Fractile was founded in 2022 and operates from two primary locations in London and Bristol.

UK AI hardware start-up Fractile is in talks to raise funding of around $600m at a pre-money valuation of $6.5bn, according to Bloomberg.

The new valuation is estimated at more than six times that of the company’s last funding round in May, when it raised $220m.

The new funding is set to be co-led by Lightspeed Venture Partners and Redpoint Ventures, with the possible involvement of Thrive Capital and Founders Fund, according to Bloomberg’s sources.

Fractile aims to enable the scaling of cheaper AI token processing for faster model reasoning by building hardware that offers “low latency and high throughput”, with its operations spanning “transistor-level circuit design up to cloud inference server logic”, according to the company.
