About Decagon

Decagon is an enterprise platform for building and running AI agents that handle customer service. Agents work over chat, email and voice, and the company describes its aim as treating every customer as if they were the only one.

Teams define how an agent should work with Agent Operating Procedures, which are written in natural language, and can test them with simulations at scale before release. Live experiments compare versions, analytics and insights show how conversations perform, and Watchtower provides always-on quality assurance. The platform also suggests knowledge to add and connects to a company's own tools so agents can take actions.

Decagon does not publish prices and invites visitors to book a demo or contact sales. Funding reports in 2026 put its valuation at several billion dollars, and secondary sources describe per resolution billing, which is not stated on the company's site.

Our take

Good for
large companies that want AI agents handling customer chat, email and voice on top of their existing helpdesk.
Skip it if
you are a small business that wants a self-serve tool with a public price.
The catch
pricing is not published and is quoted per deal, and per-conversation billing can charge for conversations that still end with a person.

Checked . Plans and limits change, so confirm them on the vendor's site before you buy.
