Ex-Google Guy Builds English Teaching App That Adapts to Student

Yi Wang was hearing the same refrain over and over: Why are English classes in China so expensive? The former Google product manager decided to do something about it and started an app called LiuLiShuo, which basically means "speaking fluently" in Mandarin. The app, which claims more than 30 million users, is one of scores of English-learning startups looking to disrupt China's hidebound language schools. To differentiate itself from products started by Internet giants like Baidu and Tencent, LiuLiShuo brings gaming and social media features to the genre. Users win points when they move to the next level and text each other encouragement and tips.
