Candid (formerly GuideStar)

A nonprofit ourselves, we are champions of transparency who believe information is key to driving change in our communities. We offer the highest-quality data on 1.9 million nonprofits in the United States, but we know it can be daunting to find the information that matters. That’s why we don’t just rely on IRS data; we clean the data, make it discoverable, enrich it with data collected directly from organizations, and deliver it in a way that makes it easy to explore and understand.
