RingCentral
Cloud phone and contact center software for businesses, built on old Avaya customer base.
RingCentral makes real money and keeps a large captive Avaya customer base, but its core phone business grows slowly while Microsoft, Amazon, and NICE fight over the AI contact center layer that is supposed to replace it.
RingCentral sells cloud-based phone systems and customer service software to businesses. It is hard to switch away from because companies have spent years setting up the system and training employees, but Microsoft is bundling its own phone system free inside Office 365, and Amazon is offering cheaper per-minute pricing instead of charging per seat, so customers are leaving. The question that matters most is whether RingCentral's new AI customer service business grows fast enough to make up for all the old phone customers who are switching to competitors like Microsoft, Amazon, and Salesforce-owned Genesys, or if the math falls apart before that happens.
RingCentral's subscription revenue growth rate versus UCaaS market CAGR (18-21%) over next two quarters. persistent gap below market growth confirms ongoing share loss.
