The GrantAdvisor.org web service was just launched in California and Minnesota, and will be spreading to other locations:

GrantAdvisor is a web service that facilitates open dialogue between nonprofits and grantmakers by collecting authentic, real-time reviews and comments on grantseekers’ experiences working with funders to encourage more productive philanthropy.

Feedback is shared anonymously and once a funder receives 5 reviews, the data on that funder will be posted publicly and funders will have the opportunity to respond to reviews.

In addition to aggregating feedback on the grant application process, GrantAdvisor will provide a forum to share views on how funders influence their field. This allows funders to understand how they are perceived as leaders and influencers, not simply as grantmakers, and (not that the analogy isn’t obvious enough):

If you’re going on a trip, you check TripAdvisor; if you’re going to apply for a grant, you check GrantAdvisor! If you’re a hotel, you check TripAdvisor to learn valuable customer feedback you can’t get any other way!
