Does this grantmaker accept applications?

Its tax return does not say, and we will not guess. Private foundations file Form 990-PF, which asks outright whether they fund only organizations they select themselves -- 78% say yes, and that one answer is what lets the rest of this site tell you which foundations are worth approaching. Grantmaking charities like this one file a regular Form 990 instead, and the IRS never puts the question to them. Anyone claiming to know the answer from the filing is inventing it.

Three things in the filing do bear on it:

  1. What kind of organization it is. For Proteus Fund Inc, the IRS classifies it under education rather than as a grantmaker (NTEE B99) -- it is an operating charity that also makes grants.
  2. How spread out its giving is. 575 distinct organizations, with 16% of the dollars going to the largest single recipient. That is genuinely spread out -- the mark of a funder making many independent decisions rather than underwriting one institution.
  3. How much its list changes. 44% of one year's grantees are funded again the next, across 3 year-to-year transitions. That is below the 57% median for grantmaking charities, and well below the 67% private foundations manage. A list that turns over this much is one a newcomer can realistically join.

How big are its grants?

The median reported grant is $30,000. Half of what it reported fell between $15,000 and $56,620; the smallest was $5,348 and the largest $7,750,000. If you are asking for materially more than the top of that range, you are asking the wrong organization.

Schedule I only reports grants over $5,000. Form 990 requires a charity to list recipients it paid more than that and lets it omit the rest, so every grant-size figure on this page describes the grants it reported, not all of them. Its real median is lower and its real recipient count is higher. This is also why these numbers cannot be compared with the private-foundation figures elsewhere on this site -- Form 990-PF has no reporting floor, so the two are different populations rather than two samples of one.

Every organization it funded

All 575 recipients appear in its filings; the 250 largest are listed here. Years funded is the number of separate tax years in which the organization received money -- the clearest signal of who this grantmaker actually has a relationship with.

260 of 575 (45%) received money in more than one year over the 4 years we hold. Remember the $5,000 floor: an organization funded every year at $3,000 shows up here as never funded at all.

It also reported 1 group of grants to individuals -- scholarships, emergency assistance and similar. Schedule I reports these by category with a headcount and never by name, so there is nothing here we could publish about the recipients even if we wanted to.

What kind of organizations it funds

By each recipient's own IRS classification, for the 505 of 575 recipients we could match to a registered organization. These are assigned categories, not our guesses -- Schedule I reports the recipient's EIN, so this is a lookup rather than a name match.

Tax years, not calendar years, and the most recent year is usually incomplete -- Form 990 arrives about a year after the year it covers, so a low final year means late paperwork rather than a grantmaker winding down.

Where its money goes

33% of its giving went to organizations in District of Columbia. Community foundations and federated funds are usually the most geographically bounded funders there are -- being outside the footprint is normally disqualifying in a way that a weak programme fit is not.

Funders that support the same organizations

These grantmakers and private foundations gave to organizations this one also funded. Shared grantees are the strongest signal available that two funders have overlapping priorities -- and a funder already backing your peers is a far warmer prospect than one that merely lists your cause.

How to approach this grantmaker

  1. Look for a published programme first. Unlike most private foundations, organizations of this kind often do run open, deadlined grant cycles with written guidelines. Its own website is the authority on that; this page is the authority on who it has actually paid.
  2. Check you are its size. The median reported grant is $30,000 -- and because grants under $5,000 need not be reported, it very likely writes smaller cheques than this page can see.
  3. Check you are in its geography. Its giving concentrates in District of Columbia.
  4. Read the recipient list for organizations like yours. If nothing on it resembles your work, that is a real answer and a cheap one to get.

This is history, not an open call. Form 990 is published about a year after the tax year it covers. Nothing on this page is a deadline. It is a record of who this organization has actually funded, which is the best available predictor of who it will fund next.
