Sierra AI pricing in 2026: the platform fee, the rate per resolution and setup

Sierra says it is paid only when its agent completes a task, but its own AWS listing also sells platform access by private offer, and no one outside a contract knows what either costs. We found no pricing page, free trial or self-serve sign-up, so a sales call is the only way in.

The amounts in circulation come from other companies, and every dollar figure on this page is in US dollars. Blogs from Fin¹ and CloudTalk put the platform fee at about $150,000 a year, and CloudTalk and BuildMVPFast price a resolution at $1.00–$2.50. None of them names a contract or a buyer. Spread over twelve months, that fee alone is $12,500 a month before the first resolution.

How Sierra bills

Sierra says it charges for results. Elliot Greenwald wrote in December 2024 that “With outcome-based pricing, Sierra gets paid only when we complete a task for you.”² The post lists what can count as an outcome: “a resolved support conversation, a saved cancellation, an upsell, a cross-sell, or any number of valuable outcomes.” Sierra’s word is outcome. We say resolution for the one a support team pays for, a resolved conversation.

A conversation the AI does not resolve usually costs nothing. The post puts it as “If the conversation is unresolved, in most cases, there’s no charge.” What counts as a resolution is not published. Sierra promises “clear, agreed-upon criteria for each outcome upfront”, so the definition lives in your contract.

Some flows are billed another way. The post says Sierra will “create a blended pricing approach”, and that “routing or greeter-style interactions may align better with consumption-based pricing, where payment is based on conversation count, regardless of the outcome.” A June 2026 post called “Outcomemaxxing” holds the same position: “Pricing by outcome is nuanced, so we’re not dogmatic about it and do consumption-style work where it fits the shape of the problem.”³

The AWS Marketplace listing adds a platform access fee to that picture. Sierra wrote the listing as the seller,⁴ and it has two dimensions: “Sierra Platform”, where “pricing is determined via private offer”, and “Sierra Outcomes”, counted per unit. Each shows a placeholder amount on the page, and the listing says both dimensions “are quoted rather than fixed, so you agree on quantities and pricing with the vendor directly”, so we quote neither. A fee for access is owed before any task is done, which sits awkwardly beside “only when we complete a task”. We take the listing as the better guide to the invoice, because it is the page written to be bought from, and its own highlight line still reads “Long-term partnership, priced by outcomes.”

The pricing page on sierra.ai returns a 404, and the site-wide terms, effective 12 February 2024, hold no fee clauses.⁵

The figures in circulation

The first two rows are Sierra’s own statements; the other four are estimates from other companies’ pages.

Vendr, the usual place to find purchase data, has little on Sierra: its page shows no price, and the data behind the page holds a single purchase record that Vendr itself does not rate.⁸ That leaves estimates only.

Where the platform fee and rate come from

By one guide’s account, the platform fee began with Fin. Macha’s guide, published 23 September 2026 and updated 6 October 2026, says “The only public dollar estimate, $150,000 or more a year, comes from its competitor Fin.”⁹ Macha is a rival vendor as well, and it is the only page we found that says this.

Fin’s guide gives the fee, a setup range and a year-one total, and credits them to “third-party estimates from procurement data platforms and independent analyses”. It links none, so we cannot check them. CloudTalk’s guide, updated 3 July 2026, gives the same fee and the same setup range, adds “and up” after the fee, and says Sierra has “never confirmed publicly”.⁶ It names no origin either. That a platform fee exists is published; its amount rests on one competitor’s page and a second page that repeats it.

The rate is no better sourced. CloudTalk writes “$1–$2.50 per successful outcome”. BuildMVPFast, on 17 August 2026, writes that “Third-party contract analyses put the going rate at roughly $1.50 per resolved conversation, in a band of about $1.00 to $2.50 depending on volume, channel, and complexity.”⁷ No analysis is named. We searched TechCrunch, Sacra, Salesforce Ben and Sierra’s own posts for one and found none; Sacra describes the model and gives no rate. Two pages with the same band amount to one claim, since neither shows where it came from.

The calculator uses the band, $1.00–$2.50, and leaves out BuildMVPFast’s single figure of about $1.50 a resolution. Picking one point in a band nobody sourced would claim more than we know, and the band at least shows how wide the doubt is.

