Intercom Fin vs Sierra (2026)

Intercom Fin

by Fin

Sierra

by Sierra

Pros

• ✓Outcome-based billing at $0.99 per outcome, charged once per conversation, with a 76% average resolution rate that Fin reports across 12,000+ customers.
• ✓MCP on both sides: the official Intercom MCP server offers 14 tools for US and EU workspaces with setup guides for Claude and Cursor, and MCP connectors let Fin act in Stripe, Shopify, Linear and Zapier.
• ✓The trust center lists SOC 2 Type II, ISO 27001, ISO 27018, ISO 27701, ISO 42001, HDS, CSA STAR and AIUC-1, with a HIPAA attestation and a BAA available to every Fin workspace.

Limitations

• ⚠Fin on another helpdesk is bought through the sales team with a 50-outcome monthly minimum, and Fin Voice is priced on a custom plan.
• ⚠Inside the Intercom helpdesk, outcomes are billed on top of seats: $29, $85 or $132 per seat per month billed annually, or $39, $99 or $139 billed monthly.
• ⚠Fin's models are trained by default on de-identified data from past Fin interactions. Workspaces with a BAA, EU or AU hosted workspaces and customers previously granted an opt-out are excluded.

Pros

• ✓Co-founded by Bret Taylor, a former Salesforce co-CEO and OpenAI board chair, and Clay Bavor, an 18-year Google veteran who led Google Labs and Lens. Sierra has raised $1B+ at a $15.8B valuation and reports $150M+ ARR.
• ✓Outcome-based pricing charges per resolved interaction rather than per seat or conversation, so what a buyer pays tracks resolutions delivered rather than seats purchased.
• ✓Compliance covers FedRAMP High, SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR and CCPA, with named audit reports for SOC 2 and HIPAA available under NDA through the trust center.

Limitations

• ⚠Sierra publishes no pricing page, no rate card, no minimum commitment and no per-outcome rate. Every commercial term including the definition of a resolved outcome is negotiated directly.
• ⚠Deployment is sales-led with no self-serve signup. Published customer go-live timelines run from two to ten weeks, and integration changes route through Sierra's engineering team rather than self-service configuration.
• ⚠There is no connector marketplace and no pre-built integration library, verified against six candidate paths. The MCP route is scoped to ChatGPT Apps, so teams standardizing on another MCP client have no documented endpoint.
