Forethought
- +Multi-agent coverage of the whole support workflow: resolution, triage, assist, discovery, and QA
- +Autoflows resolves end to end by reasoning over policies in natural language, not brittle decision trees
- +Layers onto existing helpdesks (Zendesk, Salesforce, Intercom) rather than replacing them
- -No public pricing; reported deals carry a ticket-volume minimum and run into the tens to low-hundreds of thousands per year
- -Agents are priced separately, so a full suite (Solve + Triage + Assist + Discover + QA) stacks up
Sierra
- +Strong founding team and enterprise traction
- +Voice and chat in one platform
- +Emphasis on guardrails and measurement
- -Enterprise-only, contact-sales
- -Less suited to small or self-serve teams
