Byju’s revised its sales strategy and stopped using a method of operation that had caused the edtech giant problems in the past. The most valued startup in India, based in Bengaluru, declared on Monday that its sales representatives would no longer go door-to-door to pitch to parents of students. Rather, the whole sales crew now operates out of the office and mostly interacts with people whose kids have shown a great interest in utilising the platform. The so-called 4-tier strategy, according to the startup, includes a number of tests to confirm buyers’ intent and agreement to buy a subscription. The child’s household income must be at least 25,000 Indian rupees ($306) in order to proceed with the purchase, according to Byju’s, which also claimed to have instituted an affordability test for all prospective clients.
