With $720M round, Britain’s Fractile gets a leg up in the race for AI chips

British AI chip startup Fractile has secured a substantial $720 million Series C funding round, backed by Britain’s Sovereign AI Fund. The government aims to give the U.K. a stronger presence in the hardware driving its future economy, positioning Fractile among the highest-funded players in the development of specialized AI chips. Competitors like Axelera, Etched, and OLIX have raised comparable sums, reflecting the growing interest in the arena.

Fractile seeks to differentiate itself through a comprehensive strategy that includes not just hardware but also a machine learning compiler to boost the execution speed of large language models (LLMs) on its chips. The company is positioned as a frontier AI enterprise, and the Thrive Capital, Founders Fund, Lightspeed Venture Partners, and Redpoint led round was priced at an estimated valuation of over £5 billion, potentially $7 billion.

The startup's primary innovation lies in its hardware design, which focuses on stacked dynamic random-access memory (DRAM) on each chip. This approach aims to overcome the typical tradeoff between memory capacity and speed, a growing challenge as companies pursue longer chains of tasks with large language models in pursuit of speed.

While the hardware is promising, the company acknowledges that significant work remains ahead. Fractile CEO Walter Goodwin emphasized in a LinkedIn post that the new funding will help the startup ship its first chips and systems next year.
