Our mission is to empower the world’s clinicians and caregivers with the best learning experience possible.

Our Founders

Ryan Haynes and Shiv Gaglani started building Osmosis as medical students at Johns Hopkins.

Outside of the classroom, they knew there had to be a better way to learn medicine more effectively. What began as a tool to help Shiv, Ryan, and their classmates has transformed into the Osmosis of today, a comprehensive platform that helps people around the world understand health more thoroughly.
