The Best Advice From Fortune Global Forum 2015

November 13, 2015, 1:00 PM UTC

If you bring together founders of the digital companies that are reshaping the world economy and the corporate aristocracy that has dominated commerce for decades, will they have anything to talk about? Turns out they’re ravenous to learn from one another, as we discovered at the recent Fortune Global Forum in San Francisco. The established companies must learn to be revolutionary, and the successful disrupters must learn how to keep winning for the long haul.

Leaders of the corporate old guard included J.P. Morgan Chase’s Jamie Dimon (JPM), Siemens’s Joe Kaeser, IBM’s Ginni Rometty (IBM), Wells Fargo’s John Stumpf (WFC), and many others. Among the Silicon Valley stars were Alphabet CEO Larry Page (GOOG), venture capitalist Marc Andreessen, Airbnb CEO Brian Chesky, and Yahoo chief Marissa Mayer (YHOO).

One powerful lesson that emerged is that even in the age of digital disruption, human capital is the most critical asset—and the most difficult to manage well—for all the leaders. The forum’s agenda is at, and you can watch sessions at the Fortune magazine YouTube channel.
