Where Infinitus Systems wins
Phone call automation at scale
Infinitus has built sophisticated voice AI that can navigate IVR systems and speak with payer representatives on behalf of providers.

With $102.9M in total funding including a $51.5M Series C led by Andreessen Horowitz, Infinitus has the resources to invest in voice AI research and payer coverage expansion. Their Google Cloud partnership strengthens the underlying AI infrastructure.
Where AuthAnnie wins
Denial appeals, not just phone calls
Infinitus automates the phone call — checking PA status, verifying benefits, following up on claims. AuthAnnie addresses what happens when those claims are denied: generating evidence-based appeal letters, analyzing denial patterns, and tracking revenue recovery. Phone automation and denial management are complementary, not interchangeable.
Built for physician practices
Infinitus targets large health systems and revenue cycle management companies. Their enterprise pricing and implementation model is designed for organizations processing millions of transactions. AuthAnnie is purpose-built for physician practices — from five-provider groups to multi-location practices — with pricing and workflows that match practice-scale operations.
Payer-specific denial intelligence
Knowing a claim was denied is the starting point. AuthAnnie analyzes why claims are denied by specific payers, identifies denial patterns across your practice's payer mix, and generates appeals that address the exact deficiency each payer cited. Infinitus can tell you a claim was denied. AuthAnnie helps you overturn it.
Revenue recovery measurement
AuthAnnie tracks every appeal from submission through resolution, measuring revenue recovered by payer, denial type, and service category. This data drives both immediate revenue recovery and long-term denial prevention. Infinitus provides call completion data but doesn't track appeal outcomes or revenue recovered.
AuthAnnie vs Infinitus Systems
Infinitus solves a real problem — the hours practices spend on hold with insurance companies. Their voice AI is impressive technology backed by serious capital. But automating phone calls and managing denials are different problems. Infinitus can check your PA status and verify benefits faster. AuthAnnie can tell you why your claims are being denied, generate the appeal that overturns them, and track the revenue you recover. For physician practices, the denial management gap is where the revenue is. If your biggest problem is phone hold times, Infinitus is worth evaluating. If your biggest problem is denied claims, AuthAnnie addresses that directly.
