About
Twilio is a San Francisco-based cloud communications platform — providing APIs for SMS, voice calls, WhatsApp, email, and video — enabling companies to embed communications capabilities directly into their applications without building telecommunications infrastructure. Listed on NYSE (NYSE: TWLO), Twilio was founded in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis and generated $4.17 billion in revenue in fiscal year 2024, serving 320,000+ active customer accounts including Airbnb, Uber, Netflix, and Walmart as the dominant developer-first communications API platform.
Enterprise CPaaS with owned carrier infrastructure for voice, SMS, and 911; Microsoft Teams and Zoom as customers competing with Twilio for carrier-grade cloud communications APIs.
About
Bandwidth is a cloud communications platform-as-a-service (CPaaS) company providing enterprise-grade voice, messaging, and emergency services APIs — enabling enterprises, software vendors, and UCaaS providers to build voice calling, SMS/MMS, and 911 services directly into their applications using Bandwidth's carrier-grade telecommunications infrastructure. Listed on NASDAQ (NASDAQ: BAND), Bandwidth is headquartered in Raleigh, North Carolina and generated approximately $600 million in annual revenue, serving major enterprises and software platforms including Microsoft (Teams Phone), Zoom, Google, RingCentral, and Cisco as customers.\n\nBandwidth's platform provides RESTful APIs for programmatic control of voice calls, text messaging, toll-free numbers, local phone number provisioning, and emergency 911 calling. Unlike aggregators that resell capacity from other carriers, Bandwidth owns its telecommunications network infrastructure — providing the direct carrier connectivity that gives enterprise customers more reliability, better quality, and compliance capabilities (E911 for emergency services, STIR/SHAKEN for call authentication). This carrier-of-record status positions Bandwidth as infrastructure for other cloud communication platforms rather than competing directly with UCaaS providers.\n\nIn 2025, Bandwidth competes with Twilio (the larger CPaaS provider by revenue), Vonage (Ericsson), and Sinch for API-driven communications infrastructure. Bandwidth's differentiation lies in its direct carrier infrastructure — while Twilio aggregates carrier capacity, Bandwidth's own network provides enterprise compliance capabilities and 911 infrastructure that software-only aggregators can't match. The enterprise focus on compliance-grade voice and emergency calling creates stickier relationships than commodity messaging volumes. The 2025 strategy focuses on growing its Microsoft Teams Direct Routing business, expanding international voice infrastructure, and building more AI-powered calling features including voice analytics and real-time transcription.
