Vonage

Major cloud communications platform provider and CPaaS vendor, now operating as an Ericsson subsidiary

Vonage is a cloud communications platform provider that offers unified communications, contact center, and communications APIs for businesses. Founded in 2001 as a consumer VoIP service, Vonage evolved into a business communications platform provider, particularly known for its Communications Platform as a Service (CPaaS) offerings through the Vonage API Platform. The company enables businesses to embed voice, messaging, video, and verification capabilities into their applications. In 2022, Vonage was acquired by Ericsson for $6.2 billion, becoming a wholly-owned subsidiary. The acquisition positioned Vonage as a key component of Ericsson's enterprise strategy, combining Vonage's cloud communications capabilities with Ericsson's global network infrastructure. While Vonage is not strictly an AdTech company, its communications APIs and customer engagement platforms are used by various industries including marketing, customer service, and sales teams for customer communication and engagement purposes. Vonage serves businesses of all sizes, from small businesses to large enterprises, across multiple industries. Its platform includes Vonage Business Communications (VBC) for unified communications, Vonage Contact Center (VCC) for customer service operations, and the Vonage Communications Platform for developers building custom communication solutions.
