Since founding Redstone, Ivan has helped many of the world’s largest foundations as they tackle tough problems. He has worked across the spectrum of social issues, from energy and climate, to education, to the performing arts, with a particular focus on continuously improved strategies that respond to an ever-changing world. In recent years he has helped construct some of the biggest public-private conservation deals ever, covering the Amazon in Brazil, the Great Bear Rainforest in British Columbia, and Costa Rica’s entire protected area system. Recently he has worked with a wide range of research and advocacy institutions to help them as they focus their work where it can have the greatest impact. Ivan has authored articles on increasing philanthropy’s impact, spoken at many conferences, and co-taught a course about large-scale conservation projects at Yale University.


Before founding Redstone, Ivan was a partner at McKinsey & Company, specializing in consumer electronics strategies and serving clients from both the New York and Tokyo offices. Ivan managed a broad portfolio of clients at McKinsey, including Sony, Hewlett-Packard, and IBM. He worked on issues ranging from corporate strategy to organizational effectiveness.

Ivan lives with his wife Rebecca and two dogs in Boulder, Colorado. He’s a marathon runner who has put more than enough miles on his shoes to circumnavigate the planet twice.
