Reachable Buyer Map

Prepared for Jim McGuirk · CCMS Partners · August 2026
Executive search is a referral business almost everywhere, and referral has a ceiling built into it. It reaches the part of the sector that already overlaps your network and it is silent about the rest. This map is the rest: the nonprofit segments where a senior search actually gets funded, who signs inside each one, and roughly how many staffed organizations sit there. It describes the market rather than your firm.
Human services and community organizations
The largest block in the sector and the one where the chief executive seat turns over most often, because the job carries fundraising, regulatory exposure and a working board at the same time. Also the group least likely to have retained a search firm before, which makes the first conversation an education rather than a bake-off.
Who signs: board chair, chair of the search committee, the outgoing chief executive, chief operating officer.
9,000 to 10,500
US nonprofit employers in human services and community work carrying 50 or more staff
Hospitals, health systems and community health centers
Longest cycles on the page and the largest engagements. The chief executive search is usually already contested by national firms, so the real opening is the second and third seat, where the incumbent firm is often not retained at all.
Who signs: board chair, chief executive, chief human resources officer, chief medical officer on clinical seats.
2,600 to 3,200
US nonprofit health care and social assistance employers at 50 or more staff
Colleges, independent schools and education nonprofits
The most calendar-driven buyer in the sector. Searches open when the academic year ends and close before the next one starts, so the window in which you need to already be known opens and shuts on a schedule anyone can read a year ahead.
Who signs: board chair, trustee search committee chair, head of school or president, chief people officer.
3,000 to 3,600
US nonprofit education employers, from independent schools through small colleges
Associations, professional societies and membership bodies
Governed by elected volunteer leadership on fixed terms, which means the person who buys a search this year is almost never the person who bought one last year. That is a reachability problem and an opening in the same sentence.
Who signs: board president, executive committee chair, the outgoing chief executive, chief operating officer.
2,200 to 2,700
US membership, professional and trade organization employers with paid staff
Arts, culture and museums
High profile, small staff, and a chief executive seat that becomes public the day it opens. The most visible searches in the sector and therefore the most competed for, which argues for being known before the seat opens rather than pitching after it does.
Who signs: board chair, search committee chair, managing director, chief advancement officer.
1,200 to 1,600
US nonprofit arts, culture and museum employers with paid staff
Foundations and grantmakers
Small by count once the ones with no employees are set aside, and unusually valuable, because a foundation board that likes you sits on several other boards. Worth being plain about a limit: staffed and unstaffed foundations are not separated in any public list, so this layer is identified rather than filtered.
Who signs: board chair, governance committee chair, president, chief of staff.
Roughly 900 to 1,200
US grantmaking foundations that employ paid staff; the great majority of registered foundations employ nobody

Where the openings are

1
Your buyer is a board seat, not a job title. Board chairs and search committee chairs rotate on fixed terms, so in most of the organizations above the person who would hire you is different from the one who was there two years ago, and the handover is announced publicly. A channel built on named roles reaches a new chair inside their first months. A network reaches them after the firm has already been picked.
2
Search is bought at a moment, not on a cycle. A resignation, a retirement, an interim appointment, a merger, a finding in an audit. Almost all of those become public within days. Watching several thousand organizations for that announcement is mechanical work, and it is precisely the work a relationship channel cannot do at volume.
3
The credential only separates you if it is heard. A bench of people who have actually sat in the chief executive seat is a real separator in a market full of generalist recruiters, and it separates nothing at all inside a board room that has never heard the name. That is a distribution gap rather than a credibility one, and the two get fixed in completely different ways.
4
Referral is geographic before it is anything else. A network built in one region reaches that region and stops. The segments above are spread across every state, and the board chairs in them are not resistant to a specialist firm, they are simply unaware that one exists with their sector inside it.
Built from public registries, counts banded deliberately. The source covers US employers that file a benefit plan, current to the most recent filing year. Volunteer-run and very small organizations are not published in it, so these figures describe staffed employers rather than the whole registered sector, which is far larger and mostly unstaffed. Sector codes are self-reported.
