Dheeraj Gupta started Jumbo King Foods Pvt. Ltd. in Mumbai in 2001 to sell packaged Indian sweets. Inspired by a book on McDonald's, he realized he could start a fast food chain selling vada pav. He opened his first outlet called Chaat Factory near Malad station, later renamed Jumbo King. Through word of mouth and branding strategies like celebrating Vada Pav Day, the company grew to 30 outlets in Mumbai and other cities, serving about 40,000 customers daily. Gupta aims to expand Jumbo King across Maharashtra and Gujarat with over 100 outlets and a projected annual turnover of Rs. 60 crores by 2008-09.
