You tried it once already. You hired a general manager, or an ops director, or someone with COO on the business card. Six months in, the decisions were still landing on your desk. Twelve months in, the person was gone and you were doing both jobs again. You still feel it. And now when someone says you need a second in command, the honest answer in your head is no thanks, I will sell first.
I understand that answer. I also think it is wrong, and expensive. So let me answer the question properly. What does a COO do, in a company your size, and which kind do you actually need?
I have been the CEO who needed one. I built Arcules from zero to over 150 people and sold it to Canon, then ran a Canon company as its youngest standalone CEO. For a stretch I held the CEO, CFO and CTO seats at once. That is not a badge. It is a symptom.
A COO is the leader who owns how the work gets done, so the CEO can own what the company does next. In a $5M to $50M company that means the operating cadence, the weekly numbers, the managers and the follow through.
Quick answer: A COO, or chief operating officer, runs the inside of the company: operating cadence, weekly numbers, delivery, the managers below the leadership team, and follow through on decisions. The CEO keeps vision, key customers, capital and culture. Research names seven COO variants. Most owner led companies between $5M and $50M need an executor or integrator first, often fractional, one to three days a week.
Leaders ADAPT places fractional COOs from its own bench and stays accountable for the engagement, priced as a fixed monthly fee quoted after the first call. Every statistic on this page belongs to its publisher, is linked, and carries the date I read it. If their page has changed, their page wins. No source named here pays us.
What does a COO do in a $5M to $50M company
In a large company the COO title can mean almost anything. In a company your size it means one thing. The COO is the person who makes the company run the same way on the days you are not there.
The US Bureau of Labor Statistics describes top executives as the people who set goals and policies, oversee the making of products and delivery of services, appoint managers and find ways to cut costs and improve performance (BLS Occupational Outlook Handbook, read October 2026). It lists chief operating officers as executives who manage a part of the organization, with duties that vary. That is accurate and not much help.
Here is the useful version. A COO in an owner led company owns five things.
The cadence. The weekly leadership meeting, the scorecard, the quarterly priorities, and the discipline that the meeting happens when you are travelling.
Delivery. Whatever the company makes or provides, it ships on time and in full, and someone other than you knows why it did not.
The managers. Hiring, coaching and, when needed, removing the people one level down. Most owners have never had anyone between them and the front line who could do this.
The numbers that move weekly. Not the annual budget. The five or six figures that tell you on Monday whether this week will be a good one.
Follow through. You decide on Tuesday. The COO makes sure it happened by Friday, and tells you plainly when it did not.
What you are buying is not more management. It is fewer decisions on your desk.
COO responsibilities, split between COO and CEO
The fastest way to kill a COO hire is to leave the split vague. Write it down before the person starts. This is the split I use as a starting point with owners.
| Area | The CEO owns | The COO owns |
|---|---|---|
| Direction | Vision, three year picture, what we stop doing | Turning the annual plan into quarterly priorities and weekly work |
| Customers | The top accounts and the relationships that need the owner | Service quality, delivery, complaints, renewals in the normal course |
| People | The leadership team, culture, the hard calls at the top | Managers below the leadership team, hiring process, performance reviews |
| Numbers | Capital, pricing strategy, lenders, investors | Weekly scorecard, margin by line, cost control, capacity |
| Meetings | The quarterly and annual sessions | The weekly leadership meeting and every recurring operating review |
| Process | Which few processes define the company | Documenting, running and improving all of them |
| Problems | The issues only the owner can solve | Everything else, solved before it reaches the owner |
The last row is the one that matters. If problems still travel upward by default after two quarters, the split is not working, and it is rarely the COO's fault. Our operations manual and accountability chart guides cover how to make the split visible to the whole team.
The seven COO variants, and the one you need
In 2006 Nathan Bennett and Stephen Miles studied the role for their book Riding Shotgun and a Harvard Business Review article, and named seven types of COO: executor, change agent, mentor, other half, partner, heir apparent and MVP (Georgia Tech, read October 2026). Read the list and one thing is clear. The same title hides very different jobs. In my experience most failed COO hires are a mismatch between the type the CEO needed and the type the CEO hired.
Their list was built on large companies. For owner led companies I keep five of theirs, merge two, and add one they did not have.
1. The executor. Turns the CEO's decisions into results. Builds the cadence, runs the managers, closes the loop. This is the most common need below $50M, by a distance.
2. The change agent. Brought in for a turnaround, a merger, a new system or a growth push the current team cannot run. Useful for a defined period. Expensive to keep after the change lands.
3. The mentor to a young or first time CEO. An experienced operator next to a founder who is new to running people. Rare in owner led companies, because the owner is usually the experienced one.
4. The other half, or partner. Complements the CEO's weak side. The visionary who hates detail gets the detail person. Bennett and Miles split this into two types. At your size the split matters less than the fit.
