About Bandwidth
Bandwidth sells communications APIs and the carrier services behind them. Its Universal Platform bundles voice, messaging, phone numbers, and insights tooling on one platform, and the company operates as a carrier itself — the site lists wholesale services like global SIP trunking, VoIP origination and termination, international long distance, and toll-free voice alongside its developer APIs. The API catalog covers voice, media streaming, SMS, MMS, RCS, an all-in-one messaging API, WebRTC, an authentication API, and an emergency calling API. Around those sit number tools: provisioning and management, porting, CNAM caller ID, call verification, number reputation management, authenticated branded calling, and campaign registration for messaging compliance. There's also a nomadic emergency service (Dynamic Location Routing) and a Voice Activation Agent listed under wholesale as agentic AI. Bandwidth integrates with Salesforce Contact Center, Microsoft Teams (Direct Routing and Operator Connect), Genesys Cloud CX, Webex Calling, Zoom Phone, Google Voice via SIP Link, Five9, and Pindrop. The site targets four buyer types — global 2000 enterprises, SaaS product builders, voice AI startups, and communications providers — with industry pages for retail, finance, healthcare, hospitality, insurance, and telecom. Developer documentation, a getting-started guide, and code samples live at dev.bandwidth.com. Pricing is described as volume-based and isn't published as flat rates; there's a pricing page and a coverage map on the main site. Support is split between U.S./Canada and global (the latter via a legacy Voxbone portal), with paid support plans — Bandwidth claims a >99% SLA response rate on support tickets. The company also runs an investor relations site (investors.bandwidth.com), which indicates it's publicly listed.
