Hiring the right COO: types, fit, and how to make the partnership work

Executive overview

Most CEO-COO hiring fails because founders treat the role as generic. There are seven distinct COO types — each suited to a different business situation — and hiring the wrong type costs 15x their annual salary.

The CEO-COO relationship is the most important in the business. It requires deliberate fit, structured onboarding, and regular investment to sustain.

The biggest hiring mistake is choosing someone because they know how to do the job, not because they've actually done it.

The seven types of COO

1. Executor — gets things done when the CEO is overloaded or unfocused; execution-first role
2. Change agent — steers the company through a pivot or major directional shift
3. Mentor — has already built at scale; comes in to lead rather than be delegated to
4. Other half — interchangeable with the CEO; can represent the company in media, on stage, in board meetings
5. Partner — holds equity; sees the business through an ownership lens; requires separate partner and operational meeting rhythms
6. Heir apparent — known internally as the successor; transitioning into leadership over time
7. MVP — a key player who must be given the role or will leave; retention is the primary driver

Handcuffing A players

• Different people want different things: equity, phantom stock, profit sharing, visibility, autonomy, spin-off responsibility, an executive MBA
• Identify what matters to each person individually — one-size retention doesn't work
• If you don't handcuff your A players, competitors will poach them

Titles matter more than founders think

• Title inflation since the 1990s has distorted expectations; a director-level role with a CMO title creates salary pressure and misaligned expectations
• Match title to: compensation level, roles and responsibilities, strategic input, autonomy, and P&L ownership
• Start people at a lower title so they have something to grow into — promote based on metrics, leadership development, and expanded responsibility
• Giving out inflated titles early removes the carrot and inflates your cost base

Activity inventory: deciding what to delegate

• List every task you do; categorise each as Incompetent, Competent, Excellent, or Unique ability
• Assign an hourly rate to each task
• Remove everything below your effective hourly rate — or at minimum, below that rate divided by four
• An EA can cover a year or two of COO-level offloading at a fraction of the cost

Onboarding a senior hire: the 90-day rule

Month one — observe only:

• Sit in on every business area's meetings
• Get blind CC'd on all executive communication
• Have lunch/dinner with every people manager
• Read all manuals and watch training sessions
• Receive a full CEO brief on core values, BHAG, vivid vision, and company history
• Write every idea in a physical notebook — no action, no discussion, no decisions

Month two — test hypotheses:

• Go back to those 50+ ideas and pressure-test each one with the relevant people
• Identify which projects are foundational (unglamorous but load-bearing) vs. easy wins
• Sequence projects by impact and implementation cost

Month three — execute easy wins:

• Start with low-pain, high-leverage projects that produce lasting results
• Build team trust before tackling people decisions or large structural changes
• Only after this foundation is set should hiring, firing, and major changes begin

The CEO-COO relationship

• Treat it like a marriage — more important than any other executive pairing
• Create a private space or ritual for working together away from the team ("date night")
• The COO's public role: make the CEO look good externally, absorb the tough decisions
• The CEO's internal role: make the COO look good to the team
• Bring in a relationship coach early if styles clash — don't wait for problems to surface

The interview system

• If you need 90 days to know whether you hired right, the interview process failed
• Invest in proper interview training: role-play, video review, structured references
• Top executives are not on job boards — you must actively poach them
• Write job postings that make the opportunity compelling, not just the role

When the party ends

• A senior leader can typically survive two revenue doubles; the third double usually requires a replacement
• An alternative framing: one triple in revenue is the ceiling for most executives
• Plan this transition proactively — it is not a failure, it is a structural reality
• Two things extend a leader's runway: hiring someone who has already operated at scale, and investing heavily in their ongoing skill development
