What is Infinitus?
Infinitus is a voice AI platform that automates outbound calls to payers for prior authorization status checks, benefits verification and other follow-up tasks. Founded in 2019 and based in San Francisco, it is sold to teams that lose significant staff time to phone-based payer follow-ups, as a layer on top of an existing prior authorization workflow.
How much does Infinitus cost?
Infinitus does not publish per-user prices. Like the other prior authorization vendors in this category, it sells custom enterprise pricing by quote. Because it automates one step, payer calls, budget for it alongside the prior authorization system it will work with, and size the quote by the volume of payer calls your team makes.
How do Infinitus voice AI agents work?
Infinitus voice AI agents place outbound calls to payers and work through IVR menus, hold queues and live conversations to retrieve prior authorization status and benefits information. The results return to staff as structured data, so staff spend less time in IVR menus and hold queues. Infinitus targets payer calls, often the most time-consuming step in prior authorization.
Is Infinitus a full prior authorization platform?
Infinitus is not an end-to-end prior authorization platform; it is a specialized calling layer. It automates payer follow-up calls but does not replace the rest of the workflow, so it works best added to an existing process and paired with a broader authorization management system.

Infinitus FAQ
Does Infinitus do benefits verification?
Yes. Besides prior authorization status checks, Infinitus voice agents make benefits verification calls to payers and return the results to staff as structured data. Both are phone-based follow-ups that otherwise keep staff in IVR menus and hold queues.
What is the difference between Infinitus and Infinx?
Infinitus automates payer phone calls with voice AI agents and returns structured data to staff. Infinx pairs prior authorization software for triage, payer monitoring and follow-up tasks with service teams that handle complex payer interactions and backlog clean-up. Infinitus is a narrower layer; Infinx covers more of the workflow, with people.
What is the best alternative to Infinitus?
For payer follow-up, Infinx is the closest alternative: it manages follow-ups with automation and service teams rather than voice AI. Teams that want one platform for the whole workflow can look at Silna Health, and practices whose bottleneck is referral intake can look at Tennr.
