Frequently asked questions
What are the largest diseases, disorders & medical disciplines foundations?
By grants reported on their latest 990s, the largest are American Heart Association Inc ($198.2M across 833 grants), Cystic Fibrosis Foundation ($189.6M) and Breakthrough T1D ($79.3M). Together the top 10 account for 76% of the $905.2M given by the 190 grantmakers focused on diseases, disorders & medical disciplines that made at least 5 grants. Organizations that reported large giving in fewer grants, usually a single transfer to an affiliated charity, are left out of the ranking.
How big is a typical grant from these funders?
The typical grant is about $34K (the median of each grantmaker's average grant). Half of these grantmakers gave less than $81K in total in their latest filing year, so many are small foundations that give to a few organizations they already know. The largest funders make many more grants, but also get the most requests.
Where are these funders based?
Most are in California (75), New York (73) and Florida (54). Many foundations only fund near where they are based, so check each funder's giving geography before you apply.
How do I find which of these funders accept unsolicited proposals?
Most private foundations don't run an open application. Their 990-PF says whether they only give to preselected charities, and their past grants show who they actually fund. Start with the funders above whose grant counts and typical grant size fit your budget, then check each profile's grant history for organizations like yours before you reach out. Read the grant prospecting guide.
