Britain’s Fractile gets $720m round to advance its AI chips race, TechCrunch reports
A major funding round
Fractile’s $720 million Series C places the British startup among the best-funded companies pursuing purpose-built AI chips. Britain’s Sovereign AI Fund backed the round, while Thrive Capital, Founders Fund, Lightspeed Venture Partners and Redpoint led it.
The British government said the company was valued at over £5 billion. The Financial Times and a Reuters source reported a valuation of about $7 billion. These reported figures use different currencies, and the article does not reconcile them.
Chips and software together
Fractile is taking a full-stack approach, pairing its hardware with a machine learning compiler designed to maximize the speed of large language models running on its chips. The company presents itself as a frontier AI company.
Its hardware design is a key differentiator. After a pivot, Fractile’s approach centers on DRAM stacked on each chip, with the aim of easing the usual tradeoff between memory and capacity.
Why inference costs matter
Purpose-built AI chips are among several approaches being explored to lower the cost of inference: running increasingly demanding AI models in production. Fractile is competing with companies including Axelera, Etched and OLIX.
The memory tradeoff has grown more challenging as companies use agentic AI for longer sequences of tasks with large models, while seeking to preserve speed. Compute capacity is struggling to keep pace, although AI chips remain limited in availability.
