Fangfang Wu is the CEO of Greenbox, a children's clothier based in Shanghai. Launched in 2003, Greenbox is now the No. 1 children's apparel retailer on Chinese e-commerce giant Taobao. Wu, a former marketing exec, started the company a few years after she and her husband welcomed their daughter, Alice, into the world. Dismayed by the shoddy, boring clothing she found for sale, Wu, a self-taught designer, created her own.