Costs the figures leave out

Setup is a one-time cost with an estimate of its own. Fin and CloudTalk put it at $50,000–$200,000. Sierra’s AWS listing invites buyers to “Work with an expert agent development team that has supported hundreds of deployments” and does not say what that costs. The platform fee plus setup comes to $200,000–$350,000 or more in year one, which is the total in Fin’s guide.

Integration work falls on your side as well. One reviewer on Gartner Peer Insights, an audit manager in energy and utilities, wrote about connecting Sierra to ServiceNow.¹⁰

“Deploying Sierra to our ServiceNow instance was a greater challenge as it seemed to be heavy lifting. It required custom level API work to bridge into our systems. It takes anywhere from 8 to 16 weeks.”

The reviewer is one person. Sierra’s case studies for melin,¹¹ Vivid Seats,¹² Airtable,¹³ Next¹⁴ and Singtel¹⁵ run from under two weeks to under ten weeks, and the 8–16 weeks the reviewer gives reaches well past the longest of them. Those are customers Sierra chose to feature.

Sierra’s AWS listing says its fees cannot be cancelled or refunded, except where the law requires it. We could not read Sierra’s customer contracts, so renewal terms, minimums and any escalation clause are unchecked.

Resolution charges grow as the agent improves, because every extra resolution is billable. At 3,000 conversations a month, moving from 60% resolved to 85% adds $750–$1,875 a month. That follows from the model, and no buyer we found has complained of it.

On the first call, ask Sierra for the platform fee and for anything charged ahead of it, the contract’s definition of a resolution, the flows billed per conversation and their rate, the cost of setup, and the renewal terms.

What 3,000 conversations a month costs

Sierra’s side of the calculator is the fee spread over twelve months plus every resolution at the rate, so it moves with the share the AI resolves and not with conversations alone. The per-conversation flows are left out because no rate exists for them, and so is setup, which is paid once.

At the default, the fee sets the bill. 3,000 conversations with 60% resolved is 1,800 resolutions, and the fee is about $150,000 a year, or $12,500 a month. On the low side, 1,800 resolutions at $1.00 add $1,800, so the month is $14,300. On the high side, at $2.50 they add $4,500, so it is $17,000. The fee is 87% of the low bill and 74% of the high one, and counting the fee each resolution costs $7.94–$9.44.

Resolution charges pass the fee at 12,500 resolutions a month on the low side ($12,500 divided by $1.00) and at 5,000 on the high side ($12,500 divided by $2.50). At 60% resolved, those are about 20,800 and 8,300 conversations a month. At 30,000 conversations the month is $30,500–$57,500: 18,000 resolutions add $18,000 or $45,000 to the fee, and each resolution costs $1.69–$3.19 all in.

The calculator counts the fee at the same amount on both sides. The sources add “and up” to it, so the high figures here are not ceilings. Over a first year at the defaults, resolution charges come to $21,600–$54,000, which puts the fee, setup and resolutions together at $221,600–$404,000.

Who it’s right for

The strongest case for Sierra is a large brand that wants someone else to build and run its agent. TechCrunch reported in September 2025 that Sierra “claims to have landed hundreds of customers, including SoFi, Ramp, and Brex”,¹⁶ and in November 2025 Sierra announced $100 million in annual recurring revenue seven quarters after launch.¹⁷ On the outcome part of the bill the risk of the AI failing sits with Sierra, since an unresolved conversation usually costs nothing. The fee has no such protection.

The one detailed buyer review we could read is positive about reach. The Gartner reviewer says Sierra “treats every communication channel as an entry point into the same underlying system”, so a customer can start in a mobile app and carry on over SMS or a phone call, and that “it handles complex backend tasks on the database rather than just reviewing FAQ answers.” Gartner Peer Insights reviewers rate Sierra 4.7 across 7 ratings, a small base. The same reviewer’s headline holds both sides: “Deep API integrations enhance flexibility, though initial integration is complex but powerful.”

G2 carries more Sierra reviews than Gartner does, but it blocked every fetch we made, so we have read none of them and quote none.

Where Ezro is different

Sierra’s bill starts with a platform fee and setup that nobody outside a contract has seen. Ezro starts at $99 a month. The plans are priced on the pricing page, so you can read the first bill before you speak to anyone. Ezro is an AI operator: you write the steps your team follows for a job, such as a refund or a delivery check, and it works through them in your helpdesk and order systems. On Starter and Growth, a resolution past the plan’s allowance costs $0.40 to $0.50. A resolution counts only once the customer has stayed quiet for 72 business hours, and handoffs to your team are never counted either way.
