About

Bandwidth Inc. is a publicly traded (NASDAQ: BAND) communications platform-as-a-service (CPaaS) company that provides voice, messaging, and emergency services APIs to enterprises and other communications platforms. Founded in 1999 by David Morken and Henry Kaestner and headquartered in Raleigh, North Carolina, Bandwidth is one of the few CPaaS providers that owns and operates its own nationwide IP voice network. The company's infrastructure powers some of the largest communications platforms in the world, including serving as the underlying voice provider for companies like Microsoft Teams, Zoom, RingCentral, and Google.

Bandwidth's platform enables technology companies, UCaaS providers, CCaaS providers, and SaaS companies to embed voice calling, messaging, and 911 services into their own products through APIs. This makes Bandwidth a foundational white label infrastructure provider in the VoIP space. Partners use Bandwidth's APIs to provision phone numbers, manage SIP trunking, enable PSTN connectivity, send and receive SMS/MMS messages, and implement E911 services, all under their own brand. The company's Maestro intelligent call routing platform provides advanced call management capabilities.

As a Tier 1 carrier with its own CLEC (Competitive Local Exchange Carrier) licenses across all 50 US states, Bandwidth can offer network-level advantages including better call quality, lower latency, and more competitive pricing than providers who resell other carriers' infrastructure. The company went public in 2017 and has grown through acquisitions including Voxbone (expanding international coverage to 60+ countries) and Republic Wireless. Bandwidth serves enterprise clients directly and through its extensive partner ecosystem.

Bandwidth stands out as one of the few companies that owns and operates its own nationwide IP voice network, which gives it a significant edge in the white label VoIP space. As a Tier 1 carrier, they offer APIs and wholesale voice, messaging, and 911 services that power many of the biggest names in communications — including platforms like RingCentral, Zoom, and Microsoft Teams. Their developer-friendly APIs, competitive pricing, and direct network ownership translate to better call quality, lower latency, and more control for resellers and white label partners. The enterprise-grade reliability and regulatory compliance (including robust E911 support) make them a top-tier choice. The main drawback is that their platform is more suited for technically sophisticated partners rather than turnkey resellers looking for a plug-and-play solution.
