Estimates assume 5,000 conversations a month, 60% handled by AI and 10 agent seats, at each vendor's published list price (the cost calculator's model); treat them as a floor, not a quote. Compliance rows are what vendors publicly claim, and “Not verified” means we have not confirmed that fact yet, not that the tool lacks it.
Choose Intercom or Sierra AI?
Choose Intercom if
Best for: SaaS, fintech and ecommerce support teams that want an AI-first helpdesk with Copilot in the inbox and the Fin agent built in, starting at $19 per seat a month billed annually plus $0.99 per Fin outcome, with US, EU or Australian hosting and SOC 2, HIPAA and ISO 42001 coverage.
- you need agent-assist copilots for human reps
- you need a full help desk and ticketing suite
- you need Social coverage
- you prefer a flat subscription to usage-based billing
Look elsewhere if you want a flat, predictable bill or an independent vendor: seats, Fin outcomes, Copilot and channel usage are metered separately, and the company is now owned by Salesforce.
Choose Sierra AI if
Best for: Large brands that want one branded agent deployed across chat, voice, email, SMS and WhatsApp, with voice agents that can take a payment mid-call, outcome-based pricing, 59 languages and the broadest compliance list in the directory including FedRAMP, ISO 42001 and the EU AI Act.
- you need enterprise scale, security, and compliance
- you need voice and phone AI
- you need a vendor that publicly claims PCI DSS, FedRAMP, and EU AI Act
- you would rather pay per resolved ticket than per seat
Look elsewhere if you are not an enterprise: Sierra sells multi-year contracts by quote with no trial or self-serve start, and its verified facts do not include a stated data residency.
About Intercom
Intercom is the customer service suite that the Fin AI agent was built on: an omnichannel inbox, a ticketing system, a help center, outbound messaging, reporting and a Knowledge Hub that feeds both the AI and the human team. This listing covers that helpdesk. Fin, Intercom's AI agent, has its own listing in this directory, because it is also sold on its own for teams that keep Zendesk, Salesforce, HubSpot or Freshdesk underneath. The AI piece that belongs to the helpdesk itself is Copilot, an assistant in the inbox that reads the whole thread, internal notes and customer data before a teammate opens the conversation, drafts a reply from the knowledge base and past conversations, and pulls context from GitHub, Linear and Notion. It can update a ticket or log an issue in those tools with the teammate's approval, and it stops to ask if a reply looks like it has the wrong customer details or belongs to another conversation.
The design choice worth understanding is that Fin and the human team share one record, one inbox and one knowledge base. When Fin needs an approval it asks a teammate and then finishes the conversation itself, and managers get suggestions on missing content or data integrations to fix. Tickets come in three shapes: customer issues, back-office collaboration and tracker tickets that tie many reports of one widespread problem together. The inbox handles chat, email and phone as core channels, plus WhatsApp, Instagram, Facebook, Discord, SMS and shared Slack channels, and the help center publishes in 45 languages across multiple brands.
Eoghan McCabe, Des Traynor, Ciaran Lee and David Barrett founded Intercom in 2011. In 2026 the company renamed itself Fin after its AI agent, and Salesforce completed its acquisition of Fin, formerly Intercom, on September 10, 2026, with Fin placed inside Salesforce AI Labs; intercom.com still sells the helpdesk under the Intercom name. It reports more than 30,000 customers. Neo Financial credits it with replacing a stitched-together stack with one system for AI and human support, and Anthropic reports around 560,000 Fin resolutions a month at about a 79 percent resolution rate. Intercom holds SOC 2 Type II, HIPAA, ISO 27001, ISO 27701 and ISO 42001, with hosting in the US, EU or Australia.
Pricing has two parts: seats and usage. On annual billing the Essential plan is $19 per seat a month ($29 month to month), Advanced $85 and Expert $132, and every plan includes Fin at $0.99 per outcome. Copilot is an add-on at $29 per agent a month billed annually, after 10 free Copilot conversations per agent each month, and WhatsApp, SMS, phone and email campaigns are pay-as-you-go. There is a 14-day free trial with no card. Choose Intercom if you want the helpdesk and the AI agent as one system rather than two vendors stitched together, especially for SaaS, fintech or ecommerce support. Skip it if you want a flat, predictable bill or a vendor outside Salesforce: seats, outcomes, add-ons and channel usage all meter separately.

About Sierra AI
Sierra builds conversational AI agents for the enterprise, and it arrived with about as much star power as a startup can carry. It was founded in 2023 by Bret Taylor and Clay Bavor, and if those names ring a bell it is because Taylor co-created Google Maps, served as CTO of Facebook and co-CEO of Salesforce, and currently chairs the board of OpenAI, while Bavor spent eighteen years at Google leading its virtual and augmented reality work. Company lore says the whole thing was hatched over a grilled branzino lunch in Palo Alto.
The product lives up to the pedigree. From a single build, Sierra deploys a branded agent across chat, voice, email, SMS, and even ChatGPT, following your policies, adopting your brand's voice, and escalating gracefully when a conversation gets thorny. Its voice agents are a standout: they hold natural, low-latency conversations, read sentiment, and can even take a credit card or ACH payment over the phone in one uninterrupted call, with no clumsy handoff to a separate system.
Under the hood sits Agent OS, a platform for building, testing, and supervising agents, with tooling to run voice simulations and rehearse behavior before anything reaches a real customer. Pricing is outcome-based, tied to conversations or successful resolutions and wrapped in multi-year enterprise contracts, so Sierra is aimed at large brands rather than weekend experimenters. Reported customers include SoFi, Ramp, and Brex, and the company says its agents already serve a meaningful slice of the Fortune 50.
Sierra's fundraising has kept pace with its towering ambition, vaulting the company into the rarefied tier of the most valuable AI startups in barely two years. For enterprises that want polished, on-brand agents across every channel and are willing to invest the time and budget to do it properly, Sierra is a genuine marquee choice.
