Intercom Fin
Pros
- Outcome-based pricing — you only pay when it actually resolves
- High resolution rates on documented, repetitive questions
- Runs on helpdesks other than Intercom
Cons
- $0.99 per resolution adds up at scale compared with seats
- Quality is capped by the quality of your help content
- Complex account-specific issues still need humans
Sierra
Pros
- Built to actually resolve tickets, not just deflect to a human
- Backed by real enterprise deployments with measurable resolution data
- Guardrails let businesses control exactly what the agent can and can't do
Cons
- Enterprise pricing and onboarding, not accessible to small businesses
- Still needs careful configuration to avoid over-promising to customers
- Complex order/billing integrations take real engineering time to wire up
Which one should you pick?
Pick Intercom Fin if
You have a decent help centre, a mid-sized support volume, and want to switch on an agent this week and pay only for what it resolves.
See Intercom Fin details →Pick Sierra if
You are a large consumer brand with complex integrations, need a deeply customised agent with voice as well as chat, and have the budget and timeline for an enterprise deployment.
See Sierra details →Bottom line
Fin for fast, outcome-priced deflection. Sierra for enterprise-grade custom agents. The honest test is whether you have a team to run a Sierra project; if not, Fin.
