Quick answer. Jibe is Google’s RCS platform — the backend infrastructure that powers RCS delivery for most carriers worldwide and for the Google Messages app. It handles the RCS network functions (registration, capability discovery, message routing, delivery) so carriers don’t each have to build their own, and it’s the system that RCS Business Messaging connects to. In practice, when a business sends RCS in most markets, it travels through Jibe to reach the recipient.
Jibe is why RCS scaled: rather than waiting for every operator to deploy its own RCS stack, carriers can use Google’s hosted platform, and US carriers have largely standardized on it via Google Messages. For developers, Jibe (through the RBM API or a provider) is the delivery layer beneath the agent.
