British AI Chip Startup Fractile Raises $720 Million in Series C Funding
Fractile, a UK-based semiconductor startup, has secured $720 million in a Series C funding round to accelerate the development of purpose-built AI chips. The round was led by prominent venture capital firms including Thrive Capital, Founders Fund, Lightspeed Venture Partners, and Redpoint, with significant backing from Britain’s Sovereign AI Fund. The company's valuation is estimated to be between $5 billion and $7 billion. Fractile distinguishes itself through a full-stack approach that combines specialized hardware with a machine learning compiler designed to optimize Large Language Model (LLM) execution. Their technical innovation focuses on stacking DRAM directly onto chips to resolve the memory capacity versus speed tradeoff, a critical bottleneck for agentic AI. The company plans to ship its first chips and systems next year.
