Side by side
Product attributes first, then what the sources establish for each customer workflow, then the industries they place each agent in. Open any claim to see its source, the date it was checked, and how to request a correction. Two agents are rarely documented to the same depth, so read a difference between the two columns as a difference in the public record before reading it as a difference in the products.
What this agent was judged by
The independent evidence behind these states comes mainly from practitioner forums and buyer reviews.States rest on 1 independent source across practitioner forums and buyer reviews. This is not the same yardstick for every agent, and that asymmetry is a known limitation.

|
| Channels | Decagon’s homepage lists chat, email and voice. SMS appears in its Curology customer story; confirm whether that channel is available for your proposed deployment.Vendor-reported
| Five9 markets both "Voice AI Agents" for automating routine customer interactions and "Digital AI Agents" providing personalized self-service via chatbots and social messaging.Vendor-reported
|
| Languages | The voice page advertises 70+ languages, automatic detection and switching. Confirm language support for each required channel and evaluate real conversations in those languages.Vendor-reported

|
| Target customer size | Decagon presents an enterprise offering and publishes customer stories for Chime, Notion and Rippling. That focus does not establish a minimum team size or exclude smaller deployments.Vendor-reported
| Five9 sells its bundles with "a minimum of 50 seats," positioning the AI agent capability at mid-market and enterprise contact centres rather than small teams.Vendor-reported
|
| Vendor-reported performance claims | Decagon reports a 65% reduction in support operating costs at Curology. This is a customer-specific vendor claim, not a resolution rate or a benchmark result; the page does not provide a common basis for cross-vendor comparison.Vendor-reported
| Unknown |
| Workflow evidenceBilling Illustrative scenario I was charged twice for the same order. Can you refund the extra payment? What to verify: Verify identity, inspect payment records, apply the refund policy, and confirm the payment-system result. If no authorized refund action is connected, hand off with the evidence. | Vendor-documented Illustrative evaluation: ask about a duplicate subscription charge. Verify access to the billing record, policy for credits and approvals, and whether the final action is recorded in the billing system. 1 cited claim for billing on DecagonDecagon’s technology page lists billing management, plan upgrades and account updates. It does not specify which billing operations are prebuilt for a particular payment or subscription system.Vendor-reported
| Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceOrders Illustrative scenario My order has not arrived. Where is it? What to verify: Retrieve the correct order and current carrier status. Distinguish a real tracking update from an estimate; do not invent a delivery date. | Vendor-documented Illustrative evaluation: a customer requests an address change after dispatch. Check the carrier and order-system state, then distinguish an allowed update from a request that needs human help. 1 cited claim for orders on DecagonDecagon’s Curology case study lists shipment-status checks, order replacements and shipment cancellation or postponement. These are specific examples from Curology’s configured service workflows.Vendor-reported
| Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceReturns Illustrative scenario I bought this 12 days ago and opened the box. Can I return it? What to verify: Check the actual return window, product exclusions, and order record. A policy answer and an executed return are different capabilities. | Vendor-documented Illustrative evaluation: return one item from a discounted bundle. Check eligibility, refund calculation, approval rules and the recorded return state. A refund request alone is not proof that a physical return was completed. 1 cited claim for returns on DecagonDecagon’s retail article describes answering return-eligibility questions and taking actions through systems such as Shopify while following company policies. It does not define a universal policy for refunds or exchanges.Vendor-reported
| Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceProduct questions Illustrative scenario Does this adapter work with my exact laptop model? What to verify: Use a current, approved compatibility source. Ask for the model when missing and distinguish documented compatibility from an assumption. | Vendor-documented Illustrative evaluation: ask whether a plan includes a feature and whether that feature works in a particular integration. Check that the answer uses current product documentation and distinguishes missing information from a confirmed limitation. 1 cited claim for product questions on DecagonDecagon’s technology offering describes surfacing relevant documentation during onboarding and troubleshooting. This supports a documented product-information workflow, not a measured accuracy result.Vendor-reported
| External report Five9 states that AI Knowledge lets teams "effortlessly upload knowledge articles, FAQ documents, and product information" and delivers contextually relevant answers directly to the customer. 2 cited claims for product questions on Five9Five9 states that AI Knowledge lets teams "effortlessly upload knowledge articles, FAQ documents, and product information" and delivers contextually relevant answers directly to the customer.Vendor-reported
CX Today reported that Five9's AI Agents use generative AI to "deliver contextual answers to queries without prior training" by drawing on trusted knowledge sources.Independent report
|
| Workflow evidenceAccount issues Illustrative scenario I lost access to my email. Change the address on my account. What to verify: Follow the approved identity-recovery process before accessing or changing account data. Escalate when identity cannot be verified. | Vendor-documented Illustrative evaluation: a user who cannot sign in requests an email-address change. Verify identity checks, permission boundaries and escalation when verification fails. 1 cited claim for account issues on DecagonDecagon’s financial-services page lists password resets, balance inquiries and dispute workflows. Those examples require a configured identity and account-access flow; the page does not prove that a given deployment implements it correctly.Vendor-reported
| Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceComplaints Illustrative scenario I have contacted you three times and the problem is still unresolved. What to verify: Recognize the repeat complaint, retain relevant history, and route it to the right team. Do not promise compensation outside the policy. | Vendor-documented Illustrative evaluation: a customer repeats an unresolved refund complaint. Check recognition of prior attempts, escalation rules and the promised follow-up. A sentiment flag alone does not resolve the issue. 1 cited claim for complaints on DecagonWatchtower documents identifying frustration and other conversation flags for team review. This is monitoring capability; the source does not demonstrate an agent completing a complaint remedy.Vendor-reported
| Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceHuman handoff Illustrative scenario Please connect me to a person who can approve this exception. What to verify: Transfer to an available team with the conversation and relevant records. Outside working hours, explain the actual follow-up path rather than promise immediate contact. | External report Illustrative evaluation: request a human after an unsuccessful troubleshooting step. Check queue routing, transcript transfer, repeated questions and the offline fallback. 2 cited claims for human handoff on DecagonDecagon documents live-chat escalation, email handoff and voice transfer to human agents.Vendor-reported
Krishan Y.’s August 12, 2026 review says their team can step in when human attention is needed. This corroborates takeover in one self-reported deployment, without measuring routing accuracy or waiting time.Independent report
| External report Five9 states that "when escalation is needed, full conversation context transfers instantly to a live agent, so customers never start over." 2 cited claims for human handoff on Five9Five9 states that "when escalation is needed, full conversation context transfers instantly to a live agent, so customers never start over."Vendor-reported
CX Today reported that with Five9 AI Agents, "contact centers can add guardrails to ensure these conversations still pass through to a live agent" when needed.Independent report
|
| Workflow evidenceSmall businesses Illustrative scenario A two-person support team wants to launch without a dedicated engineer. What to verify: Validate setup effort, existing help-desk support, required integrations, and ongoing maintenance. A small customer's story alone does not establish suitability for every small business. | Not established The reviewed sources do not establish suitability for every small team. Illustrative buying scenario: a two-person support team needs one channel and basic FAQ answers. Ask what setup, integration access and ongoing maintenance that scope requires. No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. | Caveat documented The 50-seat minimum applies to the underlying platform bundles rather than to the AI agent add-on in isolation, but it is the entry condition for using the capability. 1 cited claim for small businesses on Five9Five9's pricing page states that its bundles are "per concurrent user and usage-based pricing may apply, with a minimum of 50 seats," with AI Agents sold as an add-on above that floor.Vendor-reported
|
| Workflow evidenceMid-market Illustrative scenario A growing support team needs separate queues and connected order and account systems. What to verify: Validate routing, permissions, integration ownership, and handling of each team's policies in the intended configuration. | Not established Enterprise marketing does not exclude mid-market use. Illustrative buying scenario: a growing subscription business needs account updates and refunds. Confirm the specific connectors, implementation effort and responsibility for maintaining policies. No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. | Not established No supporting source is recorded here. Validate it with the vendor; absence of evidence does not establish a missing capability. |
| Workflow evidenceEnterprise Illustrative scenario A multi-brand support organization needs controlled access across regional teams. What to verify: Validate data boundaries, audit records, escalation ownership, and the specific deployment requirements. A vendor's enterprise positioning is not proof of these controls. | Vendor-documented Illustrative buying scenario: several brands share a support operation but use different policies. Evaluate permissions, policy separation, reporting and escalation under that actual structure. 1 cited claim for enterprise on DecagonDecagon publishes customer stories for companies including Chime, Notion and Rippling. These are vendor-published examples of enterprise use, not independent confirmation of every security, scale or workflow requirement.Vendor-reported
| External report Five9 positions AI Agents for enterprises, stating customers "deploy at enterprise scale with multi-agent systems, fast natural-language design, and full lifecycle control on one platform." 2 cited claims for enterprise on Five9Five9 positions AI Agents for enterprises, stating customers "deploy at enterprise scale with multi-agent systems, fast natural-language design, and full lifecycle control on one platform."Vendor-reported
CX Today reported that Five9 launched its AI Agents alongside an observability and governance layer covering hallucination detection, prompt-injection detection and completeness scoring with human oversight retained.Independent report

| Industry evidenceRetail and e-commerce | Vendor-documented Decagon publishes a retail offering describing order and return actions through systems such as Shopify. The source is the vendor's own; it names no retailer and reports no outcome. 1 cited claim for retail and e-commerce on DecagonDecagon’s retail article describes answering return-eligibility questions and taking actions through systems such as Shopify while following company policies.
