What prompted Azim Premji, one of the richest Indians, to give away 92% of his wealth over the past two decades to a foundation meant for philanthropic work?

The two former Mint journalists bring their rich experience as business journalists to bear in their book, Azim Premji: The Man Beyond the Billions, as they speak to several associates, employees and friends of the Bengaluru-based billionaire about his company, Wipro, the IT sector and philanthropy.
