What Decagon does

Decagon builds omnichannel AI customer service agents for large enterprises (Chime, Duolingo, ClassPass, American Airlines, Rippling), letting teams define agent behavior via natural-language 'Agent Operating Procedures' instead of code, with built-in testing and QA tools called Watchtower. It targets large support organizations wanting deep customization and observability into agent reasoning, not small self-serve teams. Founded in 2023, it sells exclusively through custom enterprise contracts with a platform fee plus usage-based resolution pricing.

What you get: Agent Operating Procedures (natural-language workflow definitions), Watchtower automated QA monitoring, Trace View / Agent Workbench for reasoning transparency, Omnichannel voice, chat and email deployment, Sub-second latency voice agent, A/B testing and experimentation tools, Customer intelligence analytics from conversation data.

Typical jobs: enterprise AI voice and chat agent for regulated industries; natural-language workflow builder for support automation; AI agent QA and reasoning transparency for compliance-heavy teams; replace legacy IVR with conversational AI.

Worth knowing: Pricing not disclosed on site, sales-led enterprise only; third-party procurement estimates range from ~$95K/year to ~$400K/year depending on volume and scope.

What users complain about: Early customers consistently flagged a lack of transparency into agent reasoning as a core issue, which pushed Decagon to build Trace View and Agent Workbench in response. (eesel AI / Quiq review roundups)

Pricing and plan limits

Verified August 2026
Plan Monthly Annual (per mo) Limits
Custom (Enterprise) not disclosed n/a ~$50,000/year baseline platform fee plus per-conversation or per-resolution usage pricing; third-party reports cite starting around $95K/year with median contracts near $400K/year

Where it wins

  • Agent Operating Procedures let support/ops teams define complex workflows in natural language rather than code
  • Watchtower QA and Trace View/Agent Workbench give visibility into why the agent made a given decision, addressing a common AI-agent trust gap
  • Strong reference customers (Chime, Duolingo, American Airlines, Rippling) across regulated and high-volume industries
  • Reported results include 70-80% deflection rates and up to 95% cost reduction at some customers
  • Sub-second latency voice support cited as a differentiator versus older IVR-style systems

Where it falls short

  • No public pricing at all; a ~$50K/year platform fee is just the baseline before usage costs are added
  • Reviewers describe it as trying to replace too much support surface too quickly, turning into a cost center for complex, multi-market products
  • Transparency into agent reasoning was a documented early complaint, only partially addressed by the later Trace View/Agent Workbench tools
  • Users report limited customizability in some areas despite the natural-language builder pitch
  • Enterprise-only sales motion with no trial or self-serve option shuts out smaller teams and slows evaluation
