Decagon
Enterprise AI agents that resolve customer support end to end
Last reviewed 2026-06-18
Decagon builds AI customer support agents that handle conversations across chat, email, and voice, resolving common requests like answers, refunds, cancellations, and disputes without a human in the loop and escalating the rest. It targets large consumer and B2B brands that want to deflect high support volume while keeping a consistent brand voice.

Strengths
- +High autonomous resolution on common request types
- +True omnichannel: chat, email, and voice
- +Well funded and rapidly growing, low vendor-risk for enterprises
Limitations
- −Enterprise-only with no public self-serve pricing
- −Aimed at high-volume brands; overkill for very small teams
Overview
Decagon builds AI agents for customer support that aim to resolve customer conversations end to end rather than just suggest replies to human agents. It is positioned for large brands with high support volume.
What it does
The agent answers questions and completes actions such as refunds, cancellations, and disputes across chat, email, and voice, escalating to humans when a request falls outside its guardrails. Reported deflection at individual clients has been high (one published case study cites over 90% resolution without human intervention), though results vary by deployment.
Pricing
Enterprise, contact-sales. No public self-serve tier as of this review.
Best for / not for
Best for mid-market and enterprise brands deflecting high support volume across multiple channels. Not a fit for very small teams who need self-serve, low-cost tooling.
Traction
Decagon has raised a reported ~$481M total and was valued at roughly $4.5B in a January 2026 round led by Coatue and Index; revenue figures circulating publicly are third-party estimates, not audited.
Alternatives
Sierra and Intercom Fin compete in autonomous customer support.
