Great Support, better targeting and stronger insights into our system.

Provides a different way of looking at the data and gives us better insights into who we should be working on targeting in our strategies. Easy User interface which integrates well with our systems, along with the support which we get makes the process easy to implement.

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.
