What Primary Bio does
Primary Bio, operating commercially as Primary.Health and legally as Primary Diagnostics, Inc., is a San Francisco-based digital health platform company founded in 2020 during the COVID-19 pandemic to deliver testing, vaccination, and public health management software to schools, public health agencies, employers, and healthcare organizations. The company's core offering is a multi-product interoperability platform organized around three pillars — Health (patient management, registration, scheduling, and reporting for testing and vaccination programs), LabConnect (a LIMS-agnostic integration engine and lab portal for health data exchange and surveillance), and Analyze (data ingestion, dashboards, and custom reporting) — supplemented by vertical modules including Newborn Screening Case Management, Immunization Management, Sexual Health, CLIA Waiver point-of-care testing, Digital Clinical Health, Diagnostics, and Indoor Air Safety (co-developed with Poppy Health). The technical architecture emphasizes integration with state Immunization Information Systems (CAIR, CIIS, MIIC, ImmTrac2, WA-IIS), School Information Systems (Aeries, OneRoster), and a broad set of labs and insurance partners, positioning interoperability rather than AI/ML as the core differentiator. Platform delivery is supported by a HIPAA-compliant, HITRUST CSF-certified cloud infrastructure and the Primary Health Pass mobile application.
Primary.Health generates revenue through a combination of subscription-based software licensing (multi-year contracts with schools and public health agencies via tiered packages — State Program, Honor Roll, Dean's List) and transaction-fee revenue from administered testing and vaccination services, including self-pay consumer testing paid via major card networks. The go-to-market is enterprise field sales to government buyers (anchored by the California Department of Public Health, which has designated the company as the platform for a statewide program covering 5,500+ school locations), supplemented by channel partnerships with state health departments, healthcare providers (Optum Health, UCSF), and integrators. The company serves 4,000+ schools across 25 U.S. states, has administered 13.7M+ tests and 1.5M vaccines, and operates across 10K+ locations with 51-100 employees, led by co-founder and CEO Andrew Kobylinski, CTO and co-founder Chris Zhu, and Executive Chairman Roushan Zenooz. Only one funding round (a 2020 Yes VC-led round) is disclosed in the source material, indicating a capital-efficient operating posture relative to typical venture-scale healthtech peers.
