Overview
Fluidstack is an artificial intelligence infrastructure company that builds and operates large GPU clusters for model developers, research labs and enterprises. It began by aggregating idle compute from data centres and has since moved into developing dedicated gigawatt-scale sites, arranging the power, financing and construction alongside the clusters themselves, and it works with national governments and sovereign programmes as well as commercial labs. The company is headquartered in New York with a substantial London presence, and it competes with the specialist GPU cloud providers by taking on the energy and site development problem rather than only reselling capacity.