5. The heir apparent. Hired or promoted to take the CEO seat in two to four years. Relevant if you plan to step back or sell to a buyer who wants a successor in place. Dangerous if you have not decided that yet.
6. The MVP. Given the title to keep a strong performer from leaving. I see this more often than I would like. It solves a retention problem and creates an operating one.
7. The finance led or integrator COO. My addition. In many owner led companies the operating problem is cash, margin, pricing and the cadence around them, and the right COO is an operator with a finance spine. In an EOS company the same seat is called the integrator. Our GM vs COO vs integrator comparison and the EOS integrator guide draw those lines.
Which one does a $5M to $50M owner need? In most cases the executor, with some of the other half. You need someone who loves the detail you avoid, runs the Monday meeting, and holds the managers to the numbers. If the problem is mostly cash and margin, the finance led shape. If you are honestly planning an exit in 18 months, look hard at the heir apparent question first, because a buyer will.
The variant you should not hire first is the MVP. If the only reason for the title is that a loyal person wants it, give them a raise instead.
Signs you need a COO now
Owners rarely say "I need a COO". They say "just tell me what to do". These are the signs I listen for.
- Delegation boomerangs back. You hand something off on Monday and it is on your desk again by Thursday.
- You are in every decision that touches money, a customer complaint or a hire.
- Managers bring you problems, not recommendations.
- You avoid one on ones because each one turns into you solving their week.
- Growth has stalled at roughly the size you can personally hold in your head.
- A buyer, lender or board member has asked who runs the company when you are away.
- You tried a GM or COO once, it failed, and you have quietly decided not to try again.
Three or more is a strong signal. The seventh one deserves its own sentence. A failed hire is information, not a verdict. Usually it tells you the decisions never moved, not that the seat was wrong. Our hire a COO guide covers how to run the search the second time, and our page on key person risk explains what the absence of a second in command does to the price a buyer offers.
Fractional COO or full time hire
For most owners under about $20M I suggest fractional first. A senior operator one to three days a week builds the cadence, finds the gaps and shows you what the seat really needs. You learn whether you can hand over the decisions before you commit to a full salary.
The full time comparison is real money. The BLS put the median annual wage for chief executives at $206,420 and for general and operations managers at $102,950 in May 2024. A seasoned COO in a growing company sits somewhere between those two figures before bonus and benefits. Our fractional COO cost page has the published market rates for the part time shape.
The role is also not going away at the top. McKinsey reported that 40 percent of leading companies had a COO in 2022, up from an all time low of 32 percent in 2018, citing Crist Kolder Associates (McKinsey, October 2022). Back in 2015 strategy+business wrote about the decline of the seat, from 48 percent of Fortune 500 and S&P 500 companies in 2000 to 36 percent in 2014. Large companies keep debating whether they need one. Owner led companies rarely have the option of not having the work done.
Switch from fractional to full time when the work fills five days, when the managers need daily leadership, or when the fractional retainer approaches a full time salary for the same scope. A good fractional COO names that point in advance. The fractional COO page covers the engagement shape in detail, and the COO advisor page covers the lighter version, an hour or two a week with a sitting COO, for owners who already have someone in the seat.
If you are unsure whether you need a COO, a chief of staff or an integrator, read chief of staff vs COO vs integrator before you write a job description.
Where AI fits in the COO seat
The operations seat is where AI pays back fastest in a company your size, and where it is most often wasted.
First, the scorecard. A COO with clean data and an AI assistant can pull the weekly numbers, flag the outlier and draft the commentary in an hour instead of a day. The meeting starts with the conversation instead of the spreadsheet.
Second, the process library. Most owner led companies run on knowledge in three people's heads. AI tools can turn recorded walkthroughs and old emails into a first draft of the operations manual, which a manager then corrects. That is weeks of work saved.
Third, follow through. Meeting notes, action items and reminders are now cheap to automate. For an EOS style company, our AI for EOS companies guide shows where this sits in the weekly and quarterly rhythm.
Where AI does not belong is the judgment call. Which manager to move, which customer to let go, what to say to a team after a bad quarter. Our page on what not to delegate to AI is the longer version. McKinsey's COO practice makes a related point, that a COO should find the few COO only topics and delegate the rest (McKinsey, March 2026). AI is a good place to delegate the rest. It is not the COO.
What a COO does not fix
I say this on the first call, because it saves a year and a failed hire.
A COO does not fix a CEO who will not let go. If you keep the decisions, the COO becomes an expensive assistant and leaves within a year. The work that changes this is yours, and it is why I pair the COO seat with the owner's own development and with leadership team development. A strong operator on top of a leadership team that cannot run a meeting without you is still a company that depends on you.
A COO does not set the vision. If you do not know where the company is going in three years, the COO will run very efficiently in no direction.
