UK AI chip startup Fractile raises $720 million Series C, backed by the government's Sovereign AI fund
The government says the round, worth over £500 million and joined by the British Business Bank, CapitalG, Lightspeed and Redpoint, values the London and Bristol firm at over £5 billion.
Why it matters
Fractile designs chips, software and machine-learning methods together to make AI inference faster, cheaper and more energy efficient, and the round is one of the largest for a British chip designer. The UK government frames its stake as a way to keep chip expertise, jobs and value in Britain and to reduce dependence on overseas supply chains, citing Arm as the precedent. Fractile says the Series C was led by Thrive Capital, Founders Fund, Lightspeed and Redpoint. Watch for when its first processors reach customers and how they compare with Nvidia's inference hardware.
