Discover the quickest strategies to place a PE-experienced COO without a full search, balancing interim solutions with long-term hiring needs effectively.
The answer up front
- Put a PE-experienced interim COO in seat against a defined mandate now, and keep the permanent search running behind them.
- Vet interim candidates for conversion before they start. If the fit holds, one hire covers both the gap and the permanent seat.
- Interim and retained search run on different clocks. The interim covers the months the value creation plan cannot wait; the search secures the long-term hire.
- “PE-experienced” means an operator who has built what the mandate needs and works beside the CEO, not above them.
- Demand for interim leadership through BluWave grew 65% from January through September 2026 compared with the same period in 2025, per the BluWave Activity Index.
The fastest way to get a COO with private equity experience into a portfolio company is to bring in an interim COO against a defined mandate now and keep the permanent search running behind them. Vet that interim for conversion before day one, and a single hire can cover both the gap and the permanent seat.
Sponsors are already moving this way. Demand for interim leadership through BluWave grew 65% from January through September 2026 compared with the same period in 2025, per the BluWave Activity Index.
From where I sit in Research and Operations, the COO seat is where that shift shows up most clearly. Holds are running longer while the exit market waits, so more of the return has to come from value creation inside the business. A sponsor can tolerate a quiet quarter in plenty of seats. The operations seat, which carries the integration work and most of the margin plan, is rarely one of them.
When does a COO gap justify moving before a retained search?
Move before the search finishes when the COO gap sits on the critical path of the value creation plan. In lower-middle and core middle market portfolio companies, four triggers come up again and again.
- Integration is outrunning the team. A buy-and-build platform has added operating companies faster than its leadership can standardize them. Estimating and labor planning vary from branch to branch, and margin leaks through the gaps.
- The COO left on short notice. The sponsor parts ways with the COO, or the COO resigns, and the operating team rolls up to a CEO who can cover both jobs for a few weeks, not a few quarters.
- A new CEO needs an operator beside them. CEO change is routine under PE ownership: nearly two-thirds of PE firms replace a portfolio company CEO during the hold, according to AlixPartners’ 11th Annual Private Equity Leadership Survey (March 2026). A newly promoted or newly hired CEO often needs a hands-on operator at their side before they need another strategist.
- A transaction sits inside 12–18 months. A recapitalization or sale process is coming, and the business needs operating credibility in seat before lenders or buyers start asking.
If none of these apply, and the business can run steadily while a search takes its course, a retained search on its own may be the right call. Moving first protects the plan. The search still happens.
Which path fits: interim, interim-to-perm, fractional, or retained?
Each path answers a different question about how much operator the business needs and for how long. When the operation needs someone owning it every day, the full-time interim fits, often with conversion on the table.
| Path |
What it is |
Where it fits |
Where it breaks down |
| Interim COO |
A full-time operator on one mandate with a defined end |
An urgent gap, an integration, or a departure that cannot wait for a search |
A vague mandate with no outcomes or end date |
| Interim-to-perm |
An interim vetted up front for openness to converting |
Sponsors who want the option to keep the operator if the fit proves out |
Stopping the permanent search and treating conversion as the plan |
| Fractional COO |
A senior operator working part time, often across several companies |
A steady business that needs operating judgment a few days a week |
A mandate that needs someone owning the operation every day |
| Retained search |
A permanent hire run by a search firm on a retainer |
The long-term seat, scoped against the value creation plan and exit horizon |
Serving as the only plan when the operation cannot wait months |
The economics differ as well. Interim executives engaged through BluWave carry no retainer: the client pays BluWave, and BluWave pays the interim. Retained search firms are engaged directly on their own fee structure, conventionally a retainer billed in installments across the search. Neither path is a cost play. What an interim buys is time on the mandate that a search alone cannot get back.
What does PE-experienced mean for a COO candidate?
A PE-experienced COO has run operations on a sponsor’s cadence and has built the systems the mandate calls for, rather than advising someone else on how to build them. Sponsors on recent BluWave scoping calls describe the profile in consistent terms.
- An operator, not an advisor. Sponsors screen out candidates who read as consultants. They want someone who has stood up estimating discipline, a supply chain function, or a multi-site operating rhythm before and can do it again on a branch floor or in a warehouse.
- Scale that matches the business. A career spent entirely inside much larger organizations can count against a candidate. A mid-sized operation needs someone comfortable setting the weekly meeting cadence and the labor plan, and who has balanced strategy with day-to-day execution recently.
- Beside the CEO, not above them. Where the CEO is new or newly promoted, the COO has to strengthen the CEO’s hand with the team and the board. A candidate who seems to be competing for the top job unsettles everyone.
- Fluent in sponsor rhythm. Weekly sponsor updates, board packs, lender reporting, and a value creation plan with dates on it are the working environment, not a learning curve.
How do you scope an interim COO mandate so the work can start fast?
Scope the mandate around outcomes, and settle the logistics before any candidate is presented. A clean interim COO placement starts there. BluWave scoping calls for interim COOs cover the same ground every time, and a sponsor who arrives with answers shortens everything after it.
- First-100-day outcomes. What does success look like in the first 100 days? Name the results the sponsor will judge the engagement on.