A COO does not replace a missing sales engine. If the problem is pipeline, you want a revenue leader first, and a good COO tells you that in month one.
A COO does not become your therapist or your only confidant. That is what a peer group, an advisor or a board is for.
Who is on the bench for this
Chris Geddes is a fractional COO on the Leaders ADAPT bench. Chris is an operator who pairs operations leadership with AI transformation work in owner led companies. He is the one I bring when the cadence needs building and the company is also ready to put AI into the weekly work.
Marina St. Cyr is a fractional COO on the bench. Marina runs operations leadership for owner led companies, is strong on detail, and owns the cadence and the follow through. She is the executor shape from the list above, the person who makes Tuesday's decision real by Friday.
Steve Shaw takes COO seats where the operating problem is finance led. Steve has twenty years in finance leadership and works on cash, margin, pricing and the operating cadence around them. When the variant you need is the seventh one, Steve is the call.
Every engagement runs through Leaders ADAPT. I take the first call, match the partner, and stay in the room. You get a CEO who has needed a COO and an operator who has been one, on the same side of the table. The full bench, including the other seats, is on Fractional Executives and Advisory, and the ring hub on fractional executive services explains how the seats fit together.
What a COO does, FAQ
What does a COO do in a small or mid sized company?
In a company between $5M and $50M a COO owns how the work gets done. That means the operating cadence, the weekly numbers, the managers who run delivery, hiring and firing below the leadership team, and the follow through on decisions the CEO makes. The CEO keeps vision, the biggest customers, capital and culture. The COO makes the rest happen without the CEO in the room.
What is the difference between a COO and a CEO?
The CEO decides where the company goes and owns the outside world, meaning customers, capital, the board and the story. The COO owns the inside, meaning the people, processes and numbers that turn those decisions into results every week. In a healthy pair the CEO sets three priorities a quarter and the COO makes sure nothing else gets in their way.
What are the seven types of COO?
Nathan Bennett and Stephen Miles named seven in 2006, the executor, change agent, mentor, other half, partner, heir apparent and MVP. For owner led companies I merge other half and partner into one, because the split matters less at that size, and add the finance led or integrator COO, which is the shape most $5M to $50M companies actually need.
How do I know if I need a COO?
You need one when delegation keeps boomeranging back, when you are the bottleneck on decisions that should not need you, when managers wait for you to solve their problems, when growth has stalled at the size you can personally hold, or when a buyer would see you as the whole company. Three of those at once is a strong signal.
Should my first COO be fractional or full time?
For most owners under about $20M I suggest fractional first. One to three days a week from a senior operator builds the cadence, finds the gaps and shows what the seat really needs, at a share of a full time cost. Once the work fills five days and the managers need daily leadership, hire full time and let the fractional COO help pick the person.
Why did my general manager or COO hire fail?
Most of these hires fail for the same reason. The owner hired a person but never handed over the decisions, so the new leader had accountability without authority. Within months the work came back to the owner and the hire left. The fix is to write down which decisions move, agree the weekly numbers, and keep your hands off them for at least two quarters.
What does a COO not do?
A COO does not fix a CEO who will not let go, does not set the company vision, does not replace a missing sales engine, and does not become the owner's therapist. A good COO makes the gaps visible fast. Closing the ones that sit with the owner is leadership work, which is why Leaders ADAPT pairs the COO seat with the owner's own development.
How much does a COO cost?
The US Bureau of Labor Statistics put the median annual wage for chief executives at $206,420 and for general and operations managers at $102,950 in May 2024. A senior COO in a growing company usually sits above the second figure before bonus. Fractional COO rates vary by days per week. Leaders ADAPT quotes its engagements per engagement after the first call.
Start with the list of what comes back to you
Every owner who calls me about a COO has a list in their head of the things that keep landing back on their desk. Most have never written it down. That list is the job description.
Tomorrow morning, do one thing. Keep a sheet of paper next to you for one week. Every time a decision, a problem or a question comes back to you that someone else should have handled, write it down. At the end of the week, sort it into the seven rows of the table above. The rows with the most marks are the COO's first quarter.
What the first conversation looks like
It is a 30 minute call with me, not a sales rep. You bring the list of what keeps coming back to you, and if you tried a GM or COO before, what happened. I tell you which of the seven variants you need, whether the gap is in the seat or in how decisions move, and whether a fractional COO from the bench is the right first step or whether you need something lighter. If the answer is a better operations manager, I say so.
If we go ahead, Chris, Marina or Steve joins the second call, we agree the scope in days per week and the three outcomes we write down, and the fee is fixed monthly and quoted after that call. I stay in the room for the length of the engagement.
Your step for tomorrow morning: take the free assessments so I can see how the company depends on you before we talk about the seat. Then book a fit conversation. Hiring a COO is the easy part. Knowing which one you need is what the call is for.
