Wall Street's darling, Google Inc., offered more than a pretty financial picture. Poverty, communicable diseases and climate change - some of the world's largest problems - were also key interests of Google's cofounders. By applying innovation and significant resources, Google's cofounders hoped that their efforts in these areas would one day eclipse Google itself in worldwide impact. On February 22, 2006, Google Inc. announced the appointment of an executive director of the newly created Google.org. With one per cent of Google Inc.'s equity and profit as seed money, Google.org's mandate was to address climate change, global public health, economic development and poverty. Although charity by successful entrepreneurs was not unusual, this press release signaled a new organizational form, a for-profit philanthropic company. The new executive director's task ahead was unprecedented. How could he leverage the company's for-profit status to make the biggest impact possible with the resources trusted to Google.org? What decision-making criteria should be used for strategic investments? How would he measure Google.org's success?
