Fini ships a finished agent. Retell AI ships you the infrastructure to build one.
Retell AI and Fini both come up in searches for AI voice agents, but they are not solving the same problem. Fini is a finished, per-resolution AI agent built specifically for fintech and healthcare support, live in 30 days with native integrations into claims, billing, and EHR systems. Retell AI is voice AI agent infrastructure, APIs, SDKs, and a no-code studio that a technical or ops team uses to build, configure, and own its own voice agent, with pricing metered by the minute.
This comparison is honest about that mismatch. Retell AI is a genuinely capable platform for teams who want to build their own voice agent and are comfortable choosing an LLM, a voice, and a telephony stack themselves. Fini is built for regulated fintech and healthcare teams who need a working, compliance-aware resolution agent on day one, not a developer kit to assemble one.

What is Fini?
Fini is an AI customer-support agent priced per resolution, backed by Y Combinator and Matrix Partners. It connects natively to helpdesk, knowledge base, CRM, billing, claims, and EHR systems, so it can take real action on tickets rather than just answering questions from a script.
Fini resolves 90% of support volume at 99% accuracy, goes live within 30 days, and already handles more than 3 million monthly resolutions for fintech and healthcare companies. It works across voice, chat, and email, supports 130+ languages, and responds to a new conversation in about 5 seconds.
Fini charges a starting rate of $0.49 per resolution, with no per-seat fees, so cost scales with outcomes rather than headcount or conversation volume. Its pricing also includes the 90-Day Money-Back Guarantee: if Fini does not reach a 90% resolution rate within 90 days of going live, you are not charged for the shortfall.
What is Retell AI?
Retell AI is a San Francisco voice AI agent platform founded in 2023, backed by Y Combinator (Winter 2024 batch), with a team of roughly 50 people per YC's own listing. A specific funding amount beyond its YC backing is not publicly confirmed, so this comparison does not state one.
The product is voice agent infrastructure: real-time speech recognition, a proprietary turn-taking model, function calling into external systems like CRMs and calendars, and multi-channel support across voice, chat, SMS, and API. Retell markets roughly 600ms end-to-end latency and sells to both technical teams building through its APIs and SDKs and non-technical operators using its drag-and-drop studio builder. The details are on Retell AI's own site.
That positioning matters for this comparison. Retell explicitly sells the ability to build and own your voice agent rather than depend on a vendor for every change. That is a legitimate, different buying motion from Fini's finished, compliance-hardened resolution agent, but it also means the agent's logic, knowledge, and guardrails are yours to design and maintain.
Retell AI pricing in 2026
Retell AI prices by consumption, not by resolution or seat, and its pricing is published and self-serve rather than custom-quote-only. New accounts get $10 in free credit and 20 free concurrent calls with full platform access from day one.
Voice agents run $0.07 to $0.31 per minute depending on which LLM and voice you choose, broken down roughly as $0.055/min for Retell's voice infrastructure, $0.015/min for text-to-speech, $0.003 to $0.16/min for the LLM depending on model tier, and $0.015/min for US telephony. Chat agents are billed at $0.002 or more per message. Add-ons include a knowledge base at $0.005/min or $8/month, advanced denoising at $0.005/min, PII removal at $0.01/min, and extra concurrent call slots at $8/month each beyond the free 20. Only connected call time is billed, though silence and hold time counts. Custom pricing is available and adds a dedicated server and 24/7 support.
The contrast with Fini is structural. Retell's per-minute, per-model pricing means the buyer chooses the LLM, voice, and add-on stack, and the bill varies with conversation length regardless of whether the issue was resolved. Fini's $0.49 per resolution is an outcome price with a resolution guarantee built in, so cost tracks results rather than minutes talked.
How Fini and Retell AI differ
The core difference is finished vertical agent versus general-purpose voice infrastructure. Fini is purpose-built for fintech and healthcare support: the integrations, resolution logic, and compliance posture are already built for those use cases, and you go live in 30 days. Retell AI is a horizontal platform that can be pointed at almost any voice use case, including lending or insurance calls, but the agent's knowledge, escalation rules, and system connections are yours to build with its agentic AI building blocks.
That shows up in Retell's own case studies. It has real fintech and healthcare-adjacent customers, Pine Park Health for senior care call automation, Medical Data Systems for medical debt collections calls, Sunshine Loans for loan application intake, and Matic Insurance for insurance call workflows, but these are front-of-house call volume use cases: intake, qualification, and collections calls. None of them describe integration with a core banking system, a claims-processing system, or an EHR, the system-of-record depth Fini builds in natively.
