Published: 18 September 2026 · Updated: 18 September 2026 · Prices and figures verified: 18 September 2026 · By the ai-agents.reviews team

This page was researched and drafted with AI assistance from the sources listed on it. We have not run hands-on tests of these products. Method: [How we review](https://ai-agents.reviews/en-gb/how-we-review)

Decagon builds AI agents for chat, email and voice at large consumer, fintech and telecom brands. It publishes no prices and offers no trial. Procurement data puts the median contract at US$432,750 a year.

**Bottom line**

- **Best for:** Large enterprises with high volume and a six-figure budget
- **Not for:** Any team that wants to try before it buys
- **Price from:** est. US$105,000 per year
- **The catch:** No public prices, and the pricing most often observed by buyers is per conversation, so you may pay for conversations the AI does not resolve unless you negotiate otherwise.

## Pricing

Decagon publishes nothing. Vendr's procurement data shows a median contract of US$432,750 a year, ranging from US$105,000 to US$923,183; Vendr does not show its sample size. You will often see a "$50,000 platform fee" quoted online. We traced it only to competitors' blog posts and found no primary source, so we do not repeat it as fact.

## Claimed vs reported performance

| Reported figure | Source | Who says so |
| --- | --- | --- |
| 80% (deflection, not resolution) | Decagon AI, Inc. | Vendor claim |
| 70% | Chime | Named customer |
| 80% | Duolingo | Named customer |

The company has been quoted citing average deflection above 80%, with no published definition. Chime reports 70% resolution and a 60% cut in support costs; Duolingo is shown at 80% deflection. One detail worth knowing: Chime appears as a customer of both Decagon and Sierra, so logo lists do not imply exclusivity.

> **For buyers in the United Kingdom** The UK has no AI Act. An AI support agent is governed by the law you already know: UK GDPR and the Data Protection Act 2018, PECR for anything a chat widget stores on a device, and, for regulated financial firms, the FCA's Consumer Duty. Rules on automated decisions changed on 5 February 2026. [AI customer service agents and the law in the United Kingdom](https://ai-agents.reviews/en-gb/guides/ai-customer-service-agents-and-the-law)

## Verdict

Decagon is built for companies whose support volume justifies a contract in the hundreds of thousands of dollars and a roughly 6-week deployment. Its low score on access is a direct result of selling only through sales; judge it on a proof of value with your own tickets.
