The CEO mastermind: how it works and how to choose the right one

A mastermind is a small circle of CEOs who meet regularly to share strategies, challenge each other and speed up their results, led by an experienced mentor. Small-group sessions, hot seats, confidentiality and accountability are its pillars. To choose well: members at a comparable level, a seasoned mentor, a structured method, selectivity at entry, and a commitment over time.

A CEO's isolation: the problem nobody wants to name

There's a question I ask every CEO I meet: « Who do you actually talk to about your company? » The answer is almost always the same: silence, then an awkward smile.

You can't tell your staff everything. Share your doubts about cash or your strategic hesitations and you create anxiety in the team. You can't tell your partner everything: they love you, but they don't live your problems of hiring, margin or positioning, and your marriage deserves better than becoming your board. And your friends? Most of them are employees. When you mention the pressure of a payroll to meet every month, they tell you how lucky you are to be your own boss.

The result: you make decisions alone that commit your company, your assets and your people. With nobody to argue back, no mirror, nobody to say « careful, I've already made that mistake ».

The problem isn't new. In the 1930s Napoleon Hill studied the highest-performing business people of his time and found one common denominator: all of them leaned on a « mastermind », a collective brain of peers pooling their experience and energy in the service of each other's objectives. Nearly a century later the principle hasn't aged. It has simply become professional.

In this article I'll explain what a mastermind really is, how a session actually runs, what you can expect from it, and above all how to choose the right one. Because masterminds are far from equal.

What a mastermind really is (and what it isn't)

A mastermind is a small group, usually 8 to 25 CEOs, meeting at regular intervals with a single objective: moving each member's company forward through the collective intelligence of the group. Everyone brings their experience, their mistakes, their winning strategies, their outside view. And everyone leaves with clearer decisions and concrete commitments.

To understand the idea, it's easier to start with what a mastermind is not:

• It isn't a training course.In a course, an expert transmits content downward to a group that listens. In a mastermind, the content is you: your real situations, your real numbers, your real decisions. You don't come to learn a theory, you come to solve concrete problems with people who have already lived them.
• It isn't networking.A networking event exists to collect business cards and commercial opportunities. A mastermind generally forbids selling between members. You don't come to pitch, you come to be challenged. The network forms, but as a consequence of trust, not as the objective.
• It isn't group therapy.Yes, doubts and fears get discussed, sometimes very personal matters, because a CEO's life doesn't come in separate slices. But the purpose stays action: every session ends with decisions and measurable commitments, not with the simple relief of having talked.

The truest definition I know fits in one sentence: a mastermind is the board that most companies don't have. A circle of peers with no interest in flattering you, no reason to spare you, and one mission — that you make better decisions, faster.

How a mastermind session actually runs

The format varies between organisations, but a serious mastermind always rests on three things: a structured ritual, an absolute frame of confidentiality, and a commitment mechanism.

What a session looks like

A session runs from half a day to two days depending on the format. It opens with a round table: each member shares their results since the last session, where their previous commitments stand, and their main current challenge. That simple ritual changes everything: knowing you'll have to announce your numbers to your peers in six weeks transforms how you execute.

Then comes the heart of it: the hot seat. One member takes the chair and lays out a precise problem in ten to fifteen minutes — a key hire that's stuck, an investment decision, repositioning an offer, a dispute between partners. The others first ask clarifying questions, without giving advice. That discipline is essential: understand before you recommend. Then each shares their experience: « here's what I did in a similar situation, here's what happened ». The member on the hot seat closes by announcing their decision and their next actions.

The mentor running the session is decisive at that moment: they steer the exchange, push the questions the group doesn't dare ask, connect the situation to strategies they've seen work elsewhere, and make sure the member leaves with a plan rather than a list of contradictory advice.

Confidentiality, the condition for everything else

No hot seat works without total trust. That's why any serious mastermind imposes an absolute confidentiality rule, often written down: what's said in the circle stays in the circle. Numbers, difficulties, plans, personal situations. That guarantee is what lets a CEO say out loud « I'm thinking of parting with my business partner » or « my cash won't last six months » — sentences they have never said to anyone.

