Overview
Infinitus builds AI voice agents that place and navigate phone calls with health insurers on behalf of clinic staff — handling benefit verification, prior authorization, and other revenue-cycle phone workflows. Its FastTrack copilot navigates legacy IVR menus and hold queues so front-desk teams spend less time on payer phones. The company raised a $51.5M Series C in 2024 led by Andreessen Horowitz, with Kleiner Perkins, Coatue, and GV among returning investors. Scott Kupor joined the board at that round.
Why Infinitus is interesting
Payer phone calls are the least glamorous bottleneck in healthcare admin — Infinitus bets guardrailed voice AI can navigate IVR hell faster than offshore BPO, with Scott Kupor on the board after a $51.5M Series C.

Competitive landscape
Edge: Purpose-built for legacy payer IVR navigation — not generic call-center AI — with guardrails tuned to HIPAA-sensitive healthcare workflows.
Healthcare admin automation is crowded, but payer phone calls remain stubbornly manual because IVR systems vary by plan. Infinitus's wedge is voice agents trained for this specific workflow rather than generic RPA. Risk: payers may block automated callers or digitize APIs faster than voice AI scales.
