Both words get used for any group of business owners who meet on a schedule, which is why founders comparing the two get nowhere. Peer advisory is a defined format with organizations behind it that hold members to a standard. Mastermind is a label anybody can use, and in this market it covers several different products.
Where this comes from, so you can weigh it. I chair CEO peer boards in Miami and select the members myself, so everything below about the facilitated format is how I run it and how the organizations behind it define it. What I say about masterminds comes from two places: a review I did of the premium mastermind and peer-community market in August 2026 while designing a membership community of my own, and the groups founders describe to me when they arrive having already bought one. It is not a survey of every group that calls itself a mastermind, and it should be read for what it is.
My interest belongs before the argument rather than after it. I am paid to chair peer boards, and 305Founders is my own community, so I earn from a reader who applies and joins. This page argues for the facilitated format where it fits, and it sets out the cases where a mastermind is the better purchase, because for some of the founders who ask me this question it is.
What does “mastermind” mean?
Nobody owns the word and no certifying body stands behind it. In the groups I have looked at it covers four arrangements that differ on who does the work and on what the convener earns.
The teaching group. Built around one person’s method. The convener presents, and members take what they heard back to their own companies. What you are buying is that person’s approach and the discipline of returning to report on it.
The curated large group. Every member is expected to contribute, and the value is the aggregate of what the membership knows. These run bigger, and the format usually gives each member a slot to teach rather than a slot to be questioned.
The informal peer group. Organized by the members themselves, meeting without a facilitator, running on goodwill and on whoever takes responsibility for the calendar. These can work well and cost nothing beyond the time.
The program layer. The group sits on top of a coaching or training product and is included with it. The sessions are held and the content can be good. What you are buying is attached to the other purchase, so the group continues while that purchase does.
Those four are sold under one word, so “a mastermind” and “a peer advisory group” are not two comparable things, which is why the comparison stalls. Work out which of the four you are being sold and the question becomes answerable. If what you are weighing is one-to-one paid help, what gets sold as business coaching covers that separately.
What does professionally facilitated peer advisory mean?
Five conditions define it. They are the ones the organizations behind the format hold their chairs to, and the ones I work to.
Members are owners or chief executives, in a group sized so that each member gets time on their own decision across the year, meeting on a fixed schedule set a year ahead. Entry is by application and interview, and payment on its own admits nobody. Members are screened so that no two of them compete, which removes the most common reason to hold something back. A trained chair facilitates, owns no equity in any member’s company and sells nothing into the membership. Confidentiality is a rule the chair enforces rather than an understanding the members extend to each other.
Where one of those is missing you are buying something else, whatever the group is called. Without vetting it is a paid network. Without a facilitator it is a self-organized group, which can work, on goodwill rather than on structure. Where the commercial separation goes, the meeting is a sales channel with an agenda attached.
Mastermind and peer advisory group compared
The rows below are the dimensions that decide it. A website will not tell you where a particular group sits on any of them, and a direct question will.
| Dimension | Mastermind | Facilitated peer advisory |
|---|---|---|
| Who convenes it | A person or company whose own business is the group | An organization, through a chair trained to run the format |
| What the person running it earns from you | The fee, and in some arrangements a further product sold into the membership | A fee for facilitating, with no stake in your company; their own interest is in recruiting and keeping members |
| How members get in | Payment, in some cases against a stated threshold | Application and interview, with applicants declined |
| Who else is in the group | Decided by who bought, so competitors can be in it | Screened for comparable stage and for non-competition |
| Who runs the session | The convener, in the teaching arrangements presenting their own method | A trained facilitator working a protocol, so the group works your problem |
| What confidentiality means | An understanding among the people present | A rule the chair enforces, with a stated consequence |
| Continuity | Varies widely; membership can turn over between cycles | Fixed dates set a year ahead, with the same members across them |
| If the person running it leaves | Where the group was built around them, it ends with them | The organization replaces the chair and the group continues |
| What it does not do | Give impartial judgment on a decision the convener has a position in | Supply domain expertise, distribution, or a named method to copy |
How each format decides who gets in
The entry gate decides who ends up sitting next to you for the next year, and in the applications I take it is the thing candidates ask about last.
In the mastermind market I reviewed, entry turned on the ability to buy a place. Where a threshold was stated it was usually a threshold on spending rather than on the business, which tells you the other members can afford the fee and not much else about them.
Peer advisory gates on qualification and fit, and turns down applicants who could pay. I have declined founders who could have paid, for reasons that were about the group rather than about them: a competitor already in the membership, a stage too far from everyone else’s, or an owner who wanted a hearing rather than a challenge. The seat carries an opportunity cost, since the group has a fixed number of them.
That is the mechanic underneath the format. What a group refuses is what makes its membership worth joining, so ask any group who it has turned away and why.
Does it matter whether the other members compete with you?
It changes what gets said, which is most of what a founder is paying for.
