In 2013, one of my best friends, Andrew Le, started a company with three others –  Adam Lathram, Nathanael Ren, and Eddie Reyes – seeking to revolutionize the healthcare industry, specifically how people used the internet to self-diagnose. In 2015, they landed on the name Buoy. Their goal was simple, really – to build a healthcare companion that provides people more reliable, tailored information than what was currently available on the internet (for example, WebMD). What it does is very much like texting a real doctor: after telling it what’s going on, Buoy’s algorithm automatically asks you twenty questions to figure out what diagnoses are most likely and what to do about it (stay at home, see a doctor, etc). If needed, Buoy can even connect you with doctors nearby.
