UK AI chip startup Fractile raises $720 million
British AI chip startup Fractile raised $720 million in a funding round backed by the UK’s Sovereign AI Fund.
The company is developing chips and software to run large AI models faster and at lower cost.
Its funding round was led by four investment firms, and the UK government said Fractile’s valuation is above £5 billion; some reports put it at about $7 billion.
Fractile is one of several startups trying to build chips specifically for AI, as demand grows for the computing power needed to run these systems.
Its design stacks DRAM memory on each chip, aiming to ease limits on memory and capacity that can slow down complex AI tasks.
The new funding is intended to help Fractile ship its first chips and systems next year, though CEO Walter Goodwin said the company still has much work ahead.