On the boards I chair, non-competition is a screen rather than a preference. Two owners selling to the same buyers in the same market are unlikely to describe a pricing problem fully in front of each other, and neither of them is behaving badly. They are protecting a commercial position, which is what an owner should do. Non-competition does not remove every reason to hold back, since members can still share customers, suppliers, investors, or the same short list of people to hire. It removes the largest one.
Masterminds vary here, and some convene deliberately inside one industry. That is an advantage where the problem is a category problem: the same channel, the same regulators, the same seasonal pattern, the same short list of suppliers. The cost is that the members are also each other’s competitors, and the limit of the format is the decision a member would lose money by disclosing.
Stage is the same question in another form. Advice transfers more readily between companies of a comparable size and complexity. In the mixed groups I have seen, sessions tend to tilt toward whoever is furthest along, and the rest of the membership takes away a version of that person’s answer to a problem they do not have yet.
Whether the other members should share your industry at all is a separate decision from the one this page covers, and it turns on which of your questions need domain knowledge. Our guide to industry-specific and cross-industry peer groups sets out how to sort your own questions first.
When a mastermind is the right purchase
Four cases, and I would say so to a founder sitting across from me.
You want a specific person’s method. They teach it themselves, and you have looked at what they have built rather than at how they describe it. A group organized around one operator’s approach to a channel or a category is a direct way to get it.
The problem is a domain problem. Pricing inside one vertical, a distribution channel, a technical build, a regulatory change with a deadline on it. Generalist owners are the wrong people to ask, and a group convened around that domain is the right one.
You want reach. Introductions, distribution and access to a network are a legitimate purchase, and the facilitated format is built for something else. A founder whose main aim is who they meet should compare masterminds against founder communities and networking organizations rather than against peer advisory.
You are earlier than the qualification bar. Peer advisory organizations set a threshold on company size or on how long you have been running one. A founder below it is better served by a group that will take them now, and the facilitated format will still be there later.
There is a fifth case worth naming, because it costs nothing. Three or four owners you already trust, meeting monthly with the discipline to turn up and to give the time to whoever needs it most, will do a good part of what a paid group does. What it lacks is someone to hold the standard when the discussion goes soft, and any screen on who is in the group. Where the people are right, that matters less than the price of the alternatives suggests.
Where each format breaks down
Both have failure modes that surface after the money is paid, and few of them show up in a sales conversation.
On the mastermind side, three are worth checking for. Value concentrated in one person: where the group is the convener, it does not survive them losing interest, changing direction, or falling out with a partner, so ask what happens to the membership if that person stops running it. Membership tied to another purchase: where the group comes with a coaching or training product, the sessions tend to return to that product, and the group tends to end when the other purchase does. Growth that outruns vetting: a group admitting faster than it can screen dilutes its own membership, which is a problem for the people who joined because of who else was in it.
The peer advisory failures are different, and worth naming because an organization behind a format does not guarantee the format is being run properly. A qualification bar applied loosely: where the bar bends to fill a seat, comparability goes, and comparability is most of what the member is buying. A chair compensated mainly on recruitment: where the person running the group earns more for adding members than for the quality of the sessions, the incentive points away from the standard. A group selected for chemistry: a chair who admits on how well someone will get along with the others ends up with a comfortable membership, and comfort is the opposite of what a member is paying for. A membership that has converged: a long-standing group can settle into one shared view of how a company should be run, and a member running a different kind of business gets a consistent answer that does not fit.
What goes wrong inside a meeting, and how a member can tell whether their own membership is working, is covered in what a founder can expect from a peer group.
What to ask before paying for either
Seven questions. The answers separate the two formats faster than any description of them does.
- Who convenes this, and what else do they sell to members?
- How do people get in, and has anyone been declined?
- Who is in the group right now, by size of company and by industry?
- Is anyone in it a competitor of mine?
- Who runs the session, what training do they have, and do they hold any interest in a member’s business?
- What is the confidentiality rule, who enforces it, and what happens when it is broken?
- What happens to this group if the person running it leaves?
Then ask what access you get before committing. Some groups offer a guest session and some do not, and a refusal is not a bad sign on its own, since a confidential group has a reason to protect its members. What any group can give you is the written admission criteria, the facilitator’s conflicts and what they are paid on, what happens to the group if that person leaves, the attendance and renewal terms, and the names of current or former members who have agreed to speak to prospective ones.
Where this leaves the decision
Take the mastermind where you want a named person’s method, a single domain, or reach. Take peer advisory where the decisions in front of you are the ones only an owner makes, and there is nobody impartial to test them against. A founder who cannot say which of those two describes them is not ready to buy either, and the way to find out is to write down the decision that is costing them sleep.
Write down what you want out of it before you pay. Judge the group against that a year in, rather than against how the sessions felt.
Most founders asking this question want judgment they cannot get from anyone on their payroll. 305Founders convenes Miami owners who do that for each other, and it runs on the vetting and facilitation described above, which makes this our own offer and worth reading as such.
