Whitefiber, Inc.
A maker of AI and high-performance computing infrastructure, WhiteFiber runs data centers and GPU cloud services that companies rent to train and run generative AI models. It grew out of crypto miner Bit Digital, which bought Montreal's Enovum Data Centers, renamed the business WhiteFiber in early 2025, and spun it off in an IPO that August. A fun twist: Enovum's founders had earlier built a web-hosting firm and the blockchain company Bitfarms.
