Infinitus alternatives for payer calls and claim follow-up

What is Infinitus?

Infinitus Systems is a San Francisco company, founded in 2019, that sells healthcare voice AI. Its AI agents call payors, patients and providers. With payors, they handle benefit verification, prior auth status, formulary exception status and appeals status. They also cover bridge-program reverification and insurance discovery. Infinitus says it collects data from clearinghouses and payors digitally before it places a call. It also runs an electronic benefit verification step for Medicare Part B and commercial payers.

FastTrack is its copilot. It navigates payor phone trees and hold time, then hands the live call to a staff member. Infinitus says it can "navigate over 1,000 payor IVRs" and lists claim status follow-ups among the tasks. Studio is a no-code agent builder with connectors to CRMs, payor portals, Salesforce and Veeva.

The company is large and well funded. It raised a $51.5 million Series C led by Andreessen Horowitz in October 2024. It reports over 100 million minutes of calls and says it is used by 8 of the top 10 pharma manufacturers.

Who Infinitus is built for (and who it is not)

Infinitus calls itself "the expert in speciality medication benefit verifications". It says its agents can collect 150 data points per call. The quotes on its site come from pharma patient access teams, a national specialty pharmacy, a Medicare Advantage plan and hub operators. Rx Almanac's buyer guide puts it in the pharma hub lane: "Infinitus and Neon Health are the direct hub-automation screen".

Claim status does appear, but as one line. The payors page mentions agents and copilots that help with "claim status, appeals, and over-the-phone submissions." The providers page is mostly about calls to providers, such as confirming directory details. We found no mention of dental payers on any Infinitus page we read.

Specialty drug benefit verification at volume is Infinitus's home ground. Following unpaid claims, balancing remits and tracking enrollments across many practices is a different job.

How we compared

• Who it is for: pharma and specialty pharmacy, health plans, billing companies, EHR vendors or dental teams.
• What work it covers: benefit verification, prior auth, claim status, remits, ERA/EFT enrollment, underpayments and appeals.
• How it connects: EDI, portal automation or phone calls, and whether results land back in the CRM, PM system or EHR.
• Pricing model: only what each vendor or a named third party publishes. Where nothing is public, we say so.
• Who decides: what the software does on its own and what stays with your team.

We read each vendor's public pages on October 24, 2026. Infinitus's site blocks automated readers, so we read its pages through Wayback Machine captures from May to October 2026, linked in each fact.

Infinitus competitors, compared

The alternatives, one by one

Infinitus

Infinitus says you can "submit benefit verifications in bulk via our portal or automatically by API". It states it is "HIPAA and SOC 2 Type 2 compliant" and runs on a HITRUST certified cloud. Its pricing page describes "annual platform and license fees combined with usage (i.e. per task or minute) as well as a subscription model." Multi-year contracts with monthly minimums get discounted rates.

Best for: pharma manufacturers, hubs and specialty pharmacies running benefit verification and prior auth calls at scale.

Where it beats Daybook: for any pharma or specialty pharmacy workflow, Infinitus is the only one of the two that does the work. It states SOC 2 Type 2 compliance today, while Daybook's SOC 2 audit is in progress. It also publishes far more customer proof.

Other hub-automation vendors

If you are a pharma hub and want a like-for-like rival, Rx Almanac pairs Infinitus with Neon Health. We did not review hub vendors here because they sit outside billing work. Rx Almanac's vendor profile tells buyers to "Confirm payer acceptance, blocked-call handling, human escalation paths."

SuperDial

SuperDial builds voice agents for payer operations and names RCM companies first among its customers. Its claim status agent returns paid amount, allowed amount, patient responsibility, payment date and check or EFT number. It checks EDI, APIs and payer portals first and calls only for what is still missing. A human ops team steps in when the AI cannot finish a call. Customers pay per completed call.

Best for: billing firms and DSOs whose main pain is hold time and payer calls, medical or dental.

Where it beats Daybook: SuperDial already holds SOC 2 Type II and HITRUST e1, publishes more case studies and offers patient calling. For the two head to head, see SuperDial vs Infinitus. For more options, see SuperDial alternatives.

Daybook

Daybook Health is infrastructure for healthcare billing: agents for claim status, remits, ERA enrollment and underpayment detection, run for the medical billing companies, EHR and practice management vendors and dental billing teams that own the practice relationship.

Every unpaid claim gets a 276 overnight, without a portal login. The 277 answer lands on the claim in plain words, with the denial reason and the next step. Every 835 is proven to the cent and matched to its claims line by line. ERA and EFT enrollment is checked payer by payer for every provider you bill for. Each paid line is re-adjudicated against the payer contract. A short payment is flagged with the contract line it missed, and an appeal is drafted.

Daybook also calls the payer, waits on hold, works the phone tree and puts the reference number and the answer on the claim. Like Infinitus, it offers two modes. A dialer waits on hold and hands the live call to your biller, or a voice agent handles the whole call using the scripts in your knowledge base.

Nobody switches software. Your billers make every call on appeals, write-offs and posting, and the rules are written as fixed code, not left to an AI model. Pricing is usage based, with no subscriptions and no seats. It starts on one practice.

Best for: medical billing companies, EHR vendors and dental billing teams that want claim follow-up done inside the systems they already run.

Where it falls short: Daybook does not do pharma or specialty pharmacy work, and does not sell to individual practices.

An offshore AR team

Offshore staff log into your PM system and payer portals. One Philippines staffing firm quotes $10 to $14 an hour for an A/R follow-up or denial specialist. The trade-offs are in Daybook vs offshore AR follow-up teams.

Best for: teams that want people on the phones and are comfortable with offshore data handling.

Which Infinitus alternative fits you?

• You verify specialty drug benefits for patients starting therapy. Stay with Infinitus or compare it with other hub vendors. Daybook does not do this work.
• You are a billing company and payer calls are the bottleneck. Compare SuperDial and Daybook, and ask each what it checks before it picks up the phone. SuperDial checks EDI, APIs and portals first. Daybook sends a 276 for every unpaid claim overnight. See how to check claim status without portal logins.
• You need claims followed all the way to payment. That means status, remits, enrollment and short payments together. See claim status automation for billing companies.
• You bill for dental offices. We found no mention of dental payers on Infinitus's site. See Foji alternatives.
