Led · Seed · Mar 2026
Founded in 2019, Calgary-based Infinidium Power Corp. is building modular AI infrastructure that eliminates traditional fan-based and liquid cooling systems, cutting grid dependency by roughly 60% and halving capital and operating costs versus conventional GPU clusters. The company’s patent-pending design reintegrates thermal airflow dynamics, enabling ultra-quiet, rapid deployments in vacant buildings without extensive permitting. Its platform targets dual revenue streams: high-density GPU compute and verified carbon credits generated from avoided energy consumption. Near-term plans include commissioning a 16-GPU NVIDIA H200 cluster, then scaling to a 48-GPU B200 system and ultimately multi-megawatt facilities. Infinidium is also crafting a global EPC and long-term operations services model to design, build, and manage turnkey AI sites worldwide. A proprietary orchestration layer is under development to optimize workload distribution, thermal efficiency, and carbon tracking across multiple sites. The current $1 million seed financing provides the capital for its first revenue-generating deployment and supports expansion of its EPC and off-grid data-center strategy.
