Solve a woman's problem — this was the challenge which Divya Krishnan, Sundar Jagannathan and Senthil Kumar received at a hackathon. Kumar's sister was pregnant then and the trio decided to develop a wearable device that would remind her to take her pills on time and go for her check-ups. This was the starting point for JioVio, a start-up that provides IoT/bluetooth-based predictive maternal care.
