Infinitus

AI voice agents that call payers so staff do not have to

Our take

Infinitus builds AI voice agents that make the phone calls healthcare staff hate: benefit verification, prior authorization status checks, and appeals follow-up with commercial and government payers and PBMs. Founded in 2019 by ex-Google engineers Ankit Jain and Shyam Rajagopalan, it sells mainly to pharma patient-access programs, specialty pharmacies, and providers, and its FastTrack product lets human callers skip IVR menus and hold queues when a live conversation is still required.

The company raised a $51.5M Series C led by Andreessen Horowitz in late 2024, bringing total funding to about $103M, with Memorial Hermann Health System joining as a strategic investor. It reports more than 100 million minutes of completed healthcare conversations and says 44% of Fortune 50 healthcare companies use it; named partners include Cencora and Fortrea Patient Access. The 2025 Salesforce partnership embeds its agents directly into Health Cloud and Life Sciences Cloud workflows, positioning Infinitus as the phone-call layer inside larger patient access stacks.

What it does

AI voice agents call payers and PBMs autonomously
Automates benefit verification for drugs and medical benefits
Checks prior authorization and appeal status by phone
FastTrack bypasses IVR menus and hold times for staff
AI guardrails constrain what agents can say and do

Where it's strong

Category pioneer in payer phone automation with over 100 million minutes of healthcare calls completed, so the model has seen most payer phone trees.
Strong compliance posture (HIPAA, SOC 2 Type 2, HITRUST-certified cloud) and published AI guardrails matter when an AI speaks to payers on your behalf.
Serves 44% of Fortune 50 healthcare companies, indicating it can pass enterprise pharma procurement.

What buyers should weigh

Roots and marquee traction are in pharma patient-access programs; provider-side RCM use is newer, so demand provider references.
It automates the phone call, not the surrounding workflow, so you still need systems to act on the data it returns.
Per-call economics only beat outsourced call centers at meaningful volume; model your call mix first.
