Ascertain is a New York-based agentic AI platform automating prior authorisations, referrals, eligibility checks and care coordination for healthcare organisations.
Ascertain builds an agentic AI platform for healthcare administration. Founded in 2022 and based in New York, the company automates end-to-end workflows in care management and revenue cycle operations for health systems, including prior authorisations, referrals, eligibility checks and care coordination. The platform operates across existing systems and is designed to adapt to complex real-world workflows, deploying in weeks rather than months.
Results reported in pilots include an 80% reduction in user clicks and a 67% cut in the time taken to submit authorisations. The technical domains span agentic AI, workflow and process automation, and healthcare-specific applications in revenue cycle and care management.
Ascertain was founded in partnership with Northwell Health, New York's largest healthcare provider, alongside Aegis Ventures, with backing from Deerfield Management. It is led by chief executive Dr. Mark Michalski, a radiologist. The company raised $10 million in a Series A round and states a mission of reducing the administrative burden on clinicians.
