Asks You Can Count On
You no longer need to shoot from the hip when deciding how much to ask a donor for a major gift. Donor Abacus™ makes sense of and operationalizes donor research. Abacus uses bias-free data about a donor and their relationship to your organization to arrive at a bold yet respectful 3-year Pledge Ask and highly predictive pledge Goal – so you can Ask with confidence and maximize pledges. Your donor pipeline and portfolio valuation and prioritization will also be more accurate, predictive, and useful for planning.
