Ten4

What Ten4 does

Ten4 is a US-based privately held telecom services provider founded in 1997–1998 and headquartered in Baltimore, MD, with a second office in Mt. Laurel, NJ serving the Philadelphia market. The company targets enterprise and mid-market organizations with complex, multi-location telecom environments, offering white-glove service rather than self-serve software. Its core capabilities span four pillars: hosted voice (Ten4 Voice), POTS line replacement (Ten4 AIR-LINE), consolidated billing and expense management (Ten4 Billing Plus, TCO), and analytics-driven telecom stewardship (Ten4 Platform powered by ForgeOS, Ten4 Portfolio, Ten4 Wireless, Ten4 Assist).

The underlying technology is a VoIP-based hosted voice platform with SIP trunking, Microsoft Teams integration, and CRM/helpdesk connectors (Salesforce, HubSpot, Zoho, Zendesk, ServiceNow). Ten4 AIR-LINE ships pre-configured devices that replace legacy copper lines for fire panels, elevators, fax, and security systems without trenching or build-out. Ten4 aggregates telecom inventory, billing, and usage across hundreds of carriers and thousands of lines, enabling vendor negotiation, error detection, and dispute management. AI-assisted features include voicemail transcription, live call transcription, intelligent IVR, sentiment analysis, and anomaly detection on call traffic.

Ten4 generates revenue through subscription-based hosted voice and AIR-LINE services plus managed-service fees for telecom expense management, billing consolidation, wireless optimization, and ongoing stewardship. Pricing is quote-based and tailored; the company offers free feasibility studies and billing reviews to land enterprise prospects via consultative field sales. Named customer wins include Select Medical/Concentra (3,000 sites), Education Affiliates (1,500 phones across 41 locations), BrightView (200+ sites), and Removery, with documented annual savings of $0.9M–$1.4M per large account. Leadership comprises CEO and founder Brooke Frank and President Scott Klemm, and the company operates with 1–10 employees, indicating a lean delivery model.
