Social Finance Inc, otherwise known as Sofi, is still a relatively young company having first come to fruition in 2011. The personal finance and loan business has welcomed many investors since then, including Beijing-based company Renren among others.

As one of the earliest investors in the company, Renren holds a large stake SoFi. It sold off some of these shares in 2017 to gather funding for future developments, but according to Crowd Fund Insider, kept 85.9% of its previous holdings in the company. At the time, SoFi was valued at an incredible price of $14 billion.
