DonorSearch vs. Windfall: Why DonorSearch Is the Best Choice
Nonprofits of all shapes and sizes choose DonorSearch by EverTrue over competitors like Windfall for DonorSearch’s tailored customer service, comprehensive insights, and ease of use.
Why Nonprofits Choose DonorSearch Over Windfall
Tailor-Made for Nonprofits
Windfall caters to many audiences across various nonprofit and for-profit verticals, so its platform is built for customer research as well as donor prospecting. Meanwhile, DonorSearch only serves fundraising organizations, and our platform is designed specifically for surfacing and analyzing donor insights. DonorSearch was built for philanthropy, so we understand your unique fundraising needs and can provide the exact tools you need to succeed!
Comprehensive Prospect Research
Windfall primarily focuses on wealth screening, meaning it surfaces thorough insights into potential donors’ ability to give but gives very few details about their willingness to support your nonprofit. DonorSearch, however, is a wealth and philanthropic screening solution, so it goes further to surface prospects’ giving histories and affinity for your mission as well as capacity data. This way, you get a full picture of each donor and can cultivate stronger relationships with the individuals you’re confident are the best fit for your nonprofit.
Cutting-Edge, Responsible AI
Windfall only offers a predictive AI tool, which again relies primarily on wealth data and isn’t nonprofit-specific. DonorSearch’s AI tool offerings are much more comprehensive—drawing from a more balanced set of wealth and philanthropic data, customizing models to your needs, and leveraging both generative and predictive AI. More than that, DonorSearch has been at the forefront of machine learning in the nonprofit sector for several years and is committed to promoting responsible AI usage as a member of Fundraising.AI.
Top-of-the-Line Platform Integrations
DonorSearch integrates with more than 40 nonprofit fundraising tools and constituent relationship management (CRM) systems. This number is the most of any prospect research solution on the market—including Windfall, which has fewer than 30 software integrations, many of which aren’t nonprofit-specific. Platforms that DonorSearch integrates with and Windfall doesn’t include Blackbaud Raiser’s Edge NXT, Blackbaud CRM, Tessitura, Little Green Light, and the rest of the EverTrue suite of donor management tools.

What came back was that DonorSearch had the most accurate results. We picked people that we knew so that we could really validate those [results].…And the accuracy…made choosing DonorSearch pretty much a no-brainer.”
