Sheryl Sandberg, COO, Facebook

Since her appointment as Chief Operating Officer in 2008, Sheryl Sandberg has had a huge impact on the progress of Facebook – helping the social media giant become more profitable by increasing its focus on discreetly placed advertising. Sandberg is particularly interested in feminist issues, having written Lean In: Women and the Will to Lead in 2013, which received high praise for its pragmatic solutions to gender inequality in the workplace.
It was shortlisted for Business Book of the Year Award by The Financial Times and Goldman Sachs. Sandberg currently
