StepStone Group, a private equity firm, led a $200m Series E round in Zepto, a 10-minute grocery delivery service provider, with participation from Goodwater Capital, Nexus Venture Partners, Glade Brook Capital and Lachy Groom. The latest funding gives Zepto firepower in a highly competitive segment, where the company is jostling for position with the likes of Zomato-owned Blinkit, Swiggy Instamart and Tata-owned BigBasket. The company will primarily use the funds to invest in growth while going for operating profitability in the next 12-15 months.
