Forum vs Peer Advisory Group vs Mastermind Group: How to Tell Which One You Need
A peer advisory group is usually a larger, professionally chaired room built around business problems; a mastermind is usually a smaller, self-organized group built around accountability, and a Forum is a small, facilitated group where personal matters are in scope alongside professional ones. These terms get used interchangeably across the executive development space, but they represent distinct practices with different origins.
A Forum is a small group of six to eight leaders who meet regularly, in confidence, with a trained facilitator, to work through the professional and personal challenges they are actually facing.
Disclosure: ForumSpace publishes this guide and operates facilitated Forums for senior leaders. To help you make an informed choice, this article explains the distinct mechanics of these three formats without ranking providers; readers looking for ranked options can review our guide to the best mastermind groups for leaders.
The Short Answer
Format | Typical Group Size | Who Leads It | What Is in Scope | Typical Cadence | How You Join |
Peer Advisory Group | 12 to 16 members | Paid professional Chair | Business strategy, operations, and leadership | Full day monthly | Application and vetting by the Chair |
Mastermind Group | 4 to 8 members | Self-managed or community host | Goal progress, accountability, and tactical advice | Weekly, bi-weekly, or monthly | Open enrollment, course attachment, or invitation |
Forum | 6 to 8 members | Trained facilitator | Both professional and personal challenges | Monthly virtual meetings with one annual in-person retreat | Nomination by a Sponsor or application via directory |
What a Peer Advisory Group Is
The term peer advisory group was popularised by Vistage, which built its model around large, professionally moderated cohorts of executives. In a peer advisory group, 12 to 16 non-competing business leaders gather for a structured, full-day meeting each month. The session is led by a paid professional Chair, often a former CEO or seasoned executive coach, who directs the agenda and keeps the conversation focused on operational and strategic growth.
These groups excel at delivering broad, cross-industry business insights. Because the room is larger, members gain access to a wide array of functional perspectives on issues like supply chain expansion, executive hiring, and capital allocation. Many peer advisory group models, including Vistage, pair these monthly group meetings with one-on-one coaching sessions between the member and the Chair to track individual execution. The scope remains firmly centered on business strategy and company performance.
What a Mastermind Group Is
A mastermind group is typically smaller than a peer advisory group and revolves around goal tracking and peer accountability. Unlike structured peer advisory models, mastermind is the least standardized term in leadership development. Two groups using the label might operate completely differently. One mastermind might be a self-organized gathering of three founders meeting weekly over video, while another is a paid feature attached to an industry community or digital course.
In most mastermind groups, meetings follow a hot seat format. One or two members present a specific operational goal or obstacle, and the remaining participants offer tactical advice, feedback, and shared contacts. Because masterminds are often self-facilitated or led by a community host rather than a trained professional, the quality of the group depends almost entirely on the commitment and discipline of the individual members. Their primary value lies in fast-paced accountability and targeted tactical advice.
What a Forum Is
Forum is a specific peer group methodology. Organizations like Entrepreneurs' Organization (EO) have operated Forums for decades, and ForumSpace is one of several organizations running the format today.
A Forum consists of six to eight people who meet regularly under strict confidentiality. Unlike standard business groups, a Forum explicitly brings both professional and personal matters into scope. Senior decision-makers face pressures that cannot be cleanly split between the office and home; a Forum provides a room where leaders can process the full weight of their roles.
The methodology relies on absolute predictability and a highly structured meeting sequence:
Settling exercise: A brief moment of silence or guided breathing to clear distractions and bring members fully into the room.
Opener: A quick, one-word or one-sentence check-in regarding each member's current state.
Clearing round: An opportunity to voice any urgent emotional or practical distractions before deep work begins.
Updates and deep dives: Structured presentations of real challenges, where members share lived experiences rather than unsolicited advice.
Our Forums are always led by a trained facilitator who ensures the group adheres to strict structure, protocol, and confidentiality.
The Differences
Understanding how these formats diverge in practice helps ensure you select the right environment for your leadership needs.
Leadership and Facilitation
Peer advisory groups are guided by an executive Chair whose role includes direct coaching and group facilitation. Masterminds are frequently self-led or moderated by a peer host without formal facilitation training. In a Forum, trained facilitators guide every session to maintain protocol, balance airtime, and enforce confidentiality without stepping into the role of a directive coach.
