These two appointments have expanded the Board to eight members, from six previously.

Mr. Xiaoguang Wu, also known as Free, currently serves as the co-founder of Welight Capital and as an advisor at Eleven Two Capital. He was named as senior management adviser of Tencent in June 2015. Mr. Wu joined Tencent (SEHK: 00700) in 1999, and was a member of the founding team. He led the development and product planning for Tencent’s core product, QQ, and served as project manager for the QQ research and development team.
