Telerivet
Telerivet is a cloud communications platform that lets organizations send, automate, and orchestrate messages across SMS, WhatsApp, Voice, USSD, Viber and more - in any market, including the places bigger providers ignore. Born from a Peace Corps insight in Tanzania that most people have a phone but not the internet, it now powers enterprises, governments, NGOs and universities across 150+ countries with a drag-and-drop rules engine, APIs, and a phone-as-gateway model that reaches customers where the network is thin.
