Windfall helps me create an action plan with each donor.

What I find most helpful is that the information Windfall provides is truly actionable. Their research gives me real, concrete insight into a donor, which helps me decide how best to engage with them and steward the relationship. Net wealth is useful, but on its own, it doesn’t tell me what a donor’s passions are—such as the other nonprofits, charities, and political activities they support. Since we have a lobbyist and several programs that address different areas, like science education and evidence-based medicine, it’s valuable to know whether a donor is interested in politics, social policy, education, medical research, or secular humanism.

Transforms Donor Engagement with Rich Details and Easy Integration

I like using Windfall because it is an effective wealth screening tool that integrates well with our CRM. I appreciate the level of detail it provides about high-net-worth individuals, which allows us to personalize our outreach efforts better. I also find it valuable to see properties owned, recent familial happenings, life events, and areas of philanthropic interest, as this helps us paint a richer portrait of our donor database to see them as real people. Additionally, the initial setup of Windfall was easy, and their customer service is great.
