Nonprofit Consulting Firms 2026: What The 990s Show

The criterion, written before we looked

An organization appears below only if it meets all three of these conditions.

1. It is a US exempt organization whose IRS Form 990 extract is public and we opened it. A summary of the filing does not count, and neither does a directory entry about it.
2. It sells advice, analysis or strategic support to social-sector organizations, foundations or public bodies.
3. Its extract carries a program service revenue line separate from contributions, which is what makes the share of its work that is actually sold measurable.

Three things are excluded by that criterion and the exclusions matter more than the inclusions.

The pro bono arms of commercial consultancies file nothing comparable, because their revenue is not separable inside a firm that does not publish revenue at all. Any social-sector consultancy organized as a company files no 990 either, so it cannot appear no matter how large it is. And foundations that fund without selling are out by condition two.

So the list below does not tell you who the biggest players in the sector are. It tells you who the measurable ones are, which is a different question, and the only one that can be answered without guessing.

Nine nonprofit consulting organizations, and what each filed

All figures are for the fiscal year ending in 2023, which is the most recent year the extract service returns for eight of the nine. Fee share is program service revenue divided by total revenue, computed by hand for this page.

Two of those rows do the most work. Bridgespan reports $84,763,020 in revenue and MDRC reports $83,947,862, a difference of under a million dollars on eighty-four. Their fee shares are 83.7 percent and 1.1 percent. Dividing the first by the second gives 73.55, so about a 74-fold spread, and that spread measures business model rather than size. Calling one of the two larger than the other would be wrong. Saying that one sells and the other is funded is what the filings show.

The list is ordered by fee share for one reason: it is the only column that says what an organization does rather than how big it is. Order it by revenue and a fund conduit that sells almost nothing leads a list of consultancies.

Seven deficits out of nine, and one broken pattern

The second figure every filing carries is expenses. Subtracting revenue from expenses for the same year produces a result that surprised us.

Seven deficits and two surpluses. Seven plus two is nine.

A tempting story sits in the right-hand column and we are not going to tell it. Both surpluses belong to heavily granted organizations, at 61.7 and 93.2 percent. But MDRC takes 95.1 percent of its revenue as grants and finished in deficit, and so did Rockefeller Philanthropy Advisors at 94.7 percent. Three of the four most granted organizations in the list ran deficits, so the pattern the first two rows suggest does not hold. We publish the observation and refuse the causal claim, because we have not measured a cause.

One caution belongs here and it protects the reader from misreading the whole table. A deficit at an exempt organization is not a commercial loss. An organization can receive a multi-year grant in one year and spend it across the next three, which produces a deficit on paper with nothing wrong underneath. That is one likely reading of several rows above. What the column does establish is that the budget these organizations spend against is set before the year starts and does not roll, which is the economic fact that separates the sector from commercial consulting.

Two organizations losing half their revenue in two years

The filings also carry prior years, and two of the nine show falls that a candidate should know about before choosing where to apply.

Third Sector Capital Partners reported $27,551,770 in fiscal 2021, $8,702,199 in 2022 and $6,113,325 in 2023. Dividing the last by the first gives 0.2219, so 22.2 percent of the 2021 figure remains, a fall of 77.8 percent across two years.

FSG reported $30,240,317, then $21,649,064, then $15,348,424. Dividing gives 0.5075, so 50.8 percent remains and 49.2 percent is gone, across three consecutive declines.

Social Finance moved differently and the direction inside the move is the interesting part. Revenue fell from $73,403,817 to $39,216,945, which is 53.4 percent remaining. Contributions fell by $41,477,488 over the same period while total revenue fell by $34,186,872, and the reason the first number is larger than the second is that fee income rose by $3,469,400. So that organization sold more while receiving much less. The two lines together account for $38,008,088 of a $34,186,872 change, and the remaining $3,821,216 sits in revenue lines the extract does not break out, which is why we do not claim the two lines explain the whole move.

At the other end, the Center for Effective Philanthropy reported $13,719,145 and then $13,668,584, a change of under half a percent. Two exempt organizations in the same list, one holding steady and one down 78 percent over two years.

Two years is not a trend and we do not extrapolate from it. What it establishes is that revenue in this sector moves in ways a commercial consultancy's does not, because a single expiring grant can take a fifth of a year's income with it.

What replaces the profit line in nonprofit consulting work

The economics above are the organization's. The economics inside an engagement are different and they are what a case in this sector turns on.

There is no profit line. What sits in its place is cost per unit of outcome, measured against a budget fixed outside the organization. And two economies usually run at once: cost per beneficiary served, and cost per dollar raised. Improving one at the other's expense is available, it looks like progress on whichever metric was named, and it is the standard wrong answer.

One published engagement account shows the shape with numbers in it. A tutoring client described in a story published by its adviser had reached more than 10,000 children a year before the pandemic and was down to 4,000. In 2020 and 2021, with close to 95 percent of sessions online, 76 percent of students hit their reading growth target.

