getfuse.com LinkedIn

Fuse Energy is a London-based, vertically integrated energy company combining utility-scale solar and battery storage development with real-time power trading and a consumer energy app. Its stack is unusually compute-heavy for a utility: CUDA, vLLM, TensorRT-LLM, Slurm, InfiniBand and NCCL point to in-house GPU infrastructure and LLM serving. A Postgres-to-ClickHouse migration signals a push toward high-volume analytics.
