Sierra

What it does

Sierra builds support agents that can act — refund, reship, change an address — with guardrails and a route to a human when confidence drops. Conversations resolve inside the agent rather than being handed back as a draft.

Pricing is tied to resolved conversations instead of seats, which aligns incentives: they earn when the ticket closes without you. Enterprise onboarding, not self-serve.
