Nonprofit financial data is public record. It shouldn't require a sales process to access, a contract to keep, or a data engineering team to make sense of. Just the data you need — with transparent pricing and no gatekeeping.
Free tier included. No credit card required.
IRS 990 data is public. But the tools built around it weren't built for you.
Everything in a 990 filing, organized and searchable.
Find organizations, officers, and grant recipients by name — even approximate or misspelled names. Filter by state, revenue, NTEE code, and more.
See who funded whom, how much, and where. Search grants from both public charities and private foundations in one place.
Revenue, expenses, assets, and liabilities tracked across every filing year. Compare current and prior-year numbers to spot trends.
Names, titles, hours worked, salaries, and benefits for every officer, director, and key employee listed on the filing.
Download results as CSV or pull them via the API. No per-record export fees, no paywalled profiles. The data is public — the export should be too.
990, 990-EZ, and 990-PF data normalized into consistent fields. No need to know which form type a nonprofit uses.
Anyone who needs nonprofit data beyond a one-off Google search.
Find every grant a foundation has awarded — by recipient, amount, and geography — without manually reading 990-PFs. Stop driving to the library for access to funder data.
Build targeted lists of nonprofits by revenue, location, and mission area. Export to CSV with no per-record fees — just the flat subscription.
Normalized, multi-year data without parsing XML or stitching together CSV dumps. Search across organizations, officers, and grants in one query.
Get an API key in minutes, not days. Self-serve access, an OpenAPI spec, predictable pagination, and structured responses — no sales call required.
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.

Directly from IRS Form 990 e-file data. We normalize it across 20+ schema versions and all three form types (990, 990-EZ, 990-PF) into a consistent format so you don't have to.
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.
Grants from both public charities (990 Schedule I) and private foundations (990-PF Part XV), searchable in one place. Filter by funder, recipient name, amount, state, and year.
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 $99-149/month, no annual lock-in, and no per-record fees.
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.
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.
Sign up, get an API key, 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.
No. Our search handles approximate and misspelled names. Searching "habitat humanity" will still find "Habitat for Humanity International."
