Headhunter, Recruiter, Search Firm, Club

Four kinds of counterparty will contact an executive, and a house filling a consequential seat meets the same four. They present almost identically. Discreet. Senior. Off-market. A very small number of clients. None of those words costs anything to say, no title here is protected, and one person can print recruiter on one card and headhunter on the next without changing anything about how they work.

Two facts do not travel that cheaply: who the person works for, and what event releases their fee. Those settle the rest — how fast a name moves, whether a brief is shared, whether the relationship survives the seat being filled. Both are askable in a first conversation, which makes this a taxonomy a reader can use rather than a position a firm can claim.

The two questions

The first is duty. All four are paid by companies, but not for the same thing. Some work a requisition, a line in a hiring plan. Some work a mandate, a piece of signed scope. One works for a person across a career and takes its fee from whichever house eventually hires them.

The second is timing, and it predicts behaviour. Money arriving on a signature rewards speed; money arriving on a schedule rewards thoroughness and is indifferent to the result. Neither incentive is corrupt, and both are visible before anything is agreed.

The recruiter: paid for closing requisitions

A recruiter works requisitions. The seat is defined before they arrive, the specification is written, and the measure of the work is how many close. Their supply is the population of people who are looking, reached through the channels looking people use — the same public pools every agency fishes, which is why two agencies on one seat so often return the same names.

That is a real skill, underrated by executives who have never had to fill a floor in a quarter: where a market is liquid and the role well understood, nothing beats a capable recruiter for throughput. The model fails at one thing, structurally rather than through want of effort. It cannot reach a person who is not looking, because it assumes an advertisement will be answered.

The contingency headhunter: paid only if their name signs first

The contingency headhunter solves the reach problem by approaching people directly. Nobody applied; the researcher found them. That is a genuine advance, and its economics are where attention belongs. A contingency firm is paid only when its candidate signs, and it is very often not the only firm on the brief: several firms hold the same specification, and the first to produce the appointed name collects. Its fee is usually the lower of the two search prices — retained search fees run higher than a contingency firm’s, as Robert Half notes — and low for a structural reason: the firm can run the entire search, approach everyone worth approaching, and be paid nothing.

The consequence follows without anyone behaving badly. A firm that may earn nothing cannot spend weeks it might not recover, and under a shared brief the rational move is therefore to submit a name early rather than accurately, before the person has fully agreed. Discretion is expensive; speed is free. That is the arithmetic behind an approached executive finding their name somewhere they did not put it. Well suited to a deep active market, badly suited to anything confidential.

The retained search firm: paid for the process

A retained firm inverts the timing. It is engaged exclusively, paid in instalments across the search, and the money is owed whether or not the seat is filled. One firm’s price is on the public record: Korn Ferry’s annual report for the year to April 2025 puts the fee on its search work at generally one-third of the placed candidate’s estimated first-year cash compensation, plus a charge for expenses. The premium over the contingency price is the part worth reading. It is not a surcharge for a better shortlist — both instruments can reach the same people — it is the price of the searcher’s certainty, and the buyer meets it by taking the outcome risk off the firm’s ledger onto their own. That purchase is exactly what the retainer is, and who ends up carrying what is argued out separately in what a retainer actually buys.

The point here is more generous, because that certainty is not always a consolation prize. There are mandates where paying for the process is the correct purchase rather than a compromise: a board appointment that will be scrutinised afterward, a regulated seat where the method has to be defensible, a function nobody has built before and where the map has to outlive the search. The client is buying the process itself, paid for whether or not it produces a name, and a success-only fee does not buy that: it pays for a signature, not for a quarter spent on a search that might produce nothing.

What it does not buy is a relationship that outlives the mandate: duty starts with the scope and ends with the placement, by design. Honest talent mapping is valuable work, and not an obligation to the mapped.

The club: paid by the house, holding the person

The fourth instrument is usually taken for a nicer version of the third. It is not, and both answers say why.

Who it works for: on the talent side, the member. Membership is free for talent, forever, the companies pay to reach the room, and a member’s salary is entirely their own — which removes the mechanism by which a person becomes inventory. The relationship is career-long: members are members for life, kept on the radar between moves and re-introduced when the right mandate appears. Trajectory over transaction, an obligation with no completion event. A Talent Strategist owns the mandates; a Talent Concierge stays with the member through every role process, complimentary.

When it is paid: by the house, on a signed hire. That is the standard engagement, No Cure, No Pay, so nothing is owed for effort — the stance being not another recruitment agency, but the growth partner of the houses it serves.

Those two answers produce the conduct; nobody has to promise it. Every mandate is exclusive to The Quantum Club and the vast majority are never publicly listed anywhere, so no brief races a competitor with a name attached and the early submission has nothing left to win. Every approach is confirmed with the principal first, which is a delay only a firm racing nobody can afford to take. There are zero public job posts, ever; mandates arrive through a direct line to founders, owners and the C-suite rather than an inbox — the first instrument’s reach problem answered from the supply side instead of with a better advertisement. Interest is reviewed privately and never shared with anyone, including a current employer, without explicit consent: a member who will still be a member in a decade cannot be spent on one introduction.

The limits sit in the same place. A structure built to hold a person for a career is slow at volume, useless to a house that wants several firms racing, and willing to decline a match that would bend a life around a seat. Bought for throughput it is the wrong instrument.

The four, on the two questions

Instrument	Works for	Paid when	Best at	Fails at
Recruiter	A requisition	On placements closed	Liquid markets, defined roles, throughput	Anyone who is not looking
Contingency headhunter	A shared brief	Only if their name signs first	Many names quickly, active markets	Discretion; the name travels early
Retained search firm	One mandate, exclusively	On schedule, win or lose	Exhaustive mapping, defensible appointments	Duty ends at the placement
Members club	The member, across a career	By the house; as standard, on a signed hire	Unlisted seats, confidential moves, arcs	Volume, and anything urgent

Read the second column downward. Three of the four work for a seat, and their interest in the person ends when it is filled. That is not an accusation; it is the scope they were engaged under.

Three questions that cannot be improvised

Who cleared this introduction, is your firm the only one on this brief, and what happens once the seat is filled. The first two are buy-side diligence, put to a firm in full — with the club’s own answers and what each one costs it — in the firm nobody audits. The third is the one the taxonomy turns on, and no instrument scoped to a mandate is engaged to answer it at all.

Each is settled by the model rather than the manners. A firm on a shared brief cannot claim a clearance that does not exist to give, and a mandate-scoped counterparty has no answer to the third beyond a database entry. A career-scoped one holds a standing position and gives it in the same words every time, which is the tell: rehearsed answers vary, structural ones do not.

Matching the instrument to the seat

None of this is a ranking. A house filling a floor of regional managers should call a recruiter; one appointing a chair under scrutiny should retain a firm and pay for the process. The mistake is rarely the wrong instrument — it is not knowing which one is across the table, and assuming the four differ by quality when they differ by structure. The wider map of how unlisted seats get filled is set out in the unlisted market.

Admission is earned, never bought. An executive who would rather be known by the fourth kind of counterparty than found by the first can request an invitation, read in private. Every application is answered. The exceptional are answered personally.
