Billionaire Sridhar Vembu's wife, Pramila Srinivasan, said she used her income to support Vembu build Zoho after he quit his job. "I felt shocked to learn only after he filed for divorce that he claimed to own just 5% of the company he'd spent our marriage building," Srinivasan said. Vembu's sister Radha is Zoho's largest shareholder, with a 47.8% stake.
