Every forty seconds, a stroke begins. The first hour decides whether the next thirty years look like recovery — or a second life spent in rehabilitation.
For decades the question has been how quickly can we reach a hospital. We think the better question is how quickly the hospital can reach you.
The answer is already in your pocket: a camera, a microphone, a neural engine. We taught it to do the one thing an ER team can't — notice the first second.

Stroke is the world's most expensive preventable emergency — and the one category where a thirty-second head start rewrites the bill, the outcome, and the rest of a life.
No wearables. No new hardware. code:blue uses the existing camera and microphone on any phone, laptop, or webcam — quietly, wherever you are.
Nothing leaves without your permission. If code:blue detects something, you choose who gets notified — a family member, a caregiver, or both.
Models trained on real stroke footage in partnership with UCSF Health. Every detection model is reviewed by our clinical advisors before deployment.
When code:blue detects a possible stroke, it notifies your trusted circle and contacts emergency services — with your location and condition already shared before help arrives.
Building a product that sits between clinical medicine, consumer software, and the FDA requires a specific, unusual mix of people. We went and got them.










If you invest in healthcare, early-stage AI, or consumer devices that touch regulated medicine — or if you run a health system thinking about pre-hospital triage — there's a short window to get on the right side of this one.
