Ed Grefenstette is the CIO of The Dietrich Foundation, which supports charitable organizations in Western Pennsylvania through a truly unique investment strategy that seeks to first, last, and always grow the assets. Bill Dietrich, a successful industrialist, published historian, international investor, and innovative philanthropist, formed the foundation after selling his business for $170 million in 1997. Since then, the pool has grown 11.5x to $1.5 billion after distributing $400 million to supported charities, including contributions that make it among the largest donors every year to Carnegie Mellon University and the University of Pittsburgh. Over the last twenty years, the Dietrich Foundation's performance sits at the very top of all endowments and foundations.
Our conversation covers Ed's journey to investing and mentorship by Bill Dietrich, which led to him taking the helm at the Foundation in 2007. We discuss the Foundation's bold approach to illiquid investments, with 90% of assets invested in venture capital and private equity, its governance structure, and its thematic focus on innovation and emerging markets. Along the way, Ed shares insights into managing liquidity, constructing the portfolio, selecting managers, and navigating geopolitical risk to maintain conviction in an uncomfortably different strategy.
Ed’s approach and results will open your aperture to what’s possible in an institutional portfolio with the right goals, structure, and governance in place.
