Looking for clues as to whether you picked the right organization to apply to? Find the projects an organization is currently funding. Does your proposal seem like it might be on a topic they have shown a demonstrated interest in?

For mid-size and smaller foundations you can find grantee names and award amounts on their Form 990 (see below). Many government agencies have search tools you can use to locate current and recent grant recipient information.