Commitment, the engine of execution

Finally, each session closes with individual commitments, dated and measurable, announced to the group. At the next session, everyone reports back. That accountability mechanism is probably the most underrated of all: it turns intentions into actions, week after week.

The 4 measurable benefits of a mastermind

Beyond the feeling of no longer being alone — real, but hard to quantify — a good mastermind produces four concrete effects on your company.

1. Faster, better-informed decisions

When you hesitate alone over a decision, you can circle for weeks. In a mastermind, you put the situation to ten or fifteen CEOs, several of whom have faced exactly the same dilemma. In an hour you collect years of accumulated experience: what worked, what failed, the traps invisible from where you stand. You don't decide in their place, but you decide with information you'd never have had alone. Decisions that took three months get made in three weeks.

2. The mirror on your blind spots

Every CEO has blind spots: the offer you keep out of attachment while it destroys your margin, the long-standing colleague you protect while they hold the team back, the price you daren't raise. Your team sometimes sees them, but won't tell you. Your peers have no reason to stay quiet. The outside view of people with nothing to lose by being honest with you is one of the most valuable assets there is. It's often uncomfortable. That's exactly why it works.

3. Accountability that forces execution

You already know what you should be doing in your company. The real question is: why aren't you doing it? Because nobody will ever ask you. A mastermind installs what your position took away: someone to answer to. Announcing an objective to fifteen peers you respect, knowing you'll have to present the result in six weeks, lifts your execution rate dramatically. This isn't negative pressure: it's the same mechanism that makes an athlete progress faster in a club than alone.

4. A high-level network, in depth

After a year of sessions, hot seats and seminars, the members of a mastermind know each other better than most business partners do. That level of trust naturally produces qualified introductions, partnerships, recommendations for proven suppliers, sometimes major business opportunities. The difference with ordinary networking? Here the relationships rest on months of mutual transparency, not on a conversation over drinks.

The 5 criteria for choosing the right mastermind

The word « mastermind » isn't protected. Anyone can gather ten people around a coffee and call it one. Before committing, run every programme through these five criteria.

1. Members at a comparable level

This is criterion number one, and it conditions all the others. You need peers at your revenue level or above. If you turn over €500K and half the group is barely starting, you'll be the one giving without receiving. Conversely, a group slightly above you pulls your standards up: your « ceiling » becomes their normal. Always ask for the profile of current members: revenue levels, sectors, years in business.

2. Led by an experienced mentor

There's a fundamental difference between a facilitator who hands out speaking turns and a mentor who has built and grown companies themselves. The first runs a conversation. The second spots the real problem behind the stated one, confronts the excuses, and brings proven strategies when the group reaches its limits. The mentor also sets the standard of the circle: without one, even a good group drifts gently into pleasant conversation.

3. A structured framework and method

A serious mastermind rests on a process: the format of hot seats, preparation required before each session, follow-up on commitments, a thematic progression across the year. Ask to see what a typical session looks like and the annual calendar. If the answer is vague, the programme runs on improvisation. And improvisation doesn't survive twelve months of sessions.

4. Selectivity at entry

A mastermind that accepts everyone isn't one. The selection process — application, interview, revenue criteria, mindset — protects the quality of the circle: it's what guarantees each member gives as much as they get, and that confidentiality will hold. Be wary of programmes where the only admission criterion is a credit card.

5. Commitment over time

The trust that makes hot seats powerful is built over months. A member who comes to « try » a session, or a group that turns over entirely every quarter, will never produce that depth. Favour formats with a minimum annual commitment and a regular rhythm of sessions. It's also a signal about the other members: people who commit for a year are there to work, not to sample.

The traps to avoid before you commit

Three pitfalls come up systematically with CEOs disappointed by a first mastermind.

The group that's too mixed.This is the most common trap. A circle mixing €50K and €5M companies doesn't work: the problems have nothing in common, the more advanced get bored, the others feel crushed. The advice turns generic because it has to speak to everyone. You leave the sessions feeling you had a good time, without a single actionable decision.

The circle of comfort.When a group puts comfort before truth, it becomes a mutual encouragement club: everyone validates everyone else's choices, nobody asks the uncomfortable question. It's pleasant, and perfectly useless. The tell: if nobody has contradicted you in three sessions, you're not in a mastermind, you're in a tea room. Demanding support is the culture the mentor has to install and defend.

