Fluidstack raises estimated £1.1b Series B for GPU cloud platform

Developers scaling large-language-model and other machine-learning projects can access high-performance infrastructure through Fluidstack Ltd, which has secured an estimated £1.1b in Series B funding. Based in London, the company operates a cloud platform that delivers on-demand processing power for AI training and inference. Its service provides access to thousands of GPUs, including NVIDIA H100 and A100 models, to help technical teams and enterprises manage their workloads.

Incorporated in 2017, the firm addresses the requirements of the specialized compute sector. Financial records for the year ending 31 December 2024 report a £556.4k loss and a headcount of 10 employees.

The investment follows the £659.6k raised across the entirety of 2025. The new shares bring the total funding secured during 2026 to £1.6b (allotted in July and filed in August).
