What Granite Telecommunications does

Granite Telecommunications, LLC is a privately held competitive communications carrier founded in 2002 and headquartered in Quincy, Massachusetts, with 2,250+ employees across the headquarters and 11 regional offices nationwide. The company delivers managed voice, data, mobile, cloud, and security services through a single point of contact with consolidated invoicing across all of a customer's locations, managing 1.75 million voice and data lines at more than 650,000 locations and serving more than two-thirds of the Fortune 100 along with U.S. federal agencies, state and local entities, healthcare systems, real estate operators, and energy customers.

Granite's product architecture is organized as platform-plus-modules. Granite360, launched January 2025, is the unified service management layer integrating TechExpress for field-service dispatch, NOCExpress for continuous monitoring with ServiceNow ticketing, and AccessExpress for on-demand network sourcing. Granite Labs develops differentiated innovations: edgeboot (an AI-driven, patented managed network appliance for autonomous remediation, U.S. Patent No. 11,962,458 B2), Granite EPIK (a patented Managed Facilities-based Voice Network POTS replacement solution patented under Nos. 10,986,555 B1 and 11,743,797 B1), FlexEdge (a universal CPE consolidating multiple network functions), and Greenix (an AI-driven low-code workflow editor patented December 2024).

The company reports $1.85 billion in annual revenue and earns primarily through subscription managed services priced against SLAs, with predictable monthly billing for multilocation rollouts. Go-to-market combines a direct enterprise sales force targeting Fortune 100 and federal buyers with a Granite Channels program of technology advisors, MSPs, and VARs that has grown to more than $500 million in annual partner revenue on monthly residual commissions. Granite is one of nine prime contractors on the GSA $50 billion Enterprise Infrastructure Solutions contract, holds renewed NIST 800-53 ATO, and complies with HIPAA and PCI DSS for healthcare and payment deployments. Reported disclosed revenue is approximately $1.85 billion across 2024-2025 sources, with the Granite Channels program independently exceeding $500 million annually.
