BENGALURU: Byju’s shopping spree continues. The Bengaluru-based digital learning firm has done two more big acquisitions. It has bought Singapore-based Great Learning, which specialises in online higher and professional education, for $600 million. And it has bought Toppr, which offers online content for schools and competitive exams, for $150 million. The company has done some 15 acquisitions to date, spending nearly $3 billion. Last week, it acquired US digital reading platform Epic, focused on kids aged 12 and under, for $500 million. Byju’s is building itself into a digital and online learning powerhouse — focused on everything from K12 to competitive test preparation and professional education. The idea is to create a continuum for lifelong learners. Byju’s said it has earmarked a further $400 million towards accelerating Great Learning’s growth.
