About
Particle Health is a health data exchange company founded in 2018 that provides developers and healthcare companies with a single API to access patient clinical records from national health information networks including CommonWell, Carequality, and others. The company abstracts the complexity of connecting to dozens of regional health information exchanges and national networks behind a simple developer-friendly API, enabling healthcare applications to retrieve longitudinal patient records including medical history, lab results, diagnoses, and medications from any participating provider. Particle raised $60M and serves digital health companies, telehealth platforms, health plans, and healthcare analytics firms that need access to real-world patient data to power clinical decision support, care management, and value-based care programs. The company provides HIPAA-compliant data access with identity verification and purpose-of-treatment validation to ensure appropriate use of patient records. Particle's API approach reduces the time and cost for healthcare companies to build clinical data infrastructure from months of complex integrations to days of API implementation.
London and New York AI platform automating insurance prior authorization; reads patient clinical records to extract evidence justifying medical necessity and cut treatment delays.
About
Anterior is a London and New York-based healthtech company that applies AI to automate the prior authorization process, one of the most burdensome administrative tasks in U.S. healthcare. Prior authorization requires physicians to submit clinical evidence to insurance companies justifying the medical necessity of treatments, procedures, or medications — a process that consumes significant physician and staff time and causes treatment delays that harm patient outcomes. Anterior's AI reads patient clinical records, identifies the relevant clinical criteria required by the insurer, extracts supporting evidence from the patient's history, and generates complete prior auth submissions automatically. The platform also predicts approval likelihood and flags cases likely to require clinical review, helping health system staff prioritize their work. Founded in 2022, Anterior raised funding from investors including Sequoia Capital and has rapidly signed health system customers facing acute prior authorization burdens. The company's approach addresses a systemically inefficient process that costs the U.S. healthcare system an estimated $35B annually in administrative waste.
