AI concierge agents that resolve customer support end-to-end.

An enterprise platform for AI customer-support agents that handle issues across chat, email, and voice — not just answering questions but taking action to resolve them. Its Agent Operating Procedures (AOPs) let support teams encode handling logic in natural language while engineers keep code-level guardrails. Used by companies including Duolingo, Chime, and ClassPass to deflect a large share of support volume.

Pricing is outcome-based at $0.99 per successful resolution, with a 50-resolution monthly minimum.

Enterprise AI customer service agents across every channel.
