Iren Limited
A Sydney-based operator of renewable-powered data centers that both mines Bitcoin and rents out cloud-based GPUs to companies training and running AI models. Founded in 2018 by brothers Daniel and William Roberts as Iris Energy, it renamed itself IREN in 2024 as it expanded beyond Bitcoin mining into AI cloud services. It deliberately builds its facilities next to cheap, underused renewable power sources—a strategy it calls "stranded energy"—with sites in Texas and British Columbia.
