Our methodology

Grantsbase is only useful if the data is accurate and current. Here's how we collect and maintain it.

Sources

We pull from official, authoritative sources only: Grants.gov, federal agency funding portals, the Federal Register, state grant portals, and published foundation listings. We don't scrape unverified aggregators.

Collection

Automated crawlers run on a daily cadence. Each opportunity is parsed into structured fields — funder, amount range, deadline, eligibility, location and industry — so it can be filtered precisely on search.

De-duplication

The same opportunity often appears in multiple places. We compute a content hash from the title, agency, deadline and amount, and keep a single canonical record per opportunity.

Freshness

Closed opportunities are removed automatically; new ones are added as they're posted. See how we verify each listing.
