The best alternatives to Sierra are Decagon, its closest rival, Ada for a lower and better-documented price, and Agentforce if your service already runs on Salesforce.
Teams look beyond Sierra mainly because nothing about its price, hosting or integrations can be checked without a sales process.
Why teams look beyond Sierra
- You need to see a price, a hosting region or a connector list before engaging sales.
- The billable outcome is defined per contract, and you want a standard definition.
- You do not need a bespoke, vendor-managed build.
The alternatives, ranked
Intercom Fin

Fin is the AI agent from the company formerly called Intercom, which renamed itself Fin in May 2026. It runs inside the Intercom helpdesk or on top of another one, charges $0.99 per outcome, and documents more about its pricing, languages and certifications than any other product we reviewed.
The catch: Customer silence for 24 hours is billed as a resolution, and so is a handoff to a human that you configured. Salesforce has agreed to buy the company.
Ada
Mid-market and enterprise teams that want an agent on top of their current helpdesk7.4- Price from
- est. $36,079 per year
- Pricing model
- Quote only
- Works on your existing helpdesk
- Yes
- Self-serve sign-up
- No
Ada is a Toronto company whose agent works across messaging, email and voice on top of the helpdesk you already have. It sells by quote, but it is the one enterprise vendor with substantial procurement data: a median contract of $72,000 a year across 114 purchases.
The catch: Ada's own AI decides which conversations count as billable resolutions, and the contract allows the count to be calculated from a sampled rate.
Salesforce Agentforce
Organizations already committed to Salesforce Service Cloud5.9- Price from
- $2 per conversation
- Pricing model
- Mixed
- Works on your existing helpdesk
- Requires Salesforce
- Self-serve sign-up
- No
Agentforce is Salesforce's AI agent platform for Service Cloud. It acts directly on CRM data and offers more pricing models than any rival: per conversation, per action with Flex Credits, per user, and since July 2026 per resolution with Help Agent.
The catch: The $2 per conversation plan bills whether or not the issue is resolved, and the pricing has changed repeatedly.
Decagon
Large enterprises with high volume and a six-figure budget5.8- Price from
- est. $105,000 per year
- Pricing model
- Quote only
- Works on your existing helpdesk
- Yes
- Self-serve sign-up
- No
Decagon builds AI agents for chat, email and voice at large consumer, fintech and telecom brands. It publishes no prices and offers no trial. Procurement data puts the median contract at $432,750 a year.
The catch: No public prices, and the pricing most often observed by buyers is per conversation, so you may pay for conversations the AI does not resolve unless you negotiate otherwise.
