Over 200 customers use Cause IQ to grow, maintain, and serve their nonprofit clients.
Methodology: Cause IQ mines all tax-exempt organizations that file a Form 990 or 990PF with the IRS. We exclude Form 990EZ and Postcard filers, which are high in number but very small in size. We collect and aggregate this information from OCR'd paper taxreturns, XML e-file taxreturns, IRS-provided extract, the Business Master File, and Cause IQ secret sauce for data cleaning, categorization, classification, analytics, etc.
This category corresponds to the "D50: Zoo, Zoological Society" National Taxonomy of Exempt Entities (NTEE) code. Cause IQ determines NTEEs for organizations by its own internally-developed secret-sauce algorithms.
Cause IQ is a website that helps companies grow, maintain, and serve their nonprofit clients, and helps nonprofits find additional foundation funding. Our data and tools help professionals prospect for nonprofits, research opportunities, benchmark their clients, and enrich existing information.
