What Does a COO Actually Do in a Small Business?

Forget Everything You’ve Heard About the COO Role

When most people think “COO,” they picture a corporate executive at a Fortune 500 company. Someone managing global supply chains and reporting to a board of directors.

That’s not the COO role we’re talking about.

In a 50 to 150 person, owner-operated business, the COO looks completely different. They’re not a figurehead. They’re your operational right hand. The person who takes the weight of daily execution off your plate so you can focus on vision, relationships, and the strategic decisions that only you can make.

If you’re a founder wondering whether you need a COO, this post will demystify the role: what they actually do week to week, how the founder/COO partnership works when it’s healthy, and how to know if you’re ready.

The 5 Core Responsibilities of a Small-Business COO

In a smaller company, the COO wears more hats than their Fortune 500 counterpart. But the job boils down to five core areas:

1. Operational Execution

The COO owns the day-to-day engine of the business. They make sure work gets done, deadlines get hit, and the machine runs without the founder having to micromanage every moving piece. This includes production, service delivery, project management, and quality control.

2. People Leadership

In a founder-led business, the COO often becomes the primary people leader. They run one-on-ones with department heads, manage performance, resolve conflicts, and build the kind of accountability structure that allows people to grow. The founder may set the cultural tone, but the COO enforces it daily.

3. Process and Systems

Growing companies are full of workarounds, tribal knowledge, and undocumented processes. The COO’s job is to bring order to that chaos. Standardizing workflows, implementing systems, and creating the kind of operational infrastructure that actually scales.

4. Accountability and Metrics

The COO builds the scoreboard. They define KPIs, track progress, run leadership meetings, and hold the team to its commitments. Without this function, most founder-led businesses operate on gut feel. Which works until it doesn’t.

5. Strategic Execution

The founder sets the direction. The COO makes it happen. They translate big-picture vision into quarterly priorities, resource plans, and cross-functional initiatives that actually get completed.

A Week in the Life: What a COO Actually Does

Here’s what a typical week might look like for a COO in a $25M home services company with 80 employees:

  • Monday: Weekly leadership meeting. Reviews KPIs, addresses operational bottlenecks, and aligns the team on priorities for the week.
  • Tuesday: One-on-ones with department heads. Coaches the operations manager through a staffing challenge. Reviews a process improvement proposal from the field team.
  • Wednesday: Site visit to a branch location. Walks the floor, talks to frontline staff, identifies a training gap that’s been causing rework.
  • Thursday: Works with the finance team on monthly P&L review. Flags a margin issue in one service line and drafts a corrective action plan.
  • Friday: Strategy session with the founder. Discusses progress on quarterly Rocks, reviews candidate pipeline for an open VP role, and plans for an upcoming leadership offsite.

Notice what’s missing from that list? The founder’s direct involvement in daily operations. That’s the entire point.

The Founder + COO Dynamic: How the Best Partnerships Work

The founder/COO relationship is the most consequential partnership in any small business. When it works, the business accelerates. When it doesn’t, it creates confusion, power struggles, and culture fractures.

What healthy looks like:

  • Clear lanes. The founder owns vision, culture, and key external relationships. The COO owns execution, people management, and operational performance. There’s mutual respect for each other’s domain.
  • Radical candor. The COO can push back on the founder’s ideas without fear. The founder trusts the COO enough to share concerns early, not after they’ve festered.
  • Complementary wiring. The best founder/COO duos are not clones of each other. A visionary, big-picture founder paired with a detail-oriented, process-driven COO creates a leadership team that’s greater than the sum of its parts.
  • Shared values, different strengths. Alignment on core beliefs (how you treat people, what integrity means, what the business stands for) is non-negotiable. Alignment on working style is optional and often counterproductive.

Self-Assessment: Are You Ready for a COO?

Answer these five questions honestly:

  1. Are you spending more than 50% of your time on operational tasks instead of strategic work?
  2. Do your direct reports regularly wait on you for decisions, approvals, or direction?
  3. Have you shelved at least two major initiatives in the past year because there was no one to lead them?
  4. Would your business run for 30 days if you stepped away completely?
  5. Are you emotionally ready to trust someone else with the keys to daily operations?

If you answered yes to three or more, you’re likely past the point where a COO would help. You’re at the point where not having one is holding the business back.

What to Look for When Hiring a COO

Hiring a COO for a small business is not the same as hiring one for a large corporation. Here’s what actually matters:

  • Relevant scale experience. You want someone who’s led teams of 50 to 200, not 5,000. The muscle memory of a large-company COO often doesn’t transfer to an environment where the leader has to roll up their sleeves.
  • Builder mentality. Your COO needs to build systems, not just manage existing ones. In a growing company, the infrastructure doesn’t exist yet. You need someone who thrives in ambiguity.
  • Emotional intelligence. In a founder-led business, the COO has to navigate the founder’s emotional connection to the business. That requires empathy, patience, and the ability to challenge without threatening.
  • Values alignment. Skills can be assessed on a resume. Values can’t. The COO will shape your culture every single day through the standards they set and the behaviors they tolerate.
