What to Look for When Hiring Your Next COO

The Chief Operating Officer is one of the most consequential and least understood hires a growing company can make. Unlike the CEO, whose role is largely defined by external presence and strategic direction, or the CFO, whose remit is anchored in financial stewardship, the COO exists in the space between vision and execution. They are the person who takes what the organization wants to achieve and figures out how, at scale, it actually gets done.

That makes the COO hire unusually complex. There is no single COO profile that works across all organizations. The right person for one company at one stage can be entirely the wrong person for another. Before you start searching, you need to be clear on what kind of COO you are actually looking for -- because the candidates who fit one version of the role may be entirely wrong for another.

The COO Role Is Not One Thing

Across organizations, the COO title covers a remarkably broad range of responsibilities. In some companies the COO is essentially a second-in-command to the CEO -- a strategic partner who shadows the top of the organization and manages cross-functional execution. In others, the role is primarily operational: running the machinery of the business, overseeing logistics, technology, people, and process. In others still, the COO is a scale-up specialist brought in to build systems around a business that has outgrown its informal ways of working.

Each of these is a genuinely different job, requiring different experience and a different personality. The leadership demands of a scaling company evolve faster than most founders expect, and the COO you need at Series A is often not the same person you need at Series C. Getting clear on the specific version of the role before you start the search is not just helpful -- it is the difference between a shortlist of relevant candidates and months of confused interviews.

Six Qualities That Define the Best COO Candidates

Across the COO searches we have run, certain qualities appear consistently in the candidates who go on to be genuinely transformative in the role. None of these replace functional expertise -- but they are the traits that separate good operators from great ones.

The CEO–COO Relationship: Why It Determines Everything

No hire is more relationship-dependent than the COO. The success of the role hinges almost entirely on the quality of the partnership between the COO and the CEO -- how well they communicate, how clearly responsibilities are divided, and how much genuine trust exists between them.

This means the COO search is, in part, a search for someone who complements the specific strengths and weaknesses of the existing CEO. A visionary CEO who is weak on execution needs a COO who is deeply operational. A CEO who is strong internally but stretched externally may need a COO who can hold the internal organization while the CEO focuses outward. There is no universal formula -- the right answer is specific to the pairing.

When assessing COO candidates, we always encourage CEOs to think carefully about the working relationship they want, not just the skills they need. Cultural fit and working style alignment matter as much at the COO level as they do anywhere in the organization -- perhaps more, because the consequences of a poor partnership at the top are felt across the entire business.

What the Interview Process Should Actually Test

COO candidates are typically experienced executives who are very good at interviewing. The standard questions will give you polished answers. To get to what you actually need to know, the process has to go deeper.

Give them a real problem to solve. Present a genuine operational challenge your business is facing and ask them to walk you through how they would approach it. You are not looking for the right answer -- you are looking at how they think: whether they ask good questions first, how they prioritize, where they look for data, and how they communicate their reasoning.

Talk to people who have worked for them, not just with them. References from peers and superiors tell you about someone's reputation. References from direct reports tell you what it is actually like to be managed by them. Thorough referencing is one of the most consistently underinvested parts of the executive search process -- and at the COO level, it is indispensable.

Test the CEO relationship explicitly. Bring finalists into a working session with the CEO -- not a formal interview, but an actual problem-solving conversation. Watch how they interact. Do they push back constructively? Do they listen? Do they ask the right questions? The dynamic you see in that room is a preview of what the relationship will look like day to day.

Red Flags Worth Taking Seriously

A few patterns come up repeatedly in COO searches that are worth watching for.

They have only ever succeeded in well-resourced environments. Operational excellence in a large, established enterprise with mature systems and deep support functions is a different challenge than building those systems from scratch in a growing company. If a candidate has never had to build the infrastructure they rely on, that gap can show up quickly.

They talk about what they have achieved, not what their teams have. A COO who consistently centres their own contributions rather than the collective outcomes of the people they led is showing you something important about how they see the role.

They cannot articulate where they disagree with the CEO. The best COOs are not extensions of the CEO's thinking -- they are a genuine counterpart. A candidate who cannot identify areas of constructive tension in their past CEO relationships may not be wired to provide the honest challenge the role requires.

Timing the Search Correctly

Most companies come to the COO search too late -- when the operational pain is already acute and the pressure to hire quickly compromises the quality of the process. Senior searches take time to run well, and the COO role -- with its high relationship dependency and broad remit -- takes longer than most to get right.

The indicators that a COO hire is coming tend to be visible well in advance: the CEO is increasingly stretched across too many functions, execution is inconsistent despite good strategy, or the organization is approaching a scale inflection that its current operating model was not built for. Recognizing those signals early and building the search into your leadership planning before they become a crisis gives you the time to do the search properly.

If a COO search is on your horizon and you want to talk through the profile, the process, or what the market looks like right now, we would be glad to have that conversation.
