## Summary

NYSE-listed (RNG) cloud UCaaS platform with $2.4B revenue; 400K+ customers with Message-Video-Phone competing with Microsoft Teams Phone and Zoom for business communications platform.

## Company Overview

RingCentral is a Belmont, California-based cloud unified communications platform providing business phone systems, video conferencing, team messaging, and contact center (CCaaS) solutions to organizations replacing legacy PBX phone infrastructure. Listed on NYSE (NYSE: RNG), RingCentral generated $2.4 billion in revenue in fiscal year 2024 and serves 400,000+ customers globally from small businesses to large enterprises including BMW, Levi Strauss, and Sharp Electronics.

RingCentral's MVP (Message, Video, Phone) platform consolidates communications that traditionally required separate vendors — desk phones (Avaya, Cisco), video conferencing (Zoom, Webex), and team chat (Slack) — into a single application with unified administration, billing, and compliance. The RingCentral Contact Center (formerly Avaya's cloud contact center, integrated through a partnership) adds inbound and outbound call center capabilities with workforce management and customer experience analytics. The platform's 300+ API integrations (Salesforce, Microsoft Teams, Zendesk, Google Workspace) embed communications into business workflows.

In 2025, RingCentral (NYSE: RNG) competes in the unified communications and UCaaS market with Microsoft Teams (which includes integrated calling for Microsoft 365 customers, pressuring standalone UCaaS), Zoom (Zoom Phone expanding into full UCaaS), 8x8 (NYSE: EGHT), and Vonage Business (Ericsson) for business communications platform market share. Microsoft Teams Phone's aggressive pricing (bundled with Microsoft 365 for many enterprises) has been the primary competitive pressure on RingCentral's growth. RingCentral's response includes the RingCentral for Microsoft Teams integration (positioning RingCentral as the telecom layer within Teams), the RingCX contact center AI platform, and the AI-powered RingSense conversation intelligence. The 2025 strategy focuses on the enterprise mid-market, contact center expansion, and differentiating from Microsoft Teams through telecommunications reliability and compliance features.
