Infinitus Systems tackles one of healthcare's most invisible but enormous burdens: the millions of phone calls that staff make to insurance payers to verify benefits, check prior authorizations, and resolve administrative questions. These calls are repetitive, time-consuming, error-prone, and expensive, yet essential to getting patients treated and providers paid. Infinitus automates them with AI voice agents that can actually conduct these conversations end to end.
The company's system is deliberately built for the high stakes of healthcare. It pairs a multimodal AI voice engine with human-in-the-loop guardrails — so humans can supervise and correct in real time — and an extensive medical and payer knowledge graph that gives the AI the domain context needed to navigate complex insurance conversations. This combination of automation plus oversight is Infinitus's answer to the accuracy and compliance demands that make naive automation risky in healthcare.
Infinitus has processed millions of healthcare phone calls, freeing clinical and administrative staff from hours on hold and reducing the cost and delay of manual benefit verification and authorization workflows. Its customers include leading healthcare and pharmaceutical organizations that depend on these processes at scale.
In November 2024 Infinitus raised a $51.5M Series C led by Andreessen Horowitz, with Memorial Hermann Health System joining alongside existing investors Kleiner Perkins, Coatue, and GV (Google Ventures), bringing total funding to roughly $103M. a16z managing partner Scott Kupor joined the board. The company framed the round around the strength of its AI guardrails, positioning trustworthy, supervised automation as the key to scaling voice AI in healthcare operations.
