British startup Fractile has raised a $720 million Series C for its AI chips, backed by Britain's Sovereign AI Fund. Its CEO says the funding will let it ship its first chips and systems next year.
TechCrunch reports that Fractile, a British AI chip startup, raised a $720 million Series C round led by Thrive Capital, Founders Fund, Lightspeed Venture Partners and Redpoint, with backing from Britain's Sovereign AI Fund. The UK government put the valuation at "over £5 billion", while the Financial Times and a Reuters source reported a figure of roughly $7 billion. The government said the investment aims to give the UK a greater stake in the hardware that will underpin its future economy.
Fractile follows a full-stack strategy, combining its hardware with a machine learning compiler meant to maximize the speed at which large language models run on its chips. After a pivot, its design is built around DRAM stacked on top of each chip, which the company hopes will get around the usual trade-off between memory and capacity. TechCrunch notes that this trade-off has become more of a problem with the rise of agentic AI, as companies want large models to carry out longer chains of tasks without losing speed.
Such purpose-built chips are one of several avenues being explored to cut the cost of inference, meaning running AI models in production. Axelera, Etched and OLIX are among other well-funded startups in the field.
In a LinkedIn post, CEO Walter Goodwin wrote that "there is still a lot of work ahead" and that the new funding will let the company ship its first chips and systems next year.
