Mukesh Ambani chairs and runs $74 billion (revenue) Reliance Industries, which has interests in petrochemicals, oil and gas, telecom and retail. Reliance was founded by his late father Dhirubhai Ambani, a yarn trader, in 1966 as a small textile manufacturer. After his father's death in 2002, Ambani and his younger sibling Anil divvied up the family empire. Reliance sparked a telecom price war with the launch of 4G phone and broadband service Jio in 2016. Today, investors in Jio include Google and Facebook. Ambani is pivoting Reliance into green energy. The company will be investing $80 billion over the next 10-15 years on renewable energy and building a new complex next to its refinery.
