Chinese used car trading platform Youxin has reportedly secured US$170 million of Series C funding from Baidu, KKR and Coatue, just six months after receiving a whopping US$260 million B round led by Warburg Pincus and Tiger Fund. Founded in 2011 by Dai Kun, former VP of car trading platform Yiche, Youxin’s core business brand Youxinpai is a B2B second-hand car auction service platform integrating auctions, vehicle detection, secure payment, logistics and transport for automobile manufacturers, second-hand car agencies and large companies. The new funding will be used to develop Youxin’s B2C used car trading platform Youxin Second-hand Car which launches this week. Until recently, B2B platforms comprised the majority of car trading services due to the prolonged and complicated nature of transactions. Moreover, Baidu is reportedly pushing the rumored merger between Uber and Chinese car rental service provider Yongche.
