QumulusAI is a cloud infrastructure company that provides GPU-powered compute capacity for artificial intelligence (AI) and high-performance computing (HPC) workloads. The company provides infrastructure for machine learning teams, AI startups, and research institutions to train models and run inference. QumulusAI targets small and mid-market developers who require flexible, fast-to-deploy capacity rather than the large-scale, standardized environments offered by hyperscalers. The business operates through two primary channels: a marketplace partnership with RunPod, which facilitates most of the company's GPUaaS sales, and a direct enterprise sales team for customers needing custom configurations. While QumulusAI maintains a legacy bitcoin mining and hosting segment, it is actively transitioning power capacity and capital from blockchain operations to its HPC business. The company's growth strategy focuses on expanding its fleet of NVIDIA GPUs and repurposing grid power from existing blockchain sites for HPC use. The company generates revenue by renting GPU capacity on either a usage or contractual basis, while operating costs include colocation fees, electricity, and equipment leases. To fund expansion, QumulusAI uses a mix of debt, convertible notes, and a decentralized finance protocol that tokenizes GPU assets to raise capital.
