Agentic Index
Fin vs Sierra (2026)
Fin documents 11 of 14 and Sierra 11.5 and both charge for outcomes rather than seats, which makes this the closest comparison at the head of the category. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Fin is Intercom's standalone agent at 0.99 per resolution, with knowledge grounding, multichannel support, simulation based testing before deployment and enterprise handoff and escalation. Sierra is an enterprise conversational platform priced per resolution through sales. Identical coverage and a shared pricing philosophy, so this comes down to whether you want a published price you can model today or an enterprise engagement shaped around your organization.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Fin and Sierra are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 969 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Fin if
- A published 0.99 per resolution lets you model the cost before any sales conversation.
- Simulation based testing before deployment is how you de risk letting it answer customers.
- You already run Intercom, which makes this continuous rather than a migration.
Choose Sierra if
- Enterprise scale and a bespoke engagement is how your organization buys.
- You want the platform shaped around your workflows rather than adopting its shape.
- Independence from Intercom's wider suite matters for your stack.
