Facebook’s Chief Revenue Officer David Fischer has decided to part ways with the social network. Fischer, among the highest-ranking official under COO Sheryl Sandberg, is responsible for advertising and marketing efforts for business products. He was also involved in some of the large deals, including a $5.7 bn investment in Jio Platforms. Fischer joined FB in 2010 after working alongside Sandberg at Google. Both of them have worked together at the USA Treasury Department, as well.
