BYJU RAVEENDRAN, 

Byju Raveendran began by holding informal classes at cafes to help friends crack the business school entrance exam. Today, he heads India’s largest education technology firm, Byju’s, which runs a learning app for everybody from school students to competitive exam candidates. Byju Raveendran first took the Common Aptitude Test (CAT) in 2003 and came out with a 100 percentile—so he decided to take the test again to make sure it wasn’t a fluke. It wasn’t. He maxed it again. Despite his scores, he chose not to go to management school and opted for teaching instead. Wise decision. Fifteen years down the road, 37-year-old Raveendran heads India’s largest education technology firm, Byju’s, that runs a popular personalised mobile learning app offering study material for school students and competitive exam candidates. The app has 14 million registered students and is growing by the day
