# Buoy Health

> Buoy Health is a Boston-based digital health company that built an AI-powered symptom checker and care-navigation platform. Founded in 2014 out of Harvard Innovation Labs, Buoy lets people describe how they feel in a chat that mimics a conversation with a doctor, then steers them toward the right next step - from self-care at home to the ER - using an algorithm trained on thousands of medical studies. The company sells its navigation platform to employers, health plans and providers while keeping the consumer symptom checker free.
