Byju's went from being a oneman coaching centre to being an education technology pioneer with millions downloading its learning app and signing up for its courses. Its innovative marketing strategy, built around the 'Fear of Missing Out', made it into a household name. It built a huge brand and went global, claiming a dizzying valuation of $22 billion. But today, saddled with governance, ethical and financial issues, Byju's is symbolic of all that is wrong with the edtech industry.
