What believers are saying

  • Ascertain raised $10 million Series A from Deerfield Management and Northwell Health in April 2025.
  • The Oncology Institute cut authorization submission time over 80 percent and saved staff hours.
  • Ascertain won 2026 New York Digital Health 100 recognition, strengthening hiring and sales momentum.

What critics are saying

  • Prior authorization AI faces entrenched rivals like Waystar, Cohere Health, and Infinitus.
  • Ascertain still depends on Northwell and Deerfield for distribution and credibility.
  • If payer portals block automation, Ascertain's economics collapse before 2026 scaling gains.

What makes Ascertain unique

  • Northwell Health and Aegis Ventures built Ascertain as a company-creation platform in 2022.
  • Its agentic AI handles end-to-end prior authorization, not isolated workflow fragments.
  • The Oncology Institute deployment hit live production in eight weeks across 100-plus clinics.
