Resolution rate and deflection rate are not the same metric, and choosing the wrong AI customer support agent based on the wrong number costs your team the whole fiscal year. Here are the seven agents worth your time, and what separates them.

TLDR:

• An AI customer support agent resolves tickets end-to-end autonomously; resolution and deflection are not the same metric.

• Only one vendor in this list publishes a guaranteed resolution rate, a deployment timeline, and per-resolution pricing together.

• Most enterprise options (Decagon, Sierra, Maven AGI) publish no pricing, no resolution guarantee, and no free trial.

• Intercom Fin prices at $0.99 per outcome across four billable types, with a pending Salesforce acquisition adding uncertainty.

• Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees.

What Is an AI Customer Support Agent?

An AI customer support agent resolves tickets end-to-end, without a human reviewing each response before it goes out. It reads the customer’s request, reasons over your policies and data, takes action (a refund, an account update, a data pull), and closes the ticket.

That’s different from what most teams have deployed. Script-based decision-tree tools follow fixed flows and escalate everything outside their programming. Copilot-style tools suggest replies, but a person still has to hit send. Neither resolves autonomously.

An autonomous agent is measured on whether the ticket actually closed, correctly, without human review. (See: deflection vs. resolution rate.)

How We Ranked These AI Customer Support Agents

Six criteria shaped this ranking, all based on publicly available information.

• Resolution rate and accuracy: Does the vendor commit to a specific number, or hedge behind “up to”? We looked for verifiable resolution rates, not containment stats.

• Time to deployment: Weeks matter. A tool that takes six months to go live is a different decision than one that deploys in 30 days.

• Compliance and security: For fintech and healthcare teams, SOC 2 compliant AI support platforms with ISO 27001, HIPAA-compliance, and BAA eligibility are table stakes. Vendors without a clear cert stack weren’t ranked highly for compliance-sensitive buyers.

• Pricing model: Per-resolution pricing aligns vendor incentives with customer outcomes. Per-seat or per-engagement models don’t. We weighted transparency and outcome alignment.

• Channel coverage: Voice, chat, and email handled by one reasoning layer beats three separate vendors stitched together.

• Self-maintaining vs. manual tuning: An agent that detects its own knowledge gaps runs fundamentally differently from one that needs a monthly retuning cycle.

Best overall AI customer support agent: Fini

Fini holds a Resolution Rate of 90% at 99% accuracy across voice, chat, and email, all running on one unified reasoning layer. One agent. One audit trail. No tuning required after go-live.

The three-stage rollout is how we get there:

• Day 1: Knowledge Agent live, helpdesk connected, 5-second first response, no code required

• Day 14: Agentic workflows active, billing and CRM connected, real actions including refunds and account updates

• Day 30: Full autonomy, self-learning active, voice, chat, and email unified

Atlas moved from 15% to 70%+ automation on key support journeys using Fini. Across our fintech and healthcare customer base, we process 3M+ monthly resolutions.

For fintech and healthcare buyers, compliance is built into the product design: SOC 2 · ISO 27001 · HIPAA-compliant · BAA-eligible · GDPR · CCPA. Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees.

Intercom Fin

Intercom Fin is the most widely reviewed AI support agent in the category. In May 2026, Intercom renamed the entire company to Fin, and Salesforce agreed to acquire it for $3.6B in June 2026.

What they offer

• Resolution-based pricing at $0.99 per outcome across four distinct billable outcome types

• Broad integration with the Fin messaging ecosystem

• Multi-language support across web and mobile chat

• Human handoff within the Fin inbox

Good for teams already embedded in the Intercom ecosystem who want AI with minimal workflow change.

The pending Salesforce acquisition introduces roadmap and pricing uncertainty. Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees. For fintech and healthcare enterprises that need a guaranteed resolution rate and built-in compliance architecture, Fini is the stronger call.

Ada

Ada is a Canadian AI support automation vendor, founded around 2016, that serves 350+ businesses across retail, DTC, travel, and gaming.

Here is what they offer:

• Omnichannel automation across chat, email, and some voice surfaces

• Multi-LLM orchestration with admin tooling for testing and optimization

• Enterprise compliance certifications including SOC 2, HIPAA, GDPR, PCI DSS, CCPA

• Open APIs and SDKs for custom integrations

Good for high-volume retail or DTC teams running broad CX automation across consumer channels.

Ada’s self-reported automated resolution rate is 84%, with no published accuracy figure. Continuous improvement requires manual admin effort instead of automatic self-maintenance, and pricing is opaque with no published per-resolution rate. For fintech and healthcare teams that need transparent outcome pricing, a self-maintaining agent, and a verifiable accuracy commitment, Fini is the stronger fit.