Capabilities side by side
At a functional level, the two products serve different buyers. The table below lines up the core capabilities most teams evaluate first.
Capability | Fini | Retell AI |
|---|---|---|
Primary focus | Finished AI agent for fintech and healthcare support | Voice AI agent infrastructure for developers and no-code builders |
Time to go live | 30 days | Minutes for a basic voice agent; longer for custom function calls and regulated workflows |
Pricing model | $0.49 per resolution, no per-seat fees | Usage-based, $0.07 to $0.31 per minute plus add-ons, Enterprise custom |
Vertical integrations | Native to claims, billing, CRM, EHR, helpdesk, knowledge base | Native CRM and telephony connectors; no native core-banking, claims, or EHR connectors |
Resolution guarantee | 90-Day Money-Back Guarantee: 90% in 90 days or no charge for the shortfall | No resolution-based guarantee; cost is tied to minutes used, not outcomes |
Feature by feature
Zooming into individual features shows the same pattern: Fini ships a tuned outcome, Retell AI ships the raw components to build toward one.
Feature | Fini | Retell AI |
|---|---|---|
Channels | Voice, chat, email | Voice, chat, SMS, API |
Languages | 130+ | Not specified as a fixed number on public pricing or product pages |
Resolution accuracy | 90% resolution at 99% accuracy | Not published as a resolution or accuracy metric; case studies cite call-volume and cost outcomes instead |
Latency | First response in about 5 seconds | Roughly 600ms end-to-end voice latency claimed on-site, not independently benchmarked |
Knowledge grounding | Built in, tuned for regulated support content | Knowledge base add-on you upload and connect yourself |
Multi-step workflows and tool calls | Native to the agent | Available via function calling you configure per agent |
Escalation to a human | Built into the core workflow | Configurable transfer and IVR routing you set up |
Vertical connectors (claims, EHR, core banking) | Native | None found for core banking or claims; EHR (including Epic) requires a custom-built function |
Ease of use and admin experience
Fini's onboarding is closer to an implementation project than a build project: connect your existing systems, and Fini goes live in 30 days on top of your own data. There is no agent-building canvas because the agent, its integrations, and its escalation logic are already built for fintech and healthcare support.
Retell AI's admin experience genuinely spans both audiences it targets. Its studio builder lets non-technical operators assemble a voice agent without code, and its APIs and SDKs give technical teams full control over prompts, function calls, and voice selection. Its integrations catalog has real native connectors for CRM (HubSpot, Salesforce, Zoho CRM, Go High Level, Microsoft Dynamics 365), telephony (Twilio, Vonage, Telnyx, Five9), and calendars (Calendly, Cal.com). But that native depth stops at generalist categories: healthcare EHR systems, including Epic, require the customer to build a custom function against their own API layer, and no core-banking or claims-processing connector is listed at all, native or otherwise. Anything outside the native list falls back to Zapier, Make, or n8n-style automation.
Fini's differentiators
Built for regulated industries, not configured for them
Fini's integrations into claims, billing, CRM, and EHR systems are native, not something you build a custom function to reach. Retell AI's own documentation is explicit that EHR access, Epic included, is customer-built, and no core-banking or claims connector exists in its catalog at all.
Resolution-based pricing, not consumption-based
At $0.49 per resolution with no per-seat fees, Fini's cost tracks outcomes. Retell AI's $0.07 to $0.31 per minute pricing means the bill depends on call length and which LLM and voice you picked, whether or not the call actually resolved the customer's issue.
A guarantee, not a variable bill
Fini's 90-Day Money-Back Guarantee means that if it does not hit 90% resolution within 90 days of going live, you do not pay for the shortfall. Retell AI has no analogous resolution guarantee; cost scales with minutes used regardless of outcome.
A finished vertical agent, not a horizontal platform you specialize
Fini goes live in 30 days already tuned for fintech and healthcare support. Retell AI's real fintech and healthcare-adjacent customers, lending intake, insurance workflows, senior care, medical collections, are front-of-house call automation, not regulated back-office or system-of-record integration.
Retell AI's recognized strengths
None of this makes Retell AI a weak product, it makes it a different one. Retell AI backs its HIPAA, SOC 2, and GDPR claims with a real Vanta-hosted trust center and self-serve BAA and DPA agreements available at no extra fee, a genuine sign of healthcare-readiness that goes beyond a marketing badge. Its published, self-serve per-minute pricing (no custom quote required to get started) is more transparent than many voice AI vendors. It has a strong developer experience: real APIs and SDKs alongside a no-code studio, native SIP telephony for major carriers, and a Y Combinator (Winter 2024) pedigree that speaks to product execution speed. It also has genuine, named fintech and healthcare-adjacent case studies, including a lender processing 700,000-plus monthly applications and a healthcare collections company scaling to $280,000 in monthly collections.
