Nancy Pfund

Fireside chat

Founder and Managing Partner of DBL Partners, a firm built to prove that venture capital can deliver top-tier returns and real social and environmental impact at the same time. She has backed Tesla, SolarCity, NexTracker, SpaceX, Pandora, Chestnut Carbon, and Bellwether Coffee.

She serves on the Board of Trustees of the National Geographic Society and lectures at Harvard, Stanford, and Yale. We'll sit down with her to walk through DBL's most iconic investments and what she took away from each one.

Talk

Co-chair for Energy and Environment at Singularity University, and one of the first to call the exponential price decline of solar — in Scientific American, back in 2011. Before that, thirteen years at Microsoft leading teams on Outlook, Internet Explorer, and Bing.
