Windfall aggregates information from third-party data sources and builds additional models on top of that data. Windfall is one of the more modern traditional wealth screening tools, but it still suffers from the same black-box problem as its peers: Windfall doesn't cite its sources or show full profiles (no complete philanthropic giving histories; no net worth explanations; etc).
WealthAtlas, on the other hand, is built from the ground up with AI; our agents research prospects across the entire open web (+ proprietary databases), put together fully verified profiles, and cite every source so you can see exactly where a given piece of information came from.
Teams switch from Windfall to WealthAtlas so that they have more accurate, more up-to-date, and more useful profiles — with every fact cited back to its source. That means less time aggregating data and more time engaging the right people.
