Junction

What Junction does

Junction (formerly Vital, originally Amino Collective) is a healthcare infrastructure company that operates a unified API connecting 300+ wearable devices, medical devices, and a nationwide lab testing network spanning all 50 US states. The platform is built around three core products: the Device API, which normalizes data from wearables (Fitbit, Garmin, Oura, Apple HealthKit, WHOOP, Dexcom) and medical devices (CGMs, blood pressure monitors) into standardized schemas accessible via multi-language SDKs (Java, Go, TypeScript, Python) and mobile SDKs (iOS, Android, Flutter, React Native); the Lab Testing API, which provides test ordering, kit logistics, and results delivery across walk-in, at-home kit, and mobile phlebotomy collection methods; and Horizon AI/Junction Sense, which transforms raw device data into structured, clinically relevant insights with predictive AI capabilities on the roadmap. The company sells to three primary segments: virtual-first and digital health clinics, consumer diagnostics and wellness platforms, and EHR/EMR/healthcare SaaS providers. Revenue is generated through a tiered subscription model (Launch at $0.50/user/mo with a $300 minimum, Grow at under $0.50/user/mo, and Scale at custom enterprise pricing with multi-year contracts) supplemented by transaction-based lab testing fees on the Scale tier. The go-to-market is hybrid, combining a self-serve developer portal with sandbox access and an enterprise field sales motion for larger deployments, backed by SOC 2 Type 2, ISO 27001, HIPAA, and GDPR certifications.
