Layer Health builds an enterprise AI platform for healthcare chart review. It uses a healthcare-focused large language model (LLM) to analyze longitudinal patient charts, enabling clinicians and life sciences teams to answer complex clinical questions, automate clinical registries, and generate quality measurements. The system works by processing patient charts through modules that support registry data submission, real-world evidence abstraction, and patient registries, with emphasis on accuracy, configurability, and security. It differentiates itself from competitors through healthcare-specific validation, enterprise-grade security/compliance, and a broad set of use cases tailored to both health systems and life sciences, enabling faster, more reliable data analysis with fewer administrative burdens. Its goal is to streamline chart review, improve data quality, and free clinicians to focus more on patient care by delivering actionable insights and reliable data faster.

Simplify's Take

What believers are saying

  • Layer Health raised $21 million Series A in March 2025, extending runway.
  • Froedtert reported 65% faster abstraction, strengthening sales claims and references.
  • ACS and Johns Hopkins partnerships expand into research and oncology registries through 2026.

What critics are saying

  • Epic, Optum, and point-solutions can bundle chart abstraction into broader contracts by 2027.
  • Validation dependence on hospital-specific workflows slows rollouts and exposes accuracy failures.
  • If registry buyers distrust LLM evidence trails, Layer Health becomes a pilot-only vendor.

What makes Layer Health unique

  • MIT-spun Layer Health automates clinical registry abstraction with longitudinal-chart LLMs.
  • Intermountain Health deployment spans 33 hospitals, proving enterprise workflow depth.
  • Johns Hopkins Medicine chose Layer Health for multi-year registry automation in 2025.
