Interim executive search is a search for a senior leader who can take the seat now, for a defined stretch, and leave it in better shape than they found it. The product is cover and pace. The chair is empty. Notice on the permanent hire is months. The work will not wait.
That is the whole machine. Most things called interim are a contractor with a better title, or a retained search that someone tried to hurry.
What people mean by interim executive search
They do not mean a temp desk and a timesheet. They mean a CFO who can close the next two quarters, a country lead who can hold DACH while the permanent person works their notice, an operator who can take a portco through the first hundred days. The person has done this kind of landing before, or they are between seats and can walk in.
It is not retained search run at speed. A permanent hire is judged on what must be true in eighteen months. An interim is judged on what must be true in ninety days, and on whether they can leave without a mess. Confusing the two is how you hire a caretaker and then discover you needed a builder — or hire a builder and then discover nobody asked them to leave.
It is also not a consultant. A consultant writes from outside the building. An interim sits in the chair, signs, and is hated or loved as a line manager. Fractional and part-time advising can be useful. They are a different product. If the team needs a boss on Monday, a day a week is not cover.
The useful test is boring. If the permanent person cannot start until March, and January will punish an empty chair, you have an interim problem. If you want someone who will still be here in three years, you have a search. Do the search.
The working objects
If you only remember four things, remember these. Everything else is a rate card.
01
The gap
Why the chair is empty, and when the gap ends
02
Ninety days
What must be true when they have landed
03
Who can start
Notice already served, or a career interim
04
The exit
Handoff, convert, or a clean leave
The gap. Why the seat is open, and for how long. Replacement after a sudden exit is a different assignment from a transformation with a date on it. A PE first hundred days is a different assignment from cover while a retained search runs. If nobody can say when the gap ends, you will still have this person in year two.
Ninety days. What must be true when they have landed — the close, the team that was about to leave, the number the board will ask for in the next meeting. Not a vision. Not “stabilize and see.” If two stakeholders would score the same interim differently after a quarter, the brief is not finished.
Who can start. Career interims, people already between seats, people whose notice is measured in weeks not quarters. A brilliant sitting CRO with six months of garden leave is the wrong inventory. The map still matters — the wrong building still produces the wrong person — but availability is a first filter, not a last one.
The exit. Handoff to the permanent hire, conversion, or a clean leave when the work is done. Write it before anyone starts. An interim who was never told whether they could stay will run the assignment as a campaign for the job. The team will feel it.
How an interim search actually runs
1. Name the gap
Someone has to say, in a room, why the chair is empty and what “done” looks like. Cover until a named person starts is one assignment. A carve-out that ends at close is another. “We need someone senior in the building” is not an assignment. It is a mood.
Write the end date as a range if you must. Write it. An open-ended interim is how acting titles become facts.
2. Write the ninety days, not the career
The scorecard is shorter than a permanent brief and stricter. Reporting line for the stretch. Decision rights — what they may sign. The two or three outcomes they will be judged on. What they must not do: sell the company, rebuild the grade structure, hire their own successor unless that is the job.
If the brief secretly wants an eighteen-month transformation and a culture change, you do not have an interim. You have a permanent search you are afraid to start.
3. Look for people who can walk in
Career interims first — people who have landed in a cold building before and left without drama. Then people between seats. Then sitting executives whose notice is actually short.
This is the part that used to take a specialist book of names and still does, more than a permanent map does. The universe of people who can start on Monday is smaller than the universe of people who could do the job in a year. Talent mapping still names the companies and seats. The cut is different: start date, not only fit.
A pipeline of people you would call for cover is worth keeping if you will see this gap again. A folder of last year’s interims with no dates is a graveyard, same as any other.
4. Assess for landing
Have they done this kind of entry. Will the team still be there in a month. Can they live with authority that expires. The write-up should say what they will do in the first weeks, not how they would run the company in 2029.
References on interims are specific: the last chair they sat in, the mess they inherited, whether finance would have them back. Nominated references on a career interim are part of the product. Independent ones still matter.
5. Put the commercial terms in writing
Who employs them — the client, a provider, their own company. The rate, the length, what happens if the gap shrinks or grows. Conversion: allowed, priced, or forbidden. Off-limits for the next search if they will see the market from inside.
Arguments about those things in week six are how assignments go sour. The AESC’s useful point still holds: put the engagement in writing. Interim is not an exception.
6. Run it next to the permanent search, or instead
If the chair must be held while you hire for eighteen months, say so. The interim is cover. The retained search is the hire. Do not let the panel stop meeting because someone competent is already in the building. That is how cover becomes the strategy.
