The net worth ratings do appear to be accurate, for the most part, and attributed to the correct people. It is easy to self-serve lists for screening in the portal. Unlimited runs of data in the contract year is a big plus, so you can run lots of data, in big or small batches, as much as you want. They do provide various wealth markers (Y/N columns for ownership of multiple properties, or exotic cars, etc) in addition to the net worth estimate. It's data that is easily interpretable, and gift officers respond well to the simplicity of what it is -- pure wealth estimate. Customer support is always very responsive, and they are proactive in reaching out to schedule check-ins.

Windfall is a powerful wealth screening tool that provides accurate, real-time data to help identify high-potential donors. Its insights go beyond raw numbers, offering a deeper understanding of wealth capacity. The platform is user-friendly, with an intuitive interface and strong customer support. Windfall remains an essential asset for data-driven fundraising. I highly recommend it to development professionals looking to enhance donor engagement and strategy.
