Decagon Agent Modules provide infrastructure for extending an AI agent beyond customer support into journeys such as lead qualification, onboarding, collections, and customer relationship growth. Teams define the business logic for each journey, with Duet helping translate their processes into agent behavior. Modules include journey-specific analytics and simulations, while Campaign Composer can sequence customer touchpoints across channels and time. A shared management layer supports separate team access and multiple agent instances, with memory carried across sessions, channels, and instances.
