fractile to ship its first chips and systems next year, though there is still a lot of work ahead.
