Infinitus Systems vs Prosper AI
The two vendors automating the phone call nobody wants to make, and the difference is how many directions they point. Infinitus is specialised on the outbound payer call: dialling, navigating menus, holding, extracting benefits, authorisation status and claim status, then writing structured results back into the systems that need them, with a knowledge graph of payer specific rules underneath. Prosper does the payer call too and adds the inbound patient side, scheduling, intake and billing questions, on a single voice layer, and it names its model provider, which almost nobody here does. For a large system where the payer call queue is the bottleneck and patient access is already solved, Infinitus is the deeper specialist. For a group that wants one voice vendor covering both directions, Prosper is the more economical shape.
- It calls the payer. The agent dials, navigates the interactive voice menus, waits on hold and completes benefit verifications, authorisation checks and claim status inquiries, which is the specific administrative bottleneck almost nothing else attacks directly.
- Call outcomes are converted into structured data written back into systems rather than left as a transcript, so the output is usable by the revenue cycle rather than by a human reading notes.
- SOC 2 Type II with the type stated by the company itself, and an architecture described concretely as a knowledge graph of payer specific rules rather than as a general assistant.
- It works both directions on one platform, calling payers and also handling patient scheduling, intake and billing questions, so a practice buys one voice layer rather than two.
- It names its underlying model provider, which very few vendors in this index do, and publishes the strongest protected health information position in this category.
- SOC 2 Type II with the type named and independently audited, plus deployment detail that is unusually complete for a voice product.

Both vendors run autonomous agents on live payer calls, which raises two questions neither answers fully. First, recording consent: several states require all party consent and these calls are recorded on both ends, which is the deploying organisation's obligation rather than the vendor's.
Second, what happens when the payer representative gives wrong information, since the structured output that lands in the revenue cycle inherits whatever was said on the call and neither vendor publishes an error or correction rate. Neither publishes pricing, and neither publishes a governance framework, bias evaluation or subgroup performance analysis, which matters because speech recognition performance varies by accent and dialect on both sides of the call.
