NOTES

## Field notes

[Sierra](https://www.agentlist.io/systems/sierra)

High-volume consumer support orgs that want a branded agent resolving tickets end-to-end, not deflecting them.

Caveat — Enterprise-only and enterprise-priced; getting an agent to act safely inside order/account systems is an implementation project, not a toggle.