The absence of method.Pleasant gatherings, with no structured hot seat, no follow-up on commitments, no thread through the year, produce conversations, not results. After six months the serious members leave, and only the sociable ones remain. Check the method before you sign, not after.

Mastermind and the 9 levers: why the collective is the GROWTH lever

Among the 9 levers, the ninth is GROWTH: the multiplier, the one that turns clients into advocates and a company that's progressing into a company that's accelerating. And there's a precise reason that lever runs through the collective.

The first eight levers (vision, strategy, offer, sales, profit, systems, team…) can be worked on alone. But each one progresses at the speed of your own experience. In a circle of peers, strategies circulate: the member who doubled their margin by repricing passes the approach to the one stuck on that lever; the one who built a leadership team saves two years for the one hiring their first second-in-command. Every individual win becomes a collective shortcut. It's arithmetic: fifteen CEOs sharing their strategies honestly progress faster than fifteen isolated CEOs, however brilliant.

That's exactly what led me to create MaxMasterMind in 2016: a circle for CEOs from €100K of revenue upward, with privileged access to my own work, exclusive seminars and individual mentoring between sessions. Ten years on it's still the programme I'm proudest of, precisely because the results come as much from the members as from me. If you want to see how it fits with the other programmes, it's all set out onthe programme pages.

But whether you join MaxMasterMind or another circle, the essential message is the same: don't stay alone. Strategic isolation is a handicap you can lift with one decision.

Sceptical at the start: Audrey's story, a pharmacist

Audrey had just bought her pharmacy, around €1.5 million of historic revenue, and the start was hard: numbers below expectations, margin at zero, daily stress. Her first reaction to Max's videos, in her own words: « it's a bit odd, it looks like a sort of cult, some American-style guru ». What convinced her was checking the testimonials and finding CEOs from her own sector, healthcare: peers she could verify, not promises.

« I got fed up with being fed up. I told myself: I'm no worse than anyone else, I should be able to do this. I need to find help. »

A few months later, the outcome: her first real margin since taking over. That's exactly what a well-chosen collective produces — peers at your level, a framework that forces execution, and proof you can check before committing.

Frequently asked questions

What does a CEO mastermind cost?

Prices vary widely: from a few thousand euros a year for a local group run by a facilitator, to several tens of thousands for a high-end mastermind including individual mentoring and seminars. Think in terms of return: a single strategic decision accelerated, or one mistake avoided, often covers the annual investment.

What's the difference between a mastermind and one-to-one mentoring?

One-to-one mentoring gives you the exclusive attention of a mentor who tailors every piece of advice to your situation. A mastermind adds collective intelligence: peers who have lived your problems, challenge you without flattery and open their network to you. The two complement each other: the best programmes combine group sessions with individual support.

At what stage should I join a mastermind?

A mastermind becomes relevant once your company generates stable revenue, generally from €100,000 a year, and you're looking to break through to the next level. Below that, structured training builds your foundations more effectively. Above it, the peer effect becomes the fastest lever you have.

How much time does a mastermind take?

Allow one to two days a month across the group sessions, exchanges between peers and implementation. That's precisely what makes it work: a CEO who blocks a day a month to work on the company rather than in it makes better decisions the rest of the time.

What's the difference between a mastermind and a training course?

A course delivers identical content to everyone, then each person leaves alone. A mastermind works on your real situations, with the experience of peers facing the same stakes, and a group accountability that forces execution. Training brings knowledge; a mastermind brings action.

What to take away

A mastermind is neither a training course, nor networking, nor a discussion club. It's a growth instrument in its own right: a small circle of selected peers, a mentor who sets the standard, confidential hot seats, and accountability that forces execution. Chosen well, it gives you what neither your team nor the people around you can: the truth, lived experience, and the momentum of a group aiming higher than you.

So ask yourself, honestly, the question I opened with: who do you actually talk to about your company? If the answer is « nobody », you now know what to do. Assess the circles that exist against the five criteria in this article, insist on meeting the mentor and knowing the members' profiles, and commit for the long run. Your next stage of growth won't happen alone.
