Bridgespan at UNGA and New York Climate Week 2026

This September, Bridgespan leaders will gather in New York alongside the UN General Assembly (UNGA) and Climate Week NYC—joining critical conversations, participating in events, and hosting convenings of our own. We will be connecting with leaders across philanthropy and the social sector to exchange ideas and help advance solutions to some of today’s most consequential challenges, with conversations spanning AI and the future of the social sector; climate and health; community-driven change; gender equity; big-bet philanthropy; the role of private capital in catalyzing change at scale, and more.

If you’ll be in New York, we’d welcome the opportunity to connect.


Meet the Bridgespan Team at UNGA and Climate Week NYC 2026
