Agentic AI that argues with insurance companies so billing teams don't have to.

There is a job in American healthcare that nobody grew up dreaming about: calling an insurance company to ask why a claim was denied, sitting on hold, and doing it again tomorrow. Amperos Health built an AI to do that job.
Amperos Health is a New York-based technology company that automates insurance denial management and revenue recovery for medical providers. Its product - an AI biller named Amanda - works inside the billing software providers already use, following up on claims, placing calls to payors, filing appeals, and collecting on money that has already been earned but not yet paid.
The problem it targets is enormous and unglamorous. By the company's accounting, U.S. providers lose roughly $262 billion a year to denied insurance claims, and spend another $26 billion just trying to recover it. Around 63% of revenue cycle management teams are understaffed, and turnover in billing roles runs near a third every year.
Amperos's answer is to let AI hold the line for the repetitive work - the tenth follow-up, the copy-paste appeal, the claim too small for a human to bother with - while people handle the cases that need judgment. As co-founder and CEO Michal Miernowski puts it, the pitch is blunt: software that doesn't burn out.
Founded in 2023, the company reached more than 3,000 clinical locations across all 50 states within about three years, and now supports roughly $700 million in recovered revenue annually across more than 500,000 claims. In April 2026 it raised a $16 million Series A led by Bessemer Venture Partners.
AI doesn't get tired, doesn't quit, and doesn't need to be retrained.
The case for Amperos starts with the size of the gap between care delivered and care paid for. The chart below reflects figures the company cites for the U.S. denial economy.
Amperos gave its AI a human name and a human job. Amanda is a multi-modal agent that navigates insurance portals and phone systems to reverse denials and collect outstanding claims - trained, the company says, by experienced healthcare billers.
An agentic AI that works across payor portals and phone lines, figures out how to reverse a denial, and executes chains of actions with no configuration required.
End-to-end automation of the full workflow - first-touch payor tasks, resubmissions, portal follow-ups, appeals and calls - inside providers' existing billing software.
Analytics that surface payor patterns and denial root causes, plus structured workqueues that prioritize the highest-impact claims and unify financial data.
Amanda has allowed our team to spend more time on the most valuable work, and less time doing the mundane tasks.
Traditional revenue cycle vendors, offshore billing firms and point-solution software tend to automate a single slice of the process. Amperos positions itself as AI-native and end-to-end: one system that carries a claim from denial to payment rather than handing it off between tools and teams.
A telling detail is what Amanda does with small claims. Human billers often write off low-dollar denials as not worth the time. An AI that never tires has no such threshold - so Amperos chases the claims that others quietly abandon. Small money, at 500,000 claims a year, adds up.
The company reports 22% more recovered per claim at up to 50% lower cost to collect, and 60%+ reductions in accounts-receivable backlog for customers.
We've recovered 24% more claims without increasing headcount.
Amperos sells to healthcare providers and their revenue cycle teams - multi-specialty groups, physician practices and telehealth platforms - on a subscription and volume-based model that plugs into the billing systems they already run. Named customers span specialties from dermatology to anesthesiology to substance-use telehealth.
Michal Miernowski, Alvin Wu and Wilson Wang start Amperos to attack denial management with AI.
The AI biller debuts in June 2025, backed by strategic VCs and angels from OpenAI, Twilio and Stripe.
Closed in April 2026 with Uncork Capital and Neo. Total funding reaches ~$20.2M. The round reportedly went from pitch to term sheet in about ten days.
Amperos is the first truly agentic AI platform to automate denial workflows end-to-end, from portal follow-ups to appeals.
The AI biller has a first name - Amanda - and has already made more than 75,000 calls to insurance companies.
The Series A reportedly went from first pitch to signed term sheet in roughly ten days.