If the work itself is time-boxed — a close, a carve-out, a turnaround with an end — there may be no permanent seat. Then interim is the search. Do not run a phantom retained process to make the org chart look serious.
7. Make them leave well
Handoff notes. A week with the permanent person, if there is one. A last board that does not reopen the scorecard. Pay what you agreed through the end date.
An interim who is walked out on a Friday because the permanent person arrived on a Thursday will tell the next six rooms. The market for people who can start on Monday is small. You will meet them again.
Interim versus permanent
They can run in the same week. They are not the same clock.
Interim
A defined stretch
- The chair cannot stay empty
- What must be true in ninety days
- People who can start
- An exit, written down
Permanent
A signed mandate
- What must be true in eighteen months
- A live scorecard, owned by a panel
- Longlist that narrows to a slate
- The client's calendar, then notice
| Interim | Permanent | |
|---|---|---|
| Why it exists | The chair cannot stay empty | A hire you intend to keep |
| Scorecard | Ninety days, then an exit | Eighteen months, then a team |
| Inventory | People who can start | People who would move |
| Clock | Days or weeks to a start | The panel, then notice |
| Money | A rate for the stretch, plus the search | A fee for the work, usually in stages |
| Failure | No exit, or a caretaker when you needed a builder | The panel cannot decide |
Anyone promising a permanent C-suite start in three weeks is either filling from a bench they already had, or skipping the map. Anyone promising an interim in three months has not understood the product.
Who actually runs it
A specialist interim firm. A book of people who have landed before. Useful when start date is the scarce thing. Weak when they cannot write a scorecard and send you “available now.”
A search firm with an interim practice. Useful when the same market will also need the permanent hire, and one owner should see both. Weak when the interim is treated as a leftover of the retained process.
Inside. An acting appointment from the number two, or a PE operator on secondment. It can be the right cover. It fails when the acting person is campaigning for the job, or when nobody has permission to decide they will not stay.
Nobody. The usual mess. The chair stays empty, the team leaves, and the permanent search inherits a worse brief.
Where interim searches actually fail
We map and longlist for independent firms, including cover while a permanent search runs. The pattern is boring, which is why it keeps happening.
The brief is “keep the lights on” and then the board asks for a transformation in week three. Conversion was never discussed, so the interim runs a campaign. The permanent panel stops meeting because someone competent is already there. The only people presented are available, not able. The assignment has no end date. The rate was agreed and the decision rights were not.
None of those are inventory problems. Adding more names who can start on Monday will not fix them. Writing the gap, the ninety days, and the exit will.
The other failure, quieter: using interim to avoid a retained search. The seat is permanent. The fee looks cheaper on a slide. Six months later you still have a caretaker, and the people you actually wanted have taken something else. That is not pace. That is a delay you paid for by the day.
How we know
Topliner runs the research loop — maps, longlists, scoring, outreach — for independent executive search firms. Some of those mandates are cover: the chair is empty, notice is months, someone has to sit in it. Interim executive search is that clock. A permanent search is the other one. We see both, and we see the week where the panel pretends they are the same.
If you run a firm and you want the cover mapped without living in a spreadsheet, talk to us. The judgement stays yours. That is the point.
Questions people actually ask
What is interim executive search?
A search for a senior leader who can take a seat for a defined stretch — often months, not years — and start while a permanent hire is still on notice, or while the work itself is time-boxed. The product is cover and pace. It is not a cheaper retained search.
What is an interim executive?
A sitting or career interim at a level where the empty chair is expensive — CFO, country lead, CHRO, an operator on a portco. They are employed for the assignment, or contracted through a provider, with an end date. They are not a temp, and they are not a consultant writing a deck from outside the building.
How is interim executive search different from retained search?
A retained search hires the person who will still be right in eighteen months. An interim search hires the person who can land in ninety days and leave the chair better than they found it. The scorecard, the clock, and the fee are different. How a permanent search runs is a different page.
When should you hire an interim executive?
When the seat cannot stay empty for the length of a notice period. A sudden departure, a transformation with a clear end, a PE first hundred days, a carve-out, a brief that is not finished and a business that cannot wait. If you actually want a permanent person and you are calling it interim to move faster, run the permanent search.
How long does an interim executive assignment last?
Long enough to close the gap, short enough that everyone still knows it is temporary. Many sit in the six-to-eighteen-month range. A weekend of cover is not an executive assignment. An interim who is still there in year three was a permanent hire you refused to name.
Can an interim executive become the permanent hire?
Sometimes. Write the conversion terms before anyone starts. An interim who was hired to hold the fort, then offered the seat because the panel got tired, is a search you skipped. If conversion is on the table, say so on day one — to the person, and to whoever is running the permanent process.
