In December 2016, Fortune and our then-sister publication, Time, took 100 CEOs from the world’s largest companies to Rome, to deliberate on things the private sector could do to address global social problems. The event culminated in an inspiring meeting with Pope Francis in the Clementine Hall of the Vatican. It turned out to be a seminal moment, not only for Fortune, but for the development of stakeholder capitalism. Many of the companies participating have since doubled down on their commitment to a capitalism that better serves society.