Notice which quantities appear there. Children reached, share hitting a target, share of sessions delivered one way. Margin is absent. So is revenue per unit, and so is market share. A structure that opens on revenue and cost in that setting has answered a question nobody asked.

That account is a client's own description of a completed engagement, published by the adviser who ran it, which is exactly its limit. An adviser does not publish the account of a client who thought the work was poor.

The one published interview format in the list

Eight of the nine publish nothing about how they hire. One publishes the whole sequence.

The Bridgespan applicant toolkit states: "In first rounds, we schedule one or two case interviews via Zoom video. Final round interviews are conducted in person, in the office you applied for. Final rounds consist of two additional case interviews and one behavioral interview."

Adding those gives three to four case interviews plus one behavioral interview, so four to five conversations in total.

It publishes two further things that are unusual anywhere in consulting recruiting. The source of the cases: "For this reason, our interviewers prepare their interviews based on real cases." And a volume of preparation: "We suggest you practice at least five case interviews prior to your first interview." That is one of very few employers in our whole corpus that names a number of practice cases.

It also closes a route most candidates assume exists: "Bridgespan does not currently offer internships."

One employer out of nine. Anything you read about how the other eight interview was not published by them, and our own page on that employer carries the rest of what it prints, including its posted pay tiers.

How to check any organization in three steps

Every figure on this page is verifiable by a reader in about a minute. The method works for any US exempt organization, including ones we left out.

1. Find the employer identification number. The IRS Tax Exempt Organization Search takes a name and returns the number, the exempt status and the filings on record.
2. Open the filing itself. The IRS publishes Form 990 filings in series, as images and as XML, with no intermediary between you and the document.
3. Read three lines and divide. Total revenue, program service revenue and total functional expenses. Program service revenue over total revenue is the fee share. Revenue minus expenses is the result for the year.

The obligation behind all of this is worth knowing, because it is why the document exists at all. The IRS states on its Form 990 page that "Tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file Form 990 to provide the IRS with the information required by section 6033." Nobody chose to publish this. A statute requires it, which is exactly what makes it usable evidence and exactly why no commercial consultancy has an equivalent.

That is the whole method, and it is the reason this page exists in the form it does. A list you can check is worth more than a ranking you cannot, and a reader who runs those three steps on an organization we did not include will get an answer of the same quality as ours.

One limit to carry with you. The extract our figures come from does not include the headcount line, so no revenue-per-person figure appears anywhere on this page. We looked for it and it is not in the data we could open.

The weights our own drills apply to a sector case

No organization in this sector publishes a rubric, and neither does any commercial firm. The scale below is ours, set by us and read from our own code.

Scope is the one worth dwelling on, because it is where the two competing economies cash out. Getting the unit wrong is the failure mode this sector produces more than any other, and it is the same class of error as sizing a market per person when the buying unit is a household.

The market sizing drill runs in the browser without an account, and how an answer is assessed sets out each weight with the reasoning behind it. For the engagement arithmetic itself, our page on non-profit cases works a cost-per-beneficiary example end to end.

What none of these filings tells you

Five gaps, and the first one is the reason the word top does not appear in the heading above.

Nobody can order this sector by quality. There is no measured ranking, no published outcome data comparable across organizations, and constructing one from revenue would rank a fund conduit first. The list above is ordered by a ratio we computed and it claims nothing about how good anyone is.

The filings do not carry headcount in the extract we opened, so no productivity figure of any kind is on this page.

Eight of the nine publish no pay. One publishes tiered salaries on its postings and that sits on its own page.

Eight of the nine publish no interview format, no acceptance rate and no case example. None of the nine publishes an acceptance rate, which is a constant across all consulting rather than a feature of this sector.

And the 2024 and 2025 fiscal years are absent for eight of the nine. The extract stops at 2023 for them, so every figure here is dated to that year and labeled as such. A reader who needs the current year should run the three steps above rather than trust a figure from a page.

For the structure of the wider industry and the documents that separate one category from another, the types of consulting firm carries the regulatory and filing evidence.

What changed on this sector page, and when

1 October 2026. This replaces a 278-word page. That version was right about the one thing that mattered, which is that it refused to rank, and it had almost nothing behind the refusal.

What has gone: the claim that fee structures differ substantially from commercial work, which was stated without a figure, and the claim that compensation is lower and the work longer-horizon, which nobody read here had published. Both were plausible and neither was sourced, which §6.8 of our own process treats as a market fact passing for a finding.

What survives from it, in expanded form: the economics section, because the absence of a profit line and the two competing economies are the real content of a sector case. It now carries one published engagement with its quantities and its label as an adviser-published account.

Added in this version: a written inclusion criterion and the three exclusions it forces, nine organizations with every figure taken from its own IRS filing, the fee share computed by hand for each and the roughly 74-fold spread it reveals, seven deficits against two surpluses with the tempting causal story shown to break on three rows, two organizations whose revenue fell by 78 and 49 percent across two years, the one published interview format among the nine, and a three-step method that lets a reader check every line here and any organization we left out.
