How to Build an Advisory Board for a Private Company: The Charter Template, a Four Way Comparison and the CEO's Board Map

By Andreas Pettersson, Founder, Leaders ADAPT

I hate a board that tells me what to do when nobody on it has been inside a business for years. Most CEOs I say it to don't argue; they say a version of it back. Maybe you have that board. Or you have none, and the loneliest decisions in a $30M company get made at a kitchen table.

An advisory board is a group of outside experts a company's owner or CEO appoints to give counsel on strategy, growth and risk, with no legal authority and no fiduciary duty, unlike a board of directors. It fixes both problems if you build it on purpose, and the 12 item Board Readiness Self Assessment, written for executives who want a seat, works in reverse: score the people you're about to give one.

The 2025 Compensation Advisory Partners survey of 633 private companies puts the median board at 7 directors, about half independent. You don't need seven. You need the right five, a one page charter, and the discipline to let them make you uncomfortable. This page is how to build an advisory board for a private company.

What is an advisory board?

A board of advisors is counsel you choose, on terms you write. Its members have no vote, no power to hire or fire the CEO, no duty to shareholders. What they have is experience you don't, and a standing appointment to apply it to your business a few times a year.

That lack of power is the point. A board of directors has to protect the company from its CEO. An advisory board exists to make its CEO better. The two coexist in many PE backed companies: a fiduciary board set by the sponsor, an advisory group the CEO builds.

Two things it is not. It isn't a personal board of directors, the mentors you call one at a time, who never argue in front of you. And it isn't a CEO peer group, where the other members run their own companies and you're one voice among twelve.

What is the difference between an advisory board and a board of directors?

Read the authority row twice. Advisory board vs board of directors isn't about quality. It's about who can remove you. Everything else here follows from that.

How do you build an advisory board for a private company?

Seven steps, in an order that matters more than the speed.

1. Name the job before the people. Write down the three decisions you got wrong in the last two years because nobody in the room had done it before. That list is the board's job. If you can't write it, you need a CEO advisor, not a board.

2. Write the charter. One page, below. It takes an afternoon and prevents the two failures I see most: a board that drifts into managing the company, and one that becomes a dinner club.

3. Recruit for the gaps, not the names. Map what your leadership team can't do, then find one independent advisor per gap. In our coaching data on what CEOs bring to coaching, owner CEOs (n=84) raised cash and pricing 57 percent of the time, hiring and team performance 55, sales growth 55, strategy 50 and AI 46. Most owner boards need a seat for each of the first three and one for whichever of the last two keeps you up.

4. Interview on wiring. What someone has done tells you less than how they think when they disagree with the room. Ask every candidate about the last time they told a CEO he was wrong. Don't fall in love with the first good one.

5. Retain legal control. The board is advisory, not operational. I've watched a founder set up a board with the power to fire him, in a company he owned. Yours advises. The charter says so.

6. Budget for insurance before the ask. Experienced people won't say yes without board liability coverage in place, roughly $2,000 a year (est., my own practice). The full compensation picture is on paid board positions.

7. Run the first meeting on one decision. Not a company overview: one live decision with a pre-read, three options and your recommendation. A board that produces a decision in its first meeting keeps showing up. One that gets a tour doesn't.

One owner I coach runs a company doing about $70M and wants five board members seated by 2028. Today the de facto board is one relative whose opinions swing. My advice: a board that counterbalances that energy with diverse experience and backgrounds, after a nine to twelve month cleanup inside the company, so the board arrives to a business worth advising.

The Board Charter template

A board charter is a one page document that states what the board is for, who sits on it, what it advises on, what it does not decide, how often it meets, how members are paid and how they leave. Seven headings, one paragraph each:

1. Purpose. The three decisions this board exists to improve, in plain words.
2. Authority. "This board advises. The owner decides." Name what the board never touches: hiring and firing, compensation, capital, the sale of the company.
3. Composition. Number of seats, the competence each seat covers, the independence rule (no customers, no vendors, no relatives).
4. Cadence. Meetings per year, length, the pre-read deadline (72 hours before), who attends from management.
5. Compensation. Per meeting fee, retainer or equity, expenses, insurance.
6. Conduct. Confidentiality, conflicts of interest, the expectation that disagreement is the job.
7. Term and exit. Two year terms, renewable once; either side can end it with 30 days notice and no explanation.

