I wouldn't include WeChat as an investment in the same way the others are. Tencent developed WeChat (then called Weixin) themselves. Also, the interesting about WeChat and its difference between the others you mentioned is it functions more as a platform for mobile games and mobile commerce. Tango, Viber (which finally got stickers a few months ago), and Whatsapp are all exclusively about communication. No doubt all of them have looked at folks like WeChat (from China), Line (from Japan), Zalo (from Vietnam) and KakaoTalk (from South Korea) for profitable business models. All of the Asian chat apps are headed in that direction.
