When Hurricane Katrina hit, the founder of GreatNonprofits, Perla Ni was the publisher of the Stanford Social Innovation Review (www.ssireview.org).  She was asked by corporations and individuals who to donate to in places impacted, such as Biloxi, Mississippi

"I learned about several excellent, local nonprofits through one of our journalists who went to Biloxi. He asked people which nonprofits had been there to help them. He learned about a couple of small nonprofits who were distributing water and helping people living in their cars.   

It was clear that donors and prospective volunteers needed this kind of on-the-ground view from the community. We needed an online "Tripadvisor for Nonprofits” - to give a voice to the experiences of clients of nonprofits, volunteers, and involved donors.  And to help prospective donors and supporters find great nonprofits."

Since its founding in 2007, GreatNonprofits has quickly grown into the leading provider of reviews and ratings of nonprofit organizations throughout the U.S. Our review methodology takes into account the diversity of the nonprofit sector -- we host reviews of groups of all different shapes and sizes and types from the smallest grassroots groups operating on the local level, to the large regional, national, and international organizations.
