How to vet a foundation before you apply
Vetting a foundation before you apply takes about 20 minutes and saves a week of wasted writing. Check four things in order: do they accept unsolicited proposals, do they fund your issue and geography, what do they actually give (the 990, not the website), and can you find a warm connection. Most funders should fail the check.
The 20-minute check, in order
Run the checks in sequence and stop the moment a funder fails one. The cheapest disqualifiers come first.
1. Do they accept unsolicited proposals? Many foundations fund only invited or existing grantees, and the website or 990 usually says so. No amount of proposal quality overcomes invitation-only. A closed door is not a dead funder; it moves to the relationship track instead of the proposal track.
2. Do they fund your issue and your geography? Most foundations restrict giving to specific fields and regions. Instrumentl filters both at once, and its 14-day free trial is enough time to vet a season’s worth of prospects (our Instrumentl review covers the full feature set). Grants.gov covers the federal side. Rule out anyone outside your lane before reading a word of program language; geography kills more applications than quality does.
3. What do they actually fund? Open the 990: free on ProPublica’s Nonprofit Explorer, or in more depth through Candid’s Foundation Directory, free on-site at hundreds of partner libraries. Check three things against your ask.
- Grant sizes. If their checks cluster at $10-25k and you need $100k, that is a cultivation-stage funder, not a lead-gift prospect.
- Grantee types. Check whether the grantees look like your organization or like hospitals and universities with familiar names. Some funders’ education giving goes entirely to institutions with endowments.
- Recency and pattern. Three years of filings, minimum. A three-year pattern is a real priority; one year proves nothing. When the giving contradicts the website’s stated priorities, believe the 990.
4. Can you find a connection? A board member, a shared funder, a peer organization they already support. Warm beats cold by a wide margin in foundation giving. Check your board list against their trustee list before every approach; it takes two minutes and occasionally it is gold.
Turn the check into a scorecard
The value is the discipline: 20 minutes to decide whether to spend a week. Keep four columns: accepts proposals, fits issue and geography, giving range matches, connection. Only funders passing all four earn a proposal. Funders passing three get logged with a note on what is missing. Everyone else gets dropped without guilt.
Revisit the three-of-four funders quarterly. Boards turn over, programs launch, and a connection you lacked in March can surface by September. The logged notes make the second look a five-minute job instead of a fresh 20 minutes.
Done consistently, this is the difference between a grant program that chases and one that wins: not better writing, just declining to write for funders whose own filings said no.

Common questions
How long should vetting a foundation take?
About 20 minutes per funder once you have a routine. The point is to spend 20 minutes deciding whether to spend a week. Most funders should fail the check and never get a proposal.
What's the single biggest red flag?
A foundation that doesn't accept unsolicited proposals. Many don't, and no proposal quality overcomes 'by invitation only.' Confirm they take applications before anything else.
Do I need paid software to vet funders?
No. ProPublica's Nonprofit Explorer (free 990s), Grants.gov, and free Foundation Directory access at a Candid partner library cover the whole check. Paid tools save time once your volume grows.
