DonorSearch: Innovation Since Day One

DonorSearch was founded in 2007 with one goal: to provide more accurate, more comprehensive, more actionable data to help nonprofits of all types achieve better fundraising and outreach results.

Headed by industry veterans, DonorSearch is a leading provider of prospect research to nonprofits of all types, including charities, healthcare organizations, fraternities/sororities, religious organizations and educators.

Using information from 25 databases, DonorSearch uses proprietary algorithms to help clients find the best philanthropic prospects. DonorSearch’s data can be easily integrated with most common donor management and general sales software, putting critical donor information at a client’s fingertips.

DonorSearch is the only prospect research company that:

  • Searches and analyzes wealth and philanthropy databases

  • Reviews key information manually for greater accuracy before you receive it

  • Can predict both capacity and propensity to give with confidence

  • Provides in-depth information to help development personnel formulate approach and ask strategies

  • Helps development offices allocate scarce resources most efficiently
