London‑based AI chip startup Fractile, founded by Walter Goodwin, is in talks to raise more than $200 million at a $1 billion valuation, the Financial Times reports.
The proposed round would be led in part by Accel, with the NATO Innovation Fund and Oxford Science Enterprises also reportedly in discussions. However, the deal has not yet been finalised and terms, including size and exact valuation, could still change.
As part of a growing cohort of UK‑based chipmakers, Fractile is betting that the next wave of AI computing will shift from raw training power toward faster, cheaper, and more efficient inference. As more companies prioritise inference efficiency, cost, and power, investors are turning to startups that build hardware specifically designed for those workloads rather than relying solely on NVIDIA’s traditional GPU stack.
Fractile is taking a distinct technical path, using static random‑access memory (SRAM) in its architecture to improve speed and reduce cost for AI inference. The company is also developing both hardware and software in tandem, with the goal of reducing the classic “memory‑bottleneck” by bringing compute and memory closer together.
The startup faces competition from Graphcore, Enfloba, and Tenstorrent, which are pushing specialised architectures designed to handle large‑scale models more efficiently than standard GPUs. At the same time, established players like NVIDIA and AMD continue to tune their chips and software stacks for inference‑centric workloads, while a new wave of Silicon Valley‑ and Asia‑based hardware startups are also targeting the same efficiency‑first niche.
Last month, the company announced a £100 million investment over the next three years to expand its operations in London and Bristol, including a new engineering facility dedicated to industrial‑grade hardware.
The expansion signals Fractile’s ambition to scale from a research‑oriented chip startup to a full‑stack AI infrastructure player, as the UK tries to build a domestic alternative to the current GPU‑centric AI value chain.
