Find Funders
Find the private foundations that have actually funded a cause, from their own IRS 990 filings. Optionally narrow to a US state (that filters by where the RECIPIENT is, not where the funder is). Returns funders ranked by dollars granted.
Open Federal Opportunities
Open federal funding opportunities that are eligible for nonprofit applicants, matched against full synopsis text. Omit the cause to list everything open. A zero result is a measured zero, not a missing feature.
Funding Gap
For each cause: how many open, nonprofit-eligible FEDERAL opportunities exist right now versus how much PRIVATE foundation money demonstrably flowed to it. The gap is the point: several causes have zero open federal doors and hundreds of millions in private grants.
List Causes