- Scope and authority. Which functions report in, such as operations, procurement, supply chain, and logistics, and how many direct reports come with them.
- Expected duration. Set a planning horizon and a date to revisit it. A bridge to a permanent hire usually runs shorter than a mandate carried through a planned transaction.
- On-site expectations and travel. Days on site each week, and how often the role travels to other locations.
- Start date and budget posture. When the interim needs to begin, and whether fit or price leads the shortlist.
- Openness to conversion. Whether the sponsor wants candidates who would consider the permanent role.
Once the mandate is set, BluWave introduces vetted interim COOs within 24 hours.
In practice. Our team was on a scope review call this summer with a PE-backed specialty distributor that had just parted ways with its COO. The operations team was reporting straight to the CEO, whose background was in operations, but no one expected one person to carry both jobs for long. What started as a warehouse stabilization project had become an enterprise mandate covering operations, procurement, supply chain, and logistics. The sponsor planned on three to six months, and the leading candidate was open to converting to the permanent role. The call reset the candidate profile against the larger scope before the next round of introductions.
Should the permanent search keep running while the interim is in seat?
Yes. Keep the retained search running, and let the interim compete for the job if the fit is there. Sponsors are not trading one for the other: executive search demand through BluWave grew 30% from January through September 2026 compared with the same period in 2025, per the BluWave Activity Index.
Running both changes the math on the permanent hire. With the interim protecting the plan, the search can hold out for the right candidate instead of the fastest one. And if the interim turns out to be that candidate, the sponsor knows it from months of evidence rather than a few rounds of interviews. As one BluWave project lead put it to a sponsor, the aim is to “shrink two transitions to one.”
Plan for an extension in case the search runs long. Vet for conversion in case the interim is the answer.
“The sponsors who handle a COO gap well stop treating interim and retained search as a choice. They put an operator in the seat against a real mandate, keep the search moving, and let the interim earn the job if the fit is there.”
—Scott Bellinger, VP, Revenue, BluWave
The permanent side starts sooner when the search firm already knows the seat. PE-fluent search firms that specialize in operations leadership often keep a warm network of COO candidates, so they calibrate against a scorecard instead of starting a cold search. BluWave introduces exact-fit search firms within 24 hours of the scoping call, and one conversation can scope both the interim mandate and the search.
In practice. A sponsor came to BluWave about 90 days into a COO search for an acquisition-built mechanical contracting platform. The search was moving, but several newly combined operating companies needed help now with estimating accuracy, labor utilization, and change-order discipline. The sponsor was open to an individual operator or a firm. BluWave framed the need as an interim operating leader and offered to vet candidates for interim-to-perm while the search continued. The sponsor was comfortable with either outcome: a true interim alongside the search, or a convert who becomes the permanent COO.
What happens when the permanent COO starts?
Plan the handoff before the interim starts. A clean exit has an overlap with the permanent COO, a written record of what the interim built, and an end point everyone agreed to up front.
Sponsors raise the overlap early in scoping so the operating team and the company’s customers see continuity instead of a second leadership change. Before the overlap ends, the interim puts open initiatives, vendor and customer relationships, the operating cadence, and the metrics they introduced into writing for the permanent COO. Naming what “done” looks like at the start makes the end of the engagement a milestone rather than a negotiation.
If the interim converts, the handoff becomes onboarding: the same person, now with a permanent scope and a longer horizon.
Frequently asked questions
How quickly can BluWave introduce interim COO candidates? Once the mandate is scoped, BluWave introduces vetted interim COOs within 24 hours. Start dates depend on each candidate’s availability and the role’s on-site requirements, which is why settling duration, travel, and start date on the scoping call matters. Sponsors who arrive with first-100-day outcomes defined move from introductions to interviews fastest.
What is the difference between an interim COO and a fractional COO? An interim COO works full time on a single mandate with a defined end, usually covering a leadership gap or an integration. A fractional COO works part time, often across several companies, and suits a stable business that needs senior operating judgment a few days a week. When the operation needs daily ownership, the full-time interim is the fit.
Can an interim COO become the permanent COO? Yes, when the fit holds and the candidate wants the role. Ask about conversion openness at scoping, keep the permanent search running, and judge the interim against the same scorecard as the search candidates. Plan for an extension in case the search runs long, and vet for conversion in case the interim is the answer.
Does an interim COO replace the need for an executive search firm? Usually not. The interim covers the months the value creation plan cannot wait, and the retained search secures the long-term hire against the exit horizon. Running both lets the search hold out for the right candidate. BluWave can scope the interim mandate and introduce exact-fit search firms from the same conversation.
How is an interim COO paid for through BluWave? Interim executives are engaged through BluWave with no retainer required: the client pays BluWave, and BluWave pays the interim. Terms are set per candidate and scope during the introduction process. Retained search firms are engaged separately on their own fee structure, conventionally a retainer billed in installments across the search.
The next move
If a COO seat is open, or about to be, start with one scoping call that defines the interim mandate and the permanent scorecard together. I can connect you with vetted interim COOs and PE-fluent operations search firms within 24 hours of that call. Does a 15-minute conversation make sense to talk through what you have in motion?
