Strong fundraising pipelines are built long before a proposal is written. This session explores how advancement services, alumni engagement, communications, fundraising, and related teams can work together to build a healthier long-term donor pipeline across the institution. Using examples grounded in behavioral science and prospect development, attendees will examine how engagement signals help identify future donors, how organizations move constituents from engagement to philanthropy over time, and how advancement services professionals can support sustainable donor growth beyond short-term fundraising outcomes. Participants will leave with practical ideas for thinking more collaboratively, strategically, and institutionally about pipeline development.
