Zepto could surpass DMart in sales in the next 18-24 months, Co-founder Aadit Palicha said. "DMart is a $30 billion company and they're only 4.5X our size in sales...If we continue to execute well, we will continue to grow 2-3X every year," said Palicha. He also said that grocery is bigger than all the categories that Amazon and Flipkart service.
