Citizen Health

What Citizen Health does

Citizen Health is a healthcare technology company that builds an AI-powered patient advocacy platform for individuals living with rare and complex diseases, along with their caregivers. The platform aggregates patient medical records across providers, uses natural language processing, generative AI, and computer vision to translate complex clinical information into plain language, records and summarizes medical visits via audio capture, drafts insurance and school documentation, and connects users to disease-specific patient communities. The core product is delivered as a free iOS application and web portal; the patient-facing tier is always free, and there is no consumer pricing. SOC2 Type I certification and a dedicated Chief Privacy Officer (Deven McGraw) underpin the platform's data handling practices.

The business model is B2B2C. The company acquires patients through a community-led motion, leveraging partnerships with 15+ patient advocacy foundations (FOXG1 Research Foundation, CASK Warriors, CACNA1A Foundation, ADCY5 Foundation, Coalition To Cure CHD2, Gallbladder Cancer Foundation, and others) to drive organic sign-ups across 350 disease communities. With patient consent, longitudinal and de-identified data powers natural history studies and is licensed to pharmaceutical and life sciences customers; the company has disclosed 16+ pharma customers and a strategic partnership with UCB for epilepsy and rare disease drug development. A specialized AI Advocate for Gallbladder Cancer was launched in February 2026 in partnership with the Gallbladder Cancer Foundation as a vertical extension.

Citizen Health is headquartered in San Mateo, California, was founded in 2017, and operates with 11-50 employees. The company is venture-backed with $44.5M disclosed across a $14.5M seed round in November 2024 led by Transformation Capital (with Wavemaker 360 and the Chan Zuckerberg Initiative) and a $30M Series A in August 2025 led by 8VC (with Transformation Capital and Headline). The co-founders are CEO Farid Vij and CBO Nasha Fitter, both of whom are rare disease caregivers; the leadership team also includes a CTO (Daniel Wang), a Chief Privacy Officer, a Certified Genetic Counselor leading clinical strategy, and a product lead whose child has a rare genetic disorder.
