Junction provides infrastructure for healthcare organizations, making patient data accessible, actionable, and automated across lab testing and device integrations. Our mission is to reduce the cost of managing chronic disease by two orders of magnitude.
Healthcare is in a crisis, help us fix this for the humans behind the results. With more and more data being collected from wearables, lab tests and patient-doctor conversations, we’re entering an era where data is abundant. We need people like you who are passionate about how technology can supercharge healthcare.
We’ve got some of the greatest hearts and minds from Babylon, Ro Health, SpaceX, Instacart and Monzo - working to solve one of the biggest challenges of our time: making personalized, proactive, and affordable healthcare a reality. Backed by Creandum, Point Nine, 20VC, YC, and leading angels, we’re connecting millions already.
