Onion Academy

elsewhere's corpus doesn't carry material under the name "Onion Academy" — what it does cover is the Chinese K-12 edtech company 洋葱数学 (Onion Math), which is likely the same outfit under its earlier name. Per a 峰瑞资本 (FreeS Fund) deal announcement, it was founded at the end of 2013, growing out of a rural education-informatization nonprofit project, by three co-founders: Harvard graduate Linfeng Yang, Duke graduate Ruochen Zhu, and former Innovusion Works "Dianxin OS" tech executive Li Nuo . Yang and Zhu had earlier co-founded the nonprofit "Sunshine Library" in 2011 , and Yang serves as co-founder & CEO .

The company focuses on internet-based inclusive education for primary and middle school students, built on 100% human-machine interactive learning and adaptive video courseware . FreeS Fund was an early backer — Li Feng led the investment — and per FreeS's own writing, its user growth was largely organic through word of mouth, going from 0 to 10 million users with acquisition costs well below industry norms . By April 2019 it had closed a 300 million yuan Series D, with FreeS continuing to follow on . As for the "Onion Academy" rebranding and the company's more recent state, elsewhere's corpus does not cover that.
