Decagon vs Forethought (2026)

Decagon

by Decagon

Forethought

by Forethought AI

Pros

• ✓Agents run on Agent Operating Procedures that support teams write in natural language, with a supervisor model that checks for hallucinations before a response is sent and Watchtower QA reviewing every conversation, so behavior can change without engineering work.
• ✓Outcomes are published against named customers: Chime reports 70% chat and voice resolution, Duolingo an 80% deflection rate, Flashfood a 90%+ deflection rate and ClassPass a 95% cost reduction.
• ✓Zero-data retention is enforced with LLM providers including OpenAI and Anthropic, and the Trust Center lists SOC 2 Type II, ISO 27001:2022, HIPAA and PCI DSS 4.0.1, which suits regulated industries such as fintech and healthcare.

Limitations

• –No rates are published. Decagon offers per-conversation or per-resolution pricing, but both are quoted through sales, so cost cannot be compared with published-rate tools such as Intercom Fin without a scoping call.
• –Deployment is sales-led with an implementation team rather than self-serve, and G2 reviewers report a Time to Implement of 2 months, so it is not a fit for teams that need to launch in days.
• –Decagon states that its LLM providers retain no conversation data, but does not say whether customer conversations are used to train its own Chord voice model.

Pros

• ✓Four agents cover support: Solve resolves issues end to end, Triage classifies and routes tickets, Discover drafts articles for knowledge gaps, and QA scores 100% of human agent tickets.
• ✓Solve is trained on a customer's historical support data and works across chat, email, voice, Slack and a headless API, with support for 100+ languages.
• ✓Forethought's integrations page lists 70+ helpdesk, knowledge, connector and call center integrations, including Zendesk, Salesforce, ServiceNow, HubSpot and Amazon Connect.

Limitations

• –Pricing is quote-only on every plan, so a buyer cannot estimate cost without a sales conversation, and Forethought does not publish its contract terms.
• –Email, voice and Slack agents start on the Professional plan, the Solve API and knowledge gap detection are Enterprise features, and Multibrand and Discover are sold as add-ons.
• –Zendesk completed its acquisition of Forethought on March 26, 2026, and now offers it as Forethought AI Agents by Zendesk.
