Zomato Co-founder Mohit Gupta has resigned after a four-and-half-year stint at the company. It's the third high-profile exit from the food delivery company in recent weeks. Zomato's new initiatives head and former food delivery chief Rahul Ganjoo had resigned earlier this week while Siddharth Jhawar, head of Zomato's Intercity Legends service, announced he had left the company a week back.