Scope of Discussion
Peer advisory groups keep the focus on business problems, scaling strategies, and commercial execution. Masterminds focus on progress toward personal or business goals. Forum is explicitly designed for the whole person, treating personal pressure, family dynamics, and executive isolation as equally valid subjects alongside commercial strategy.
Group Size and Composition
Peer advisory groups bring 12 to 16 leaders together to maximize the diversity of business experience in the room. Masterminds range from 4 to 8 members, though turnover can be high if the group lacks strong governance. Forum maintains a consistent, tight-knit group of six to eight leaders to build deep psychological safety and long-term trust.
Vetting and Entry Requirements
Peer advisory groups vet members primarily by company revenue, title, and team size. Masterminds often use open enrollment or course completion as their entry barrier. Forum vetting focuses on leadership weight, willingness to share openly, and a commitment to showing up consistently.
How ForumSpace Approaches This
ForumSpace delivers fully supported Forum experiences for senior leaders and decision-makers. We operate small, facilitated groups of six to eight people where professional and personal challenges are both in scope, protected by strict confidentiality. Members join either through nomination by their company or by applying directly to our network.
To support this experience, ForumSpace provides:
Trained facilitators who guide every meeting
Structured Forum methodology to maintain consistent meeting protocol
Onboarding education so members arrive prepared to participate
Custom-built technology designed to support scheduling and confidential member communication
Ongoing operational support, curated insights, and leadership resources
What distinguishes our approach is our focus on the whole person and our insistence on trained facilitation. By addressing the personal realities of leadership alongside strategic business issues, members get a level of counsel that traditional business groups rarely accommodate. Our Forums are always facilitated to protect group health and ensure equal participation.
We operate around two primary roles: the Sponsor, who is the company or senior executive nominating a leader, and the Forum Mate, who is the leader participating in the group. For leaders seeking alternative formats or independent groups, we maintain the Forum Finder directory to help executives locate options across the wider ecosystem.
Who It Suits
ForumSpace is designed for senior executives, founders, and decision-makers who want confidential, high-trust counsel from peers carrying comparable weight. It suits leaders ready to commit to regular attendance and open sharing.
Who It Does Not Suit
ForumSpace does not suit individuals seeking tactical industry tips, lead generation, transactional networking, or a single expert consultant. Those needing immediate tactical advice or goal tracking may find a mastermind or professional coaching better suited to their goals. Executives seeking other providers can explore options through our Forum Finder.
Limitations
Our groups are cross-industry rather than sector-specific, entry usually requires a nomination or thorough application, pricing is available on request rather than self-serve, and the format requires a consistent time commitment, including monthly virtual meetings and one annual in-person retreat.
Pricing is provided on request, and organizations frequently cover the investment on behalf of nominated leaders. To learn more or request a placement, visit Find a Forum.

FAQ
Is a mastermind the same as a peer advisory group?
No. A peer advisory group is usually a larger, professionally chaired room focused on broad business strategy and executive coaching. A mastermind group is typically smaller, focused on goal accountability and tactical advice, and often self-managed.
What is the difference between a Forum and a mastermind?
A mastermind focuses primarily on professional goals, tactical execution, and peer accountability. A Forum is a confidential, facilitated experience of six to eight leaders where both professional and personal challenges are explicitly in scope.
Which format is better for a CEO?
No single format is universally better; choice depends on current needs. CEOs looking for broad strategic advice often choose peer advisory groups, while those seeking a private space to address both leadership weight and personal realities choose a Forum.
How big should a peer group be?
Group size depends on the format's purpose. Peer advisory groups run larger, with 12 to 16 members, to maximize business diversity. Forums function best with six to eight members to maintain deep trust, tight focus, and confidentiality.
Are these groups confidential?
Peer advisory groups and masterminds generally operate under non-disclosure agreements regarding business operational data. Forums operate under absolute confidentiality rules covering both personal and professional disclosures.
Conclusion
Peer advisory groups offer broad business advice in larger rooms, masterminds deliver targeted accountability for specific goals, and Forums provide a confidential space for both professional and personal leadership challenges. Matching your current leadership needs to the right format ensures your time spent in peer learning yields real results.
