What Coresite does
CoreSite is a U.S.-based carrier-neutral colocation and interconnection platform operating 30+ owned-and-operated data centers across 11 strategic markets (West, Central, Northeast, Mid-Atlantic, Southeast), totaling more than 4.8 million square feet. Its portfolio spans three core product lines: Colocation (cabinets, private cages, private suites, Remote Hands, Move-In Assistance), Interconnection (Open Cloud Exchange Layer 2 Ethernet Virtual Circuits, Any2Exchange peering, Blended IP, cross-connects, inter-site connectivity), and Cloud Networking (native private connectivity to AWS Direct Connect at 400G, Azure ExpressRoute, Google Cloud Interconnect, Oracle FastConnect). The Open Cloud Exchange anchors a network of 44,000+ customer interconnection points that delivers up to 70% data egress cost savings versus public internet transfers.
The company monetizes primarily through recurring subscription revenue on multi-year contracts for space, power, cooling, and cross-connects, supplemented by Remote Hands professional services. Pricing is quote-based and not publicly disclosed; sales run through direct enterprise field sales augmented by a channel partner program (resellers, agents, technology alliances) and the CoreSite Marketplace ecosystem. Customer segments are diversified across Financial Services, AI/ML platforms, Healthcare, Government, Media, Network Providers, Retail, Software/SaaS, Higher Education, and Cloud Service Providers, with named logos including Wayfair, Dropbox, Zoom, Red Hat, NVIDIA, AT&T, Zscaler, Synopsys, Backblaze, and Boingo.
Founded in 2001 and headquartered in Denver, Colorado, CoreSite has 251-500 employees and operates as a wholly-owned subsidiary of American Tower Corporation following the 2021 $10.4 billion acquisition. Stonepeak holds approximately 36% ownership of the data center segment after a $570 million investment in October 2022 that brought total commitment to roughly $3.07 billion. The company has earned Gartner Market Guide recognition (2025) as a Representative Vendor for Data Center Colocation, NVIDIA DGX Ready data center partner status, and Google Gold Verified Peering Provider status. Strategic priorities include high-density AI-ready infrastructure (GPU deployments, liquid cooling via OptiCool), cloud onramp upgrades (400G connectivity), and ecosystem expansion (Community IX exchanges in Miami and Northern Virginia).
