QumulusAI has expanded its Denver capacity by 1.2MW through a colocation deal that increases availability in the market.

QumulusAI, a neocloud, has signed a 1.2MW colocation agreement in Denver, Colorado.

The company has signed a five-year agreement, with automatic five-year renewal terms for the colocation capacity. The capacity is expected to be operational from Q1 2027 and expands QumulusAI's existing footprint in Denver.

The lease has been funded by cash generated from the company's operations.

"We take small blocks of power that already exist and move fast to bring them online. Speed is the point," said Michael Maniscalco, CEO of QumulusAI. "It gets customers compute sooner, and it shortens the time between deploying capacity and earning on it."

In June of this year, the company revealed it had secured $124 million in customer commitments with "open access AI cloud" Hyperbolic and another unnamed AI inference platform.

The company offers capacity from colocation data centers, with operations across the US in Atlanta, Kansas City, Philadelphia, Denver, and Brooklyn.

In February 2026, the company received approval for a modular data center in Denton, Texas. The project is planned for around four acres of land near Western Boulevard and Jim Christal Road and will operate near the RD Wells substation. It is hoped to have around 20MW of capacity. The land is being leased from the city for around $20,000 annually over the next ten years, as agreed in August 2024.

Colocation providers in Denver include Flexential, Colorado Colo, Iron Mountain, Equinix, and H5 Data Centers, among others.
