Flipkart Co-founder Sachin Bansal, who exited the company after Walmart's $16-billion acquisition, said in an interview that he "never wanted to sell" Flipkart and never imagined he wouldn't be with the firm. Bansal, who co-founded Navi Technologies months after leaving Flipkart, added that he plans to be with this venture for next 20 years and has put his "all in".
