As a diabetic himself, Vineet Singal knows first-hand that being on top of his condition is the key to staying healthy. That’s what inspired him to create his business Anjna Patient Education when he was a senior at Stanford. The company helps people stay in closer contact with their health providers with a simple, text-messaging app that sends appointment and medication reminders and tips on eating better. It’s already been picked up by a few California hospitals. They pay Anina for the app, and then provide it free to their low-income clients. Singal’s app even snagged him a $40,000 Hitachi Foundation Yoshiyama Young Entrepreneurs Program award this year.
