This document discusses strategies for identifying and cultivating potential major donors from an organization's existing donor database. It provides tips on focusing stewardship efforts on long-time loyal donors who have given consistently for 3-5+ years, monthly donors, volunteers who haven't yet donated, out-of-town donors, current/former service recipients, and others who show signals of higher capacity or engagement with the organization. The key message is that the best prospects are often hidden in plain sight in an organization's existing donor data, rather than relying solely on wealthy strangers.
