Ascertain is a healthcare technology company that builds an agentic AI platform to automate administrative workflows including prior authorizations, referrals, eligibility checks, care coordination, and revenue cycle operations for health systems, payers, and provider groups. Founded in 2022 as a partnership between Northwell Health and Aegis Ventures, and backed by Deerfield Management, Ascertain uses human-in-the-loop AI agents that integrate with existing enterprise systems to deliver measurable ROI in under 90 days.

The platform automates complex, forms-heavy workflows across prior authorizations, eligibility verification, care coordination, discharge planning, and payer communications while maintaining human-in-the-loop oversight and built-in traceability. Proven results include a 95% reduction in prior authorization workload across 100+ oncology clinics with The Oncology Institute, an 80% reduction in user clicks and 67% faster authorization submissions at Northwell Health, and a partnership with Cardiovascular Associates of America covering 460+ cardiologists across 100+ locations.
