Why teams look for a Fin alternative
Fin is a capable support agent with a clear published price. Teams look elsewhere for three reasons:
- Cost at volume. At $0.99 per outcome, a team resolving 50,000 conversations a month pays about $49,500 a month before Intercom seats.
- Ownership changed. Intercom renamed itself Fin in May 2026, and Salesforce completed its purchase in September 2026. Teams on other CRMs want a roadmap that does not depend on one suite.
- Scope. Fin answers and resolves support conversations. Enterprises want the same platform to run internal work and build the software around support.
The best Intercom Fin alternatives, ranked
1. SPIRITT: the enterprise choice for customer agents and AI across the business
Best for: large enterprises up to Fortune 500 that want customer experience agents and AI that runs the rest of the business.
Best capabilities. SPIRITT does the job people buy Fin for. It runs branded customer agents on voice, WhatsApp, SMS, web chat and email, reads your help center and past tickets, acts in your systems to refund, rebook or update records, and escalates to a human with full context. It buys phone numbers and runs an AI call center that answers, books appointments and hands off. Beyond support, its agents are more ambitious and more autonomous: they pursue long-running goals and plan, code, deploy and operate systems across research, sales, marketing, operations and engineering, with shared context. SPIRITT is a state-of-the-art coding agent, uses computer use for systems without an API, and composes Claude, GPT, Gemini, Grok, Kimi, DeepSeek, Qwen and its own Kay models within each task. Composing the best of every lab beats any single-lab subset.
Best trust: try it yourself first, no black box. Fin also has a trial, so test both on the same tickets. SPIRITT's self-serve version already handles more than a support-only agent, and SPIRITT Enterprise is more robust still. You see every step, plan, tool call and change; your agents and data live in your own workspace or cloud; and Read, Write and Destructive rules, single-use approvals, audit logs, SSO, SCIM, budgets, bring-your-own-cloud and air-gapped deployment keep it governed.
Best deployment. Top-tier forward-deployed engineers work with your teams, joined by certified partners with decades of enterprise integration experience on complex, heavy deployments, with multi-market rollout and localization. See Enterprise.

4. Ada: best for mid-market support teams on annual contracts
Ada runs AI agents for chat, voice and email with a reasoning engine and reporting. Pricing is custom; its AgentExchange listing shows a $30,000-a-year floor and an AWS listing quotes $0.55 per conversation on a 12-month contract (October 2026).
5. PolyAI: best for voice-first contact centers
PolyAI focuses on enterprise phone support with natural voice agents. Pricing is by quote. Choose it if the phone channel is the whole problem.
How to choose a Fin alternative
- Model your volume. Multiply monthly resolutions by $0.99 and add seats, then compare with a custom quote or credits.
- Check your help desk. Fin runs best inside Intercom. SPIRITT connects to the help desk and CRM you already use.
- Scope of the rollout. Fin, Sierra, Decagon, Ada and PolyAI focus on customer experience. SPIRITT covers customer experience plus internal work and software.
- Deployment capacity. Ask who staffs the rollout: forward-deployed engineers, certified partners and their record with complex integrations.
