You've been here before
You're not supposed to need a library card to research your own funders. And yet.
- You spend an hour searching for funders and end up with a list you don't trust
- You hit a paywall just to filter by state or revenue on data the IRS publishes for free
- You need to export 200 rows and get told to "contact sales"
- Grant data is split across IRS filings and government databases with no way to search it together
- The data you finally find is two years old, and you have no idea when it was last updated

The sector has been saying this for years
These aren't our words. They're from researchers, regulators, and the people who actually use nonprofit data every day.
The sector needs data files that are already structured for use in familiar software, easily searchable, and readily available.

Without those Form 990s, you can't have an efficient market.

Subscribing to multiple prospecting tools or resources can quickly become costly, especially for small shops.

The entire sector is affected... but nonprofits end up carrying the heaviest burden because it directly affects their ability to fundraise effectively.

FAQ
Where does the data come from?
IRS Form 990 e-file data (normalized across 20+ schema versions and all three form types) plus federal award data from the Federal Audit Clearinghouse (FAC). Two public data sources, one unified search.
How fresh is the data?
Updated monthly from IRS releases. The IRS publishes new e-filed returns on a rolling basis, typically with a 6-12 month lag from the filing date.
What's included in the grant data?
Foundation grants from public charities (990 Schedule I) and private foundations (990-PF Part XV), plus federal award data from the Federal Audit Clearinghouse. 16 million+ grants searchable in one place. Filter by funder, recipient, amount, state, year, and source.
Does it include associations and other org types, not just charities?
Yes. The database covers all tax-exempt organization types that file electronically: 501(c)(3) charities, 501(c)(4) social welfare organizations, 501(c)(6) business leagues and trade associations, private foundations, and more. If they file a 990, they're in here.
How is this different from other nonprofit data tools?
Most free tools let you look up one org at a time but don't support filtering, export, or bulk access. Most paid tools start at $1,500+/year with annual contracts, charge per-record export fees, or gate API access behind a sales process. 501(see) gives you search, filtering, grant data, officer compensation, and CSV export starting at $0, with paid plans at $49-99/month, no annual lock-in, no per-seat fees, and no per-record fees.
Do I need to be technical to use this?
No. You can search, filter, and export data without writing any code. Developers can also connect via our REST API for automated workflows and integrations.
Are there per-record or per-export fees?
No. Your subscription includes export. No per-record charges, no surprise fees for downloading a CSV. If you can search it, you can export it.
How does the API work?
Subscribe to Pro, generate an API key in settings, and start making requests. No application form, no waiting for approval, no sales call. Full OpenAPI 3.1 spec, semantic field names (total_revenue, not f9_01_rev_tot_cy), and structured JSON responses that work with LLM tool-use and MCP out of the box.
Does the search require exact spelling?
No. Our search handles approximate and misspelled names. Searching "habitat humanity" will still find "Habitat for Humanity International."
Is 501(see) live?
Yes. Sign up for free and start searching immediately. No waitlist, no approval process.
