Uday Kotak, the founder of Kotak Mahindra Bank, has stepped down as the bank's Managing Director and CEO. Under his leadership, the bank grew from a small bill-discounting business to India's third-largest private lender by market value. Kotak's knack for spotting financial opportunities, such as car financing and forming partnerships with global firms, helped the bank thrive. He also made banking look cool and built an intelligible brand through innovative marketing campaigns.
