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 homelessness, 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 most ambitious and effective public-private philanthropic partnerships ever, with topics including conservation in the Brazilian Amazon, health services in nine West African countries, and food security in New York City. Ivan has also 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 equator three times.
