About the company

Junction is a healthcare infrastructure platform that unifies wearable, remote-patient-monitoring (RPM), and laboratory data through a single developer-oriented API. It lets digital health products order lab tests and read real-time device streams without building hundreds of individual integrations. The API connects to hundreds of wearables and RPM devices (including Apple, Fitbit, Oura, and Dexcom) and majorUS lab networks like Labcorp and Quest, supporting in-clinic, at-home kits, and mobile phlebotomy workflows used by digital health, wellness, insurer, and CRO customers. The platform already handles large volumes of lab tests and millions of connected devices for apps focused on chronic care, personalized treatment, and clinical research. Its goal is to expand its API network and scale the platform to make it easier for developers to access lab results and device data, enabling faster, data-driven health solutions.

Simplify's Take

What believers are saying

  • June 2026 UTI diagnostics launch expands beyond chronic care into acute testing.
  • Avon Health's embedded EMR workflows validate enterprise demand for Junction's infrastructure.
  • March 2025's $18 million Series A funds network expansion and customer acquisition.

What critics are saying

  • Epic integrated Galleri in April 2026, commoditizing Junction's ordering layer by year-end.
  • GRAIL lacks broad Medicare coverage until 2029, limiting Junction's screening revenue.
  • If device or lab partners bypass Junction, the API loses its core moat.

What makes Junction unique

  • June 2026: Junction embeds labs, wearables, and diagnostics through one API.
  • April 2026 GRAIL partnership widens Galleri access across digital health workflows.
  • 140-plus customers and 500,000 annual tests prove real operational integration.

Junction partners with GRAIL to enable multi-cancer screening through diagnostic platform

Junction, a diagnostic testing infrastructure platform, has announced a collaboration with GRAIL to support access to the Galleri multi-cancer early detection test across digital health platforms and clinical organisations. Through Junction's infrastructure, healthcare providers can integrate Galleri into their workflows with unified ordering, embedded physician networks and streamlined operational support. The Galleri test is a blood test designed to detect signals from over 50 cancer types, many lacking recommended screening options. Junction's platform enables organisations to order the Galleri test directly, support multi-state clinical operations and manage complex testing workflows. The collaboration aims to simplify the operational steps around offering Galleri, making it easier for providers to integrate the test into care delivery. Junction provides infrastructure that powers healthcare platforms through a single API.
