Great Inexpensive and Moderately Priced Resources

ProPlatinum is a bundling of data providers including ZoomInfo’s PowerSearch, NOZA’s database of charitable gifts, GuideStar’s Grant Explorer, HEP Development’s database of matching-gift companies, Larkspur Data database of wealthy people, and iWave’s own form 990 search tool. Subscriptions start at $2,595. (Individual subscriptions to these data providers would collectively be much more costly than the ProPlatiNum subscription.)
