For nonprofits · The Funding Hub
Search the money that funds missions.
The Funding Hub is 501 Labs' funding database: federal grants, federal assistance programs, private foundations, and community foundations, collected into one searchable place. Free, no account. Results here are live.
Try a cause and a place: food security in Monroe County, youth mentoring, rural broadband.
01What is inside
Public sources, collected and kept current.
Most sources refresh nightly; foundation filings update as the IRS releases them. No paywall and no per-seat pricing.
- Federal grant opportunities from grants.gov, NIH, NSF, and the Federal Register
- Federal assistance programs (CFDA listings) from SAM.gov
- Private foundations from IRS 990 filings: who they fund, where, and how much
- Community foundations, indexed by state and metro
- State grant portals for California, New York, Texas, Illinois, Maryland, Connecticut, Vermont, Oregon, and New Jersey
02 · Matching
Ranked against your mission, not just keywords.
Seek, the grants Block, matches the Hub against your organization's mission profile and ranks what comes back: opportunities you can add to a pipeline, plus the foundations, federal programs, and community foundations most likely to fund work like yours. Free in Blocks.
03 · API and MCP
For developers and AI assistants.
The Hub is also a service: a REST API for verified nonprofits and an MCP connector so assistants like Claude can search it directly. Keys are issued from a free 501 Labs account under Seek.
Why is this on a consultant's website? Our founder started 501 Labs and built the Hub. Civic Dialog clients who serve nonprofits use it during scoping to size the funding a build could unlock. Everyone else should simply use it.
