What Ciitizen does
Citizen Health (formerly Ciitizen) is a Palo Alto-based patient technology company founded in 2017 that operates an AI-powered platform aggregating medical records and providing advocacy tools for rare disease patients and their caregivers. Its core product, the Citizen Health Platform, combines FHIR-compliant medical record integration, natural language processing for clinical record interpretation, audio capture during medical visits, and secure de-identification infrastructure. The flagship AI Advocate feature records and transcribes medical visits, producing structured summaries and next-step recommendations, while the native iOS application extends the platform to mobile caregiver workflows. The company is SOC 2 Type I certified (verified by Thoropass) and operates with a dedicated Chief Privacy Officer, signaling a compliance posture appropriate for handling sensitive health data.
The platform is offered free of charge to patients and caregivers, distributed via self-serve web sign-up and the Apple App Store, and is trusted by more than a dozen rare disease patient advocacy organizations including the FOXG1 Research Foundation, CASK Warriors Foundation, and ADCY5. Citizen Health generates revenue through a data-monetization model: thousands of consented patients contribute de-identified data that powers Natural History Studies and other research outputs sold to pharmaceutical companies and academic researchers, with outputs cited in peer-reviewed journals including Brain (2023). The company has raised approximately $20 million in disclosed equity financing (seed and Series A led by Andreessen Horowitz, with S32, Verily, Mubadala Capital Ventures, and Schox Venture Capital also participating) and acquired Stella Technology in May 2021 to deepen interoperability capabilities.
The company employs between 11 and 50 people and is led by CEO and co-founder Farid Vij, CBO and co-founder Nasha Fitter (also co-founder of the FOXG1 Research Foundation), CTO Daniel Wang, and Chief Privacy Officer Deven McGraw — a leadership team distinguished by direct personal experience with the rare disease patient journey the platform serves.

Ciitizen competitors and assessment
Company assessmentDirect peers
- PicnicHealth: Most direct peer. PicnicHealth aggregates patient medical records (with patient consent), builds de-identified datasets, and partners with pharma to run observational research, including in rare disease. Uses similar patient-mediated record collection and data monetization model targeting life sciences customers.
- AllStripes (now Tisento): Direct peer focused specifically on rare disease. Patients contribute medical records that are de-identified and used to generate real-world evidence for pharma rare disease research. Competes head-to-head with Citizen Health for both rare disease patients and life sciences partnerships.
- RARE-X: Nonprofit patient-mediated data platform for rare disease, also aggregating patient records with consent for research use. Competes for the same patient advocacy relationships and uses a similar consent-driven data sharing model.
Broad incumbents
- PatientsLikeMe: Earlier-generation patient community and self-reported health data platform that pioneered patient-generated data sharing with researchers. Operates at a broader scale than Citizen Health but with less structured EHR data; useful comp for patient-side data monetization.
- 23andMe: Consumer health data company that monetizes de-identified genetic and phenotypic data through pharma partnerships (e.g., GlaxoSmithKline). Demonstrates the consumer-data → research-revenue model at large scale, though focused on genetics rather than full medical records.
- Invitae: Genetic testing and data company with a rare disease focus that aggregates patient data and partners with pharma. Operates at greater scale and has a broader service portfolio, but the rare disease data partnership motion overlaps with Citizen Health's.
- Epic MyChart: Dominant EHR patient portal with distribution to hundreds of millions of patients across US health systems. Provides basic patient-mediated access to medical records and represents the default alternative against which Citizen Health must differentiate.
- Apple Health Records: Consumer-facing personal health record feature within Apple Health, with FHIR-based aggregation from participating health systems. Provides similar patient-mediated record access to iOS users at massive scale, competing for the same iPhone-using patient demographic.
Emerging players
- Genome Medical: Telehealth genetic counseling service that helps patients understand genetic results and rare disease diagnoses, partially overlapping with Citizen Health's clinical strategy (Elli Brimble is a Certified Genetic Counselor). Adjacent in the rare disease patient journey.
- Truveta: Health system-backed platform aggregating de-identified patient data from providers for life sciences research. Competes with Citizen Health on the life sciences buyer side, though sourced from providers rather than patient-mediated consent.
