Candu, Churn360, Churned, Avoma, Velaris, Apty, Cast - and SAP - are all chasing the same moment: when a customer quietly decides whether to stay. This is the software built to fight churn, and the AI agents now doing the fighting.

The London-and-Madrid startup landed as the only Visionary in Gartner's 2025 customer success ranking with a simple bet - that software should spot a shaky account before a human ever opens the health dashboard.
