CyrusOne

David G. Duffield established CyrusOne in 2001 to provide secure, independent colocation services that allowed enterprises to connect with multiple telecommunications carriers without vendor lock-in. The company grew from a single facility into a global network of over 60 data centers spanning North America, Europe, and Asia by 2026. Its headquarters in Carrollton, Texas, anchors a strategy focused on high-density computing needs driven by artificial intelligence and hyperscale cloud providers.

A significant shift occurred in July 2026 when John Hatem assumed the role of Chief Executive Officer, replacing the previous leadership to accelerate growth in the AI sector. This transition coincides with preparations for an Initial Public Offering scheduled for 2027, aiming to capitalize on surging demand for digital infrastructure capacity. The firm recently secured a power agreement with Constellation Energy in February 2026 to support a new facility at the Freestone Energy Center in Texas.

Ownership rests with funds managed by Kohlberg Kravis Roberts (KKR) and Global Infrastructure Partners following a leveraged buyout in 2021. These private equity partners provided the capital necessary to expand operations while navigating regulatory challenges, such as a lawsuit filed in mid-2026 regarding a project near Springfield, Missouri. Despite these hurdles, the company maintains a carrier-neutral model that prioritizes flexibility for clients operating critical workloads across key technology hubs like Northern Virginia, London, Frankfurt, Tokyo, and Singapore.
