Byju Raveendran has just too much energy. Like, shake your legs constantly and fidgeting with stuff on the table; a pen, an iPad, sort of energy. Also, he is quite the looker. Tall, about six feet, dark, pumped out chest, body-hugging black tee and blue jeans. It adds to his whole persona that Byju has cut his teeth in the art of performing; for years, he has been a sought after teacher and taught mathematics to a crowd of thousands. Tens of thousand. So, fairly apt then, that right now, at the corporate office of Byju’s at IBC Knowledge Park in Bengaluru, inside a large conference room, seated at the head of a long conference table; the last relic of corporate productivity, Byju is turning on the charm.
