GreenWeaver
Headquartered in London, United Kingdom
GreenWeaver is a UK-based sustainable cloud computing company launching in London in early 2026. It offers on-demand access to high-performance NVIDIA GPUs for AI, ML, and HPC workloads. What sets GreenWeaver apart is its innovative use of server heat: instead of wasting it, they recycle up to 90% to warm local homes through district heating. Where heat reuse isn’t possible, they rely on renewable energy, making their compute not just cheaper, but greener.
