As a side note, the Shin in the article is a family member of the “big brother” Chaebol, Samsung Group, which has close knots with big conglomerates such as CJ Group, Joongang Ilbo, Shinsegae, and more, almost to the extent of their aggregate revenue reaching almost a half of South Korea GDP, so he earned attractive deals from big local brands so easily. Shin wan’t irrational enough not to exploit his family connections to build a business based on a totally unprofitable model, a feat only possible at the right moment and right place. Definitely, he’s a smart guy, smart enough being ready to return if he no longer sees his advantages here in Seoul, which I think would be quite unlikely though, due to his superb “Zuck status” in S. Korea.
