Portfolio insights
Your whole portfolio on one page.
Plinth reads the reports and notes already in your grants system and shows what keeps coming up across the organizations you fund. Nothing new is asked of your grantees.
Free, with no account: every US grantmaker’s giving, read from their own IRS filings.

Four questions Plinth answers from the reports you already collect.
“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.
“Who haven't we heard from?”
Overdue reports and grantees who have gone quiet, with the site visits and renewal decisions coming up.
“Where does our funding land, and where doesn't it?”
Grantmaking by cause over several years, how concentrated funding is among your largest grantees, and organizations in the area you do not fund yet.
“Who needs attention now?”
Every grantee seen by how much is at stake and how much concern there is, next to the open requests they have made.

Sits on top of the system you already use
How Plinth connectsBlackbaud, Fluxx, Foundant, Salesforce, and your spreadsheets. Plinth connects to your system, so there is nothing to migrate.
Grants management system
Or run your whole grants process on Plinth.
If you would rather replace your current system, Plinth is a complete grants management system too.
Due diligence checks, run automatically
Every applicant screened as the application arrives: 501(c)(3) status, OFAC and other watchlist name screening, Form 990 analysis, and financial health against your own criteria. Each result links to the record it came from, for your team to review.
Funding across borders
Name screening against sanctions and terrorism-related entity lists, plus foreign entity checks, collected in one place for cross-border grants.
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 211,000 US grantmakers and 19.8 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, screen compliance, and pull grants data through an API with a familiar parameter vocabulary and a migration guide from Candid. 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.

What Plinth won't 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.
