Overview

Decagon, founded in 2023, builds AI customer support agents aimed at consumer-facing brands handling high support volume, and the company has grown fast enough since launch to become one of the more frequently discussed newer names in this category among enterprise buyers evaluating AI-first support vendors.

Its agents are built to handle account-specific, sometimes complex customer issues autonomously, going past basic FAQ-answering into genuinely resolving account and order-related problems, with the underlying models fine-tuned per customer deployment rather than running one generic model across every client.

There's no free tier; Decagon sells through enterprise contracts. For a consumer brand evaluating newer, AI-first support vendors specifically built around large language models from day one, rather than platforms that evolved from older rules-based systems, Decagon represents that more recent generation of entrants.