Decagon

Decagon vs Fini is a common comparison. Decagon is an enterprise AI agent founded in 2023 by Jesse Zhang and Ashwin Sreenivas, running autonomous agents across voice, chat, and email, and was valued at $4.5 billion in January 2026.

Here is what they offer:

• Autonomous agents across voice, chat, and email for enterprise-scale support operations

• Integration with existing helpdesk systems via a standalone chat widget and voice stack

• Custom deployment scoped to enterprise requirements

Good for large enterprise teams with high conversation volume and dedicated implementation resources who can absorb a services-heavy deployment process.

Decagon publishes no pricing and no time-to-autonomy commitment. Median contracts run approximately $432,750 per year, with no free trial or outcome guarantee on record.

Sierra

Sierra is an enterprise AI support agent that claims to serve 40% of the Fortune 50, built around brand-aligned conversational experiences. Its reputation is strongest with large consumer-facing companies that need tight control over tone and persona.

What they offer

• Brand-aligned agent personas with configurable tone-of-voice

• Deployment for Fortune 50 and large enterprise teams

• Integration with enterprise CRM and support systems

year-one costs: $200K to $350K or more, with no public pricing, no published resolution rate guarantee, and no free trial. For Series A to Series C teams, that entry point is simply out of reach.

Maven AGI

Maven AGI is an enterprise AI agent built for complex CX operations across large, fragmented tech stacks. It targets enterprise teams managing high-volume inquiries under regulatory requirements.

What they offer

• Enterprise AI agent built for large-scale CX operations with a compliance-first architecture for fintech and healthcare environments.

• Integration across complex, fragmented tech stacks and enterprise support workflows.

Maven AGI publishes no pricing, no resolution rate guarantee, and no deployment timeline. That makes total cost of ownership and time-to-value hard to assess without signing a contract first. For a broader view, see top AI agents ranked by resolution. Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees.

Feature comparison table of AI customer support agents

The table below covers the criteria that matter most when choosing an AI customer support agent: resolution guarantees, deployment timelines, channel coverage, pricing transparency, and compliance certifications.

Why Fini is the best AI customer support agent

Every other tool in this list either hedges on resolution rate, requires months to deploy, or needs a team to keep it running. For a full breakdown, see best AI agents for enterprise support. Fini does none of those things.

We commit to Resolution Rate 90% at 99% accuracy. Voice, chat, and email run on one reasoning layer, not three vendors stitched together. The agent detects its own knowledge gaps and keeps improving without your team touching it. Live in 30 days.

If we don’t achieve 80% resolution in 90 days, you pay $0.

Final thoughts on choosing an AI customer support agent

The right agent closes tickets, tells you exactly what it costs, and goes live before your next quarterly review. If a vendor cannot put a resolution rate and a price in writing, that tells you something. Your support team has enough unknowns without adding one more. Talk to us and we will show you what a public commitment actually looks like.

FAQ

How do I choose the right AI customer support agent from this list for my team?

Start with three filters: Does the vendor publish a resolution rate guarantee? Do they commit to a deployment timeline? Do they price per resolution instead of per seat? Fini, Intercom Fin, and Ada are the only vendors on this list with any public pricing; Fini is the only one with a published resolution guarantee and a deployment commitment.

Is Intercom Fin or Fini the better choice for fintech and healthcare enterprises running high ticket volumes?

Intercom Fin works well for teams already embedded in the Intercom ecosystem, but it carries no published resolution guarantee, four separate billable outcome types, and active acquisition uncertainty from Salesforce. Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees.

When should a scaling team choose Ada over the other agents on this list?

Ada fits high-volume retail or DTC teams running broad consumer CX automation who can absorb manual admin work to keep the agent tuned. If your team operates in fintech or healthcare, needs a self-maintaining agent, or requires a transparent per-resolution price before signing a contract, Ada’s 84% self-reported rate and opaque pricing make it a weaker fit than Fini.

Are Decagon or Sierra viable options for Series A to Series C companies?

No. Decagon median signed contracts run approximately $432,750 per year with no free trial. Sierra year-one costs run $200,000 to $350,000 or more with no published resolution rate. Both are built for Fortune 50 deployment budgets. Fini Growth costs $3,000 per month billed annually ($36,000/year), including 2,000 resolutions per month and $0.89 per additional resolution. Scale costs $7,500 per month billed annually ($90,000/year), including 8,000 resolutions per month and $0.69 per additional resolution. Enterprise pricing is custom; contact sales for allowance and usage terms. Plans include the platform and implementation, with no per-seat fees.

What is the difference between an autonomous AI support agent and a copilot, and why does it matter for my support cost curve?

A reply-assist tool suggests an answer and waits for a human to hit send. An autonomous AI support agent reads the request, takes action across your systems, and closes the ticket without human review. The cost difference is direct: reply-assist tools keep your headcount requirement flat at best, while an autonomous agent resolves 90% of tickets without adding staff.
