QumulusAI Raises $45M in Convertible Notes to Fuel GPU and Data Center Expansion
AI cloud startup QumulusAI has secured a $45 million convertible note facility to accelerate its data center infrastructure buildout and GPU procurement, signaling continued momentum in the race to meet surging enterprise demand for artificial intelligence compute capacity. The funding, led by ATW Partners with an initial $15 million already provided, is designed to give the company financial flexibility as it executes an aggressive deployment roadmap for 2026.
The capital injection will support the procurement of more than 21,000 Nvidia Blackwell GPUs this year, a significant scaling effort aimed at addressing what the company describes as a market frustrated by reactive procurement processes and broker-driven delays. “In a market where enterprises are tired of reactive procurement and broker-driven delays, the financial flexibility that ATW Partners has provided is a genuine competitive advantage – one that is enabling us to transform how enterprises access the GPU-powered cloud infrastructure they need for production AI,” said Patrick Gahan, SVP of capital markets at QumulusAI. “We’re building at a pace and scale that the demand curve requires, and this capital is what makes that possible.”
This latest convertible note builds on a much larger $500 million blockchain-backed facility secured by QumulusAI in October 2025, which was arranged by Permian Labs and distributed via the USD.AI blockchain-based credit protocol. Together, these funding mechanisms underscore the company’s reliance on alternative financing structures to scale quickly in a capital-intensive sector.
Founded in 2019, QumulusAI operates as a GPU cloud provider and has already secured capacity across colocation facilities in Atlanta, Kansas City, Philadelphia, Denver, and Brooklyn. In February 2026, the company received approval for a modular data center in Denton, Texas, planned for roughly four acres of land near Western Boulevard and Jim Christal Road, adjacent to the RD Wells substation. The project is expected to deliver around 20MW of capacity, with the land leased from the city for approximately $20,000 annually over the next ten years, as agreed in August 2024.
Details on QumulusAI’s broader data center footprint remain limited, but the company states it will primarily use prefabricated data centers and aims to achieve a power usage effectiveness (PUE) of 1.1. It also intends to eventually secure access to 100MW of behind-the-meter natural gas to support its expanding infrastructure. Currently, QumulusAI offers access to Nvidia B200, H200, and H100 GPUs through its HPC cloud, positioning itself as a competitor in the increasingly crowded AI cloud market.
