*Signed Bookplate by Rajiv Shah Rajiv J. Shah, president of the Rockefeller Foundation and former administrator of President Barack Obama’s United States Agency for International Development, shares a dynamic new model for creating large scale change, inspired by his own involvements with some of the largest humanitarian projects of our time. Rajiv J. Shah is no stranger to pulling off the impossible, from helping vaccinate 900 million children at the Bill & Melinda Gates Foundation to a high-pressure race against the clock to stop the spread of Ebola. His secret? A big bets philosophy—the idea that seeking to solve problems rather than make incremental improvements can attract the unlikely partners with the power and know-how to achieve transformational change. Part career sweeping memoir, part inspirational playbook, Big Bets offers a master class in decision-making, leadership, and changing the world one bet at a time.
