“What's building across your grantees?”
Signals that keep recurring across reports, grouped by what they are about. Scattered updates become a small number of named patterns.

Our Grants Management System
Power your entire process.
Plinth also functions as a fully-functional system for your entire grants process.
- Due diligence that runs itself. Every applicant checked automatically: 501(c)(3) status, OFAC and watchlist screening, Form 990 analysis, and financial health against your own criteria. Every source linked, every check logged, a complete record behind every decision.
- Funding across borders. The checks and documentation that make international grants defensible, including sanctions and anti-terrorism screening and foreign entity checks.
- Applications you can build yourself. Your own forms, edited whenever you need, without a developer.
- Eligibility screening built in. Applicants see straight away whether they qualify, so nobody wastes anybody's time.
- Assessments that fit your process. As many review stages as you need, each with its own set of questions, so the real work doesn't end up in spreadsheets.
Free and public
We also publish the US funding graph.
Plinth Data is a US nonprofit and foundation intelligence database built from public IRS Form 990 and 990-PF filings — about 205,000 grantmaking foundations and 17.9 million grants, resolved into a multi-year funding network. Research who funds any nonprofit, explore every foundation’s grantees, identify co-funders and similar portfolios, and pull grants data through an API. Free to browse, no account.
It is the outside view of a portfolio. Plinth’s funding portfolio intelligence joins it to the inside view — live data from your own current grantees — so both sit in one place.
One company, three sites. Plinth is a funding portfolio intelligence, philanthropy data and grants management platform for foundations and nonprofits, operating in the United States and the United Kingdom. This site, useplinth.com, is our US product site; data.useplinth.com is our searchable US philanthropy database, built from public IRS Form 990 and 990-PF filings; and Plinth UK — grants management and impact reporting for UK funders and charities is our United Kingdom operation.
Sorry we're not sorry.
What we'll refuse to do.
Plinth doesn't rank or rate the organizations you fund.
Public records add context around an organization, but they never stand in as a verdict on one. A better documented nonprofit shouldn't come out ahead of a smaller one doing better work.
Your definitions, not ours.
Your own definitions of impact and financial health, and you can change them whenever you want.
Your officers' own words.
Your program officers' own words are always available, so you can show what a person actually wrote rather than a summary.
Your data stays yours.
It is never used to train AI models.
See it on your own portfolio.
Bring one focus area and a year of reports. We will show you what is in there.
