Zomato and Swiggy reportedly held talks for a potential acquisition of Zepto, a 10-minute grocery delivery app founded by 19-year-old Stanford dropouts, a few months ago, which did not fructify. Zomato approached Zepto with a nearly $1-billion buyout offer, while talks with Swiggy didn't reach offer stage, Moneycontrol reported citing sources. Zepto said it won't comment on speculative stories.
