Submer Group connects independent specialist companies across the AI infrastructure stack to close the gap between AI ambition and AI reality. Built on a decade of infrastructure engineering and now spanning from land and power to cloud and edge, it is a house of independent companies, each a leader in its own layer, with its own standards and accountability, connected so that expertise compounds across the stack. The group is built to address the structural constraints of AI infrastructure, namely power availability, thermal density, deployment speed and data sovereignty, enabling AI to be deployed efficiently and at scale. Its companies include Rubix Data Centers, which develops and operates AI-ready hyperscale data centers, and Radian Arc, whose InferX platform delivers GPU-as-a-Service, placing AI compute where it creates value. The group has deployed 500 MW+ of liquid-cooled infrastructure, holds 8 GW+ of powered land across the Americas, EMEA and APAC, and runs 2,000+ GPUs live across telecom. Founded in Barcelona in 2015, the group operates globally, with hubs in Houston and Taipei.
