Grantoria is built to be transparent about where its data comes from and how it is kept current.
Our sources
- Federal grants — Grants.gov, the official U.S. federal grant opportunity system.
- Federal assistance programs — the SAM.gov Assistance Listings catalog (formerly the CFDA).
- State grants — official state grant portals, including the California Grants Portal, Illinois GATA/CSFA, the Ohio Grants Partnership, New York’s SFS Grant Opportunity Portal, Pennsylvania (CODE PA), and the WebGrants systems used by Montana, Iowa, North Dakota, Virginia and others.
- Funding track record — historical award data from USAspending.gov, matched by assistance listing number.
How often we update
Automated pipelines refresh each source on a daily schedule. New opportunities are added, changed listings are updated, and programs that close are marked as closed. Every grant page displays a “Last verified” date so you know how fresh the information is.
AI-assisted summaries
Official grant notices are often long and dense. To make them easier to read, we use AI to generate plain-English summaries — eligibility, difficulty, application tips, and topic tags. These summaries are derived only from the official source material and are supplementary; the official notice always governs. See our disclaimer.
Corrections welcome
Accuracy matters to us. If something looks wrong, please report an issue — we review every submission.
