Byju's founder Byju Raveendran is India’s newest billionaire

India’s newest billionaire is a former classroom teacher who developed an education app that’s grown to a valuation of almost $6 billion in about seven years. Byju Raveendran joined the rarefied club after his Think & Learn Pvt scored $150 million in funding earlier this month. That deal conferred a value of $5.7 billion on the company in which the founder owns more than 21%, people familiar with the matter said.
