The Real Difference Between an Interim CEO and a CEO Coach or Mentor
Many CEOs and investors ask where the line is drawn between a CEO Coach, a Mentor, and an Interim CEO. The distinction is more than semantics. Choosing the right type of support affects how quickly a business can stabilise, grow, or recover. This article unpacks the real difference, so you can decide whether your organisation needs reflection, action, or both.
“To build a strong team, you must see someone else’s strength as a complement to your weakness and not a threat to your position or authority.”
That quote captures the spirit of both roles. Each helps strengthen leadership in different ways — but the route and results are not the same.
The Role and Mandate
An Interim CEO steps into the top seat and assumes full operational and strategic control. Their remit is clear: stabilise performance, reset priorities, and lead the business through challenge or transition. They are often brought in after a CEO departure, during restructuring, or ahead of a sale or investment.
A CEO Coach or Mentor supports the existing CEO to develop and refine their leadership approach. They offer a confidential sounding board, challenge thinking, and bring perspective from experience. They do not lead the business; they help the leader lead better.
Authority and Action
The difference here is fundamental.
An Interim CEO carries delegated authority, typically from the board or investors. They are accountable for results, make executive decisions, and steer the business day to day.
A CEO Coach has no formal authority. Their influence comes from insight, trust, and perspective. They support reflection rather than action and are not responsible for business outcomes.
Timescale and Intensity
Interim CEO assignments are typically intense and time-bound. Engagements often last between three and twelve months. Objectives are clearly defined, and success is measured in commercial terms — stabilisation, cash flow improvement, or achievement of a milestone.
A CEO coaching or mentoring relationship unfolds over a longer horizon. It might last for years, with monthly or quarterly sessions, often off-site or over video. The value accumulates through steady, developmental progress rather than immediate turnaround.
Focus and Expertise
Interim CEOs are experienced operators with multiple leadership roles behind them. They thrive in complexity and ambiguity. They know how to read a P&L, reset a plan, and engage stakeholders under pressure. Their strength lies in execution.
CEO Coaches and Mentors bring a different lens. Many come from leadership development, psychology, or executive coaching backgrounds. Some have led businesses themselves, but their expertise is centred on behaviour, mindset, and interpersonal dynamics. Their strength lies in helping leaders reflect and adapt.
When a Coach Falls Short
There are moments when coaching alone is not enough. If a business is in crisis, performance has deteriorated, or investor confidence is slipping, a coach cannot take command. The business needs a leader — someone to act, decide, and be accountable. In the article When ceo coaching is not enough I write more about this.
This distinction becomes clear during operational stress or board-level breakdowns. In Chairing the Board When the Wheels Are Coming Off, I describe a real-world case where the priority was stabilising leadership, calming the board, and rebuilding direction. In that situation, an Interim CEO, not a coach, was the right answer.
Signs a Business Needs an Interim CEO
Common triggers include:
-
The unexpected departure or long-term absence of a CEO
-
A merger or acquisition requiring transitional leadership
-
Periods of underperformance needing decisive action
-
Investor pressure for accountability or delivery
-
A pre-sale phase where confidence depends on operational grip
In these scenarios, the business needs someone to lead immediately. This is not the time for subtle nudges or reflective development plans.
Where Coaches and Mentors Shine
Coaches and mentors are invaluable when:
-
A CEO is stepping up to a larger remit
-
The business is performing well but wants to go further
-
Emotional intelligence, communication, or decision-making need sharpening
-
The board is investing in leadership development or succession
-
The CEO is managing complex team dynamics
These are the times when reflection and personal growth pay dividends. In Chairing the Board When the Wheels Are Coming Off, I also touch on how leaders benefit from knowing when to pause and choose a calmer path — something coaching relationships support uniquely well.
Can These Roles Work Together?
Yes, and sometimes they should.
A business might appoint an Interim CEO during instability while arranging CEO coaching for executives preparing for the next phase. Equally, once a permanent CEO is appointed, ongoing coaching can ease their transition.
The key is clarity. Each role must have a defined mandate. Confusion over purpose can create friction and slow progress.
Common Misconceptions
“An Interim CEO is just a stopgap.”
Not true. A skilled interim leader does far more than hold the fort. They set direction, deliver results, and often leave the business stronger than they found it.
“Coaching is only for underperforming leaders.”
Quite the opposite. Many of the best CEOs actively seek coaching. It’s a sign of self-awareness, not weakness.
“We don’t need an Interim CEO — the team can hold the fort.”
In theory, perhaps. In practice, leadership vacuums create drift. Decisions stall. Accountability blurs. An interim leader restores focus and pace when it matters most.

A Final Thought
I’ve worked both as an Interim CEO and as a Strategic CEO Advisor (or coach). I’ve also witnessed what happens when the wrong type of support is chosen. The cost — in time, morale, and credibility — can be high. I explain more about an Executive Coaching Alternative here
This is not about semantics; it’s about strategic fit. One role leads. The other supports. If your business is unclear which it needs, start with one simple question:
Do we need advice, or do we need action?
If you’re reflecting on that question, you may find further insight in the From the Touchline leadership series — grounded reflections that explore the real dynamics behind leadership under pressure, whether that means stepping in, stepping back, or stepping up.
Frequently Asked Questions
What does a CEO Coach actually do?
A CEO Coach works as a confidential thinking partner, helping leaders clarify strategy, improve decision-making, and strengthen team alignment without taking operational control.
When should a business appoint an Interim CEO instead of a Coach?
When immediate leadership and accountability are needed — such as crisis management, underperformance, or leadership transition.
Can a CEO have both a Coach and an Interim CEO?
Yes. It’s often the most effective structure during change: one drives execution, the other builds long-term leadership capacity.
How do I choose the right type of support?
Start by defining what the business needs most — stability and action, or reflection and development. The right choice depends on timing and context.
