UK-based Fractile Ltd. Completes $720 Million Series C Financing for AI Chips

en.Wedoany.com Reported - On November 11, UK-based AI chip company Fractile Ltd. announced the completion of a $720 million Series C financing round, reaching a post-investment valuation of $7 billion. The round was co-led by US-based Thrive Capital, Founders Fund, Lightspeed, and Redpoint, with participation from Google's investment arm CapitalG, BlackRock, DST Global, Balderton, as well as the UK Government's Sovereign AI Venture Capital Fund and the British Business Bank. The funds will be used to advance R&D in AI inference chips, accompanying computing systems, and software, and to support the company's launch of its first commercial chips and systems in 2027.

Founded in 2022 and headquartered in London and Bristol, UK, Fractile primarily develops specialized chips for inference tasks on large AI models. Unlike traditional AI accelerators that rely mainly on high-bandwidth memory (HBM) to connect processors, the company adopts an architecture that stacks dynamic random-access memory (DRAM) directly on top of logic compute chips, creating a tighter data transfer structure between compute units and memory units. Investors disclosed that this design can increase memory bandwidth while retaining substantial data storage capacity, specifically addressing the computational waiting issues caused by insufficient data transfer speeds during large-model inference.

The company adopts a full-stack R&D model spanning from chip design to system software, with operations covering processor architecture, memory systems, accompanying software, and machine learning research. Its technological focus is on increasing token generation speed during the AI model inference phase and reducing computational latency and energy consumption in long-context processing and continuous task execution. Unlike chips primarily designed for model training, Fractile focuses on developing inference processors for model deployment and actual operation, targeting AI model developers, cloud computing service providers, and large data center operators as its customers.

This financing round also received funding support from the UK government. The UK Sovereign AI Venture Capital Fund and the British Business Bank participated jointly in the investment. The UK government disclosed that this round exceeds £500 million, with the company valued at over £5 billion. The government's investment focus is on expanding the UK's domestic AI chip R&D and manufacturing capabilities and reducing dependence on overseas supply chains for critical computing hardware. Fractile previously announced plans to invest £100 million in its UK operations over the next three years to expand its existing operations in London and Bristol and to build a new hardware engineering facility in Bristol.
