About Altair Health
Summary
Altair Health runs end-to-end medical billing for independent physician practices, replacing in-house billing staff and outsourced billing services. An AI agent handles claim submission, prior authorizations, eligibility checks, and denial appeals by checking every action against a formal, prover-verified model of each insurer's current policies. Human billers step in only when the prover flags an exception, so claims go out clean and denials are worked immediately rather than queued.
Business model
A fee taken on collections managed on behalf of each practice.
Go-to-market
Independent practices connect their EHR and clearinghouse directly through a self-serve onboarding flow, with no implementation work required from front-desk staff.

Stripe for medical billing
Altair is an AI-native medical billing service for independent practices. We take over a practice's billing end to end and get doctors paid by insurers. AI does the work; our billers handle the exceptions. That can only work if a practice can trust an agent alone with its revenue. So we formalized insurers' billing policies and put a theorem prover under the agent. Before the agent acts on a claim, the prover checks the action against that insurer's policies, and anything that fails goes to one of our billers. Every claim teaches Altair how each insurer behaves, so the longer we run a practice's billing, the better we predict what its insurers will pay, deny or delay. We're building the default way a new practice gets paid: a doctor connects their EHR and bills clean from the first patient, completely self-serve and on auto-pilot. Altair will be the financial platform every independent practice in America starts on and stays on.
