Online education startup Yuanfudao (猿辅导), which targets China’s middle school and high school test takers, announced a $40 million USD boost from Chinese tech giant Tencent on Tuesday. As far as products go, Yuanfudao’s tutoring app is pretty straightforward – it connects students with tutors, who livestream through the app. In China, buke classes are largely attended by students who want to improve their test scores. Due to the competitive and do-or-die nature of China’s exam system – students can only attend schools that they test into – buke classes are a lucrative business. Yuanfudao joins a number of other education startups in Tencent’s investment portfolio, including Enjoy Learning, a private tutor marketplace, and ABC360, an English language learning startup based in Hangzhou.
