Decagon

Decagon builds and scales AI customer service agents for enterprises including Chime, Duolingo, and American Airlines, handling voice, chat, and email through one unified intelligence layer rather than separate bots per channel. Its "Agent Operating Procedures" (AOPs) let teams define agent behavior in natural language rather than complex code, testing and optimization tools include A/B testing and quality-assurance simulations, "Watchtower" provides continuous AI quality monitoring, and "voice of the customer" analytics surface patterns across interactions. Documented customer results include 70% chat/voice resolution and 80% deflection rates. No pricing is published; access requires requesting a demo, typical for enterprise customer-service AI sold to large support organizations. Good fit for an enterprise support organization that wants one AI intelligence layer handling voice, chat, and email consistently, with formal quality monitoring built in rather than bolted on.
