Overview

Citizen Health builds a patient-centered platform that combines data, AI, and community to act as a personalized AI advocate. The product integrates a patient’s complete medical history alongside cohorts of similar patients to surface practical guidance for clinical decisions and everyday challenges, beginning with rare and complex conditions. Patients choose to share their data in exchange for value, while biopharma and researchers gain access to consented populations and regulatory-grade real-world data that can shorten timelines for evidence generation and drug development. The company’s stack spans healthcare interoperability standards such as FHIR, large language models and retrieval-augmented generation, scalable microservices, and secure data pipelines, with an emphasis on privacy and HIPAA-aligned practices. Citizen Health describes a mission-driven culture that values speed, ownership, and clear documentation, alongside empathy, diversity, and learning. Roles range from record collection and data operations to backend engineering and commercial partnerships. The company is led by repeat founders and backed by investors including 8VC, Transformation Capital, and Headline Ventures.
