Consumer health platform with 160+ lab tests and clinical imaging access

Technology, Information and Internet United States 11–50 employees Founded 2022 Privately Held

Function Health operates a consumer-facing health platform combining lab testing, advanced imaging, and clinician-led insights. The tech stack reveals a consumer-first mobile orientation (Swift, Kotlin, React Native) paired with AI/ML infrastructure (LangGraph, PydanticAI, DSPy, LlamaIndex) and clinical-grade backend systems (Kubernetes, multi-cloud deployment across AWS/GCP/Azure). The engineering-heavy hiring mix and active projects around real-time health data access and clinical workflows suggest the company is scaling beyond initial product-market fit into operational complexity — particularly around member experience and workflow automation.
