Methodology & Data Sources
Where the grant and funder data on grantedai.com comes from, how often it refreshes, and how we keep it honest.
What we aggregate
Granted pairs AI with public funding data to help nonprofits, researchers, and small businesses find opportunities they're eligible for and understand who funds their work. Every source below is public and official; every opportunity we publish links back to the funder's own posting, which stays the authority on its own program. Search is free.
Data sources
Each source below lists what it provides and how often we refresh it. Live opportunity feeds are polled by an ingestion runner that checks for due sources several times a day; large historical datasets are loaded from published bulk archives on a periodic basis.
Grants.gov
Three times a week (Mon / Wed / Fri)Federal grant opportunities with full descriptions, award amounts, and eligibility requirements — the backbone of our live listings.
Federal Register
Checked about twice a dayAgency notices of funding availability (NOFOs) published in the daily Federal Register.
SAM.gov assistance listings
Checked about twice a dayFederal assistance program listings (formerly CFDA) that describe what each program funds and who is eligible.
NSF, state portals & international funders
Polled on a rolling cycle through the dayMore than 100 additional live opportunity feeds — NSF programs, state grant portals (California, New York, Florida, and others), and international funders.
SBIR / STTR (SBIR.gov)
Polled on the same rolling ingestion cycleSmall Business Innovation Research and Technology Transfer solicitations across participating federal agencies.
USAspending.gov federal awards
Loaded periodically from published USAspending bulk archives7M+ historical federal award records — past grantees, award amounts, and funding agencies — used to show who has won what.
IRS Form 990 filings
Loaded periodically as new filings are releasedFinancial and grantmaking profiles for 133,000+ foundations, including assets, giving, and reported grants.
How listings are verified
Opportunities don't just get ingested and forgotten. Automated jobs re-check listings against their official sources on a rolling basis: a daily verification pass confirms live grants against the funder's posting, a separate re-verification drip revisits previously accepted opportunities, and a nightly staleness sweep marks grants whose deadlines have passed as closed so expired opportunities don't linger. Broken links are detected and repaired, and the health of every source feed is monitored so a silent upstream failure gets caught rather than quietly aging the data. Deadlines, amounts, and eligibility are drawn from the cited primary source, never invented.
Known limitations
- IRS 990 filings lag. Foundation financials come from Form 990 filings, which the IRS releases on roughly a one-to-two-year delay. A foundation's most recent giving may not yet be reflected.
- Federal awards are as-published. Our 7M+ award records reflect USAspending.gov as reported by agencies; we mirror that data and don't independently restate it.
- AI-assisted processing can err. We use AI to summarize and structure funding data, and it occasionally gets a detail wrong. When a source and our listing disagree, the source wins — and we want to hear about it. Corrections are welcome at team@grantedai.com.
