Sachin Bansal and Binny Bansal were stuck at the same lab in IIT Delhi, trying to complete their delayed projects when they met. In September 2007, bored with their jobs at Amazon, they pooled in ₹4 lakh and started Flipkart, selling books that were easy to list, ship and find vendors for. In the early days, the Bansals rode around Bengaluru on bikes every alternate day, delivering orders. They also sourced the books, for which they sometimes scoured through warehouses for hours. By 2012, Flipkart had become a unicorn, and by 2013-14, it set new benchmarks for online retail in India by building an unrivalled logistics and supply chain operation. In 2018, US retailer Walmart acquired Flipkart for $16 billion, and led to the exit of the founders.