One caveat worth flagging: Retell AI's homepage claims ISO 27001 compliance alongside HIPAA, SOC 2, and GDPR, but its own compliance documentation page lists only HIPAA, SOC 2, and GDPR, with no mention of ISO 27001. That is a discrepancy between the homepage and the compliance docs, not a confirmed certification, and it is worth verifying directly with Retell AI before relying on it.
For a technical or ops team that wants to design its own voice agent, choose its own LLM and voice per use case, and is comfortable with usage-based billing, Retell AI is a well-built platform to do that on.
What customers say
Fini customers describe measurable resolution outcomes on live support volume, not just a smoother agent-building experience.
Retell AI's own case studies tell a call-volume and cost story rather than a resolution-rate story: Sunshine Loans cites scaling to more than 700,000 monthly loan applications while cutting abandonment to 5%, Medical Data Systems cites scaling to $280,000 in monthly collections, and Pine Park Health describes automating senior-care call intake. G2 and Capterra review pages for Retell AI were not reachable during this research pass, so this comparison does not cite a star rating or review count for Retell AI; verify current review data directly before relying on it.

Which should you choose?
Choose Retell AI if you have engineering or ops time to build and own a voice agent, want to pick your own LLM and voice per use case, and your support volume is front-of-house call handling, intake, qualification, or collections calls, rather than deep integration with a regulated system of record.
Choose Fini if you are a fintech or healthcare company that needs an agent live in 30 days, resolving real tickets against your claims, billing, EHR, or core systems, without spending engineering time building and maintaining voice agent logic yourself. If you are evaluating other voice AI platforms too, see how Fini compares to Vapi and ElevenLabs.
Compliance
Retell AI's compliance posture is more substantive than a typical developer-tool marketing page. It backs HIPAA, SOC 2 Type I and II, and GDPR claims with a real Vanta-hosted trust center and offers self-serve BAA, DPA, and Standard Contractual Clauses at no extra fee, a genuine readiness signal for regulated customers. The one discrepancy worth flagging: its homepage claims ISO 27001 compliance, but the dedicated compliance documentation page does not list ISO 27001 at all. Treat that claim as unconfirmed until Retell AI clarifies it directly.
Fini serves fintech and healthcare customers handling regulated data through native integrations into claims, billing, and EHR systems, and publishes its own security posture at usefini.com/security. If compliance certifications are a hard requirement for your deployment, confirm the current status directly with both vendors rather than assuming parity.

Is Retell AI a good fit for fintech or healthcare support?
Retell AI has real fintech and healthcare-adjacent case studies, including lending intake, insurance workflows, senior care, and medical collections calls, so it is not a bad fit outright. But these are front-of-house call automation use cases. Retell AI has no native core-banking or claims-processing connectors, and EHR integration, including Epic, requires a customer-built custom function, so it lacks the system-of-record integration depth Fini builds in natively for regulated support.
What does Retell AI cost in 2026?
Retell AI prices by usage. Voice agents run $0.07 to $0.31 per minute depending on the LLM and voice chosen, chat agents run $0.002 or more per message, and add-ons like a knowledge base, denoising, or PII removal cost extra. New accounts get $10 in free credit and 20 free concurrent calls. Custom pricing is available.
How is Fini's pricing different from Retell AI's?
Fini charges a starting rate of $0.49 per resolution with no per-seat fees, so cost scales with outcomes. Retell AI charges per minute of usage, so the bill depends on call length and which LLM and voice you selected, regardless of whether the call actually resolved the customer's issue.
Is Retell AI a finished agent or developer infrastructure?
It is fundamentally developer and no-code infrastructure for building voice agents. Retell AI provides APIs, SDKs, and a drag-and-drop studio, plus real native connectors for CRM and telephony, but you still design the agent's prompts, function calls, and escalation logic yourself.
Is Retell AI HIPAA and SOC 2 compliant?
Retell AI claims HIPAA, SOC 2 Type I and II, and GDPR compliance, backed by a real Vanta-hosted trust center and self-serve BAA and DPA agreements. However, its homepage also claims ISO 27001 compliance, and that certification is not listed on its own compliance documentation page, a discrepancy worth confirming directly before relying on it.
How fast can I go live with Fini versus Retell AI?
Fini goes live in 30 days on your own data, with claims, billing, CRM, and EHR integrations already built in. Retell AI can get a basic voice agent running in minutes through its studio, but a multi-step, compliance-aware agent with custom function calls for regulated workflows takes real configuration and development time.