Hand it to every candidate before the first conversation. Anyone who argues with heading 2 is out.

How many members should an advisory board have and who should sit on it?

Three to seven. Fewer than three and you have advisors, not a board; more than seven and the quiet ones stop talking. No survey I trust measures it, so that range is my practice.

Who sits there is the harder question. It's not about age, it's diversity of thought, diversity of experience. Your superpower is to accumulate other people's superpower. A board of five 65 year olds in a 2021 cash crisis would never have said grind it out on sales and marketing, and the company I'm thinking of would not exist today.

Take a mix of high IQ and high EQ rather than one deep specialist. Then add the seat most owner boards are missing: in Deloitte's 2025 Global Boardroom Program survey of 695 board members and executives across 56 countries, 66 percent said their boards had limited to no knowledge or experience with AI, per Deloitte. I ran AI in production before ChatGPT existed and I still want someone at the table who deployed it in a business my size this year; AI for boardrooms covers what that seat should know.

Last rule: look for people who will stand their ground. Silent, agreeable members are decoration, not governance. Executives climbing the Board Path ladder toward a first seat are often your best candidates: they still operate.

How do you compensate advisory board members?

Less than directors, in a form that matches the stage. Advisory board compensation at private companies typically runs 65 to 75 percent of what the same company pays its fiduciary directors, per Compensation Advisory Partners (2025). Per meeting fees are the most common arrangement, then retainers, then equity at startups, and a real share is pro bono, per the Advisory Board Centre's 2022 to 2023 Advisor Engagement and Rates Report.

For an owner who can't pay cash yet, the play I give is to recruit experienced people late in their careers who want the board title and offer advisory equity that vests on milestones. For an owner who can, a per meeting fee keeps everyone honest: paid to show up prepared, not to be your friend.

How often should an advisory board meet?

Four to six times a year, two to four hours each, with a pre-read 72 hours ahead; most businesses with one land in that range, per the Advisory Board Centre. Quarterly is the floor. Monthly turns advisors into managers.

The cadence matters less than what fills it. Don't explain weak numbers live, because a board reads explanation as excuse. Put the numbers in the pre-read with your read of them, and spend the room on the one decision where their experience beats yours. A meeting that ends without a decision and an owner was a nice lunch.

How do you manage a board as a CEO?

This is the ask I get from executives almost every time, and the reason this page sits in our C-suite coaching hub: how a CEO thinks, or how to manage up and manage a board. I spent ten years as a tech CEO reporting to a board, and I became one of Canon's youngest CEOs inside that structure. Here's what I teach.

Map the room. Everyone above you is a supporter, a leaning supporter, a leaning terrorist or a terrorist. Never spend energy on the terrorists or the supporters, because they've chosen; work the leaning supporters, who pull the leaning terrorists over. It sounds political; it's stakeholder management, and it's how to manage a board of directors without losing a year to one member.

Assume two motives. There will always be a personal motive and a public motive. Find the personal one before you argue with the public one.

Shrink the hard meetings. For a difficult conversation, get as few people in the room as possible, ideally the two principals, with everyone else on standby to be called in for twenty minutes. You don't want your team to witness the emotional distress of that conversation, or a director performing for an audience.

Decide before you present. Post the job ad before the board meeting. Come to the board, show the growth, show how your close cycles shortened, and show you've already decided to staff up, which signals belief in where you're going. Boards back CEOs who decide; they manage CEOs who ask.

Keep the chair close. A hired CEO's job is largely the quarterly cycle: show progress, manage the chair, surprise nobody. An owner with advisors has the easier version: the chair is you.

What is a healthy CEO and board relationship?

One where the truth is cheaper than the pretense. The unhealthy version has one word: artifice. People pretend and bend to get along, the CEO gets surprised by his team, and the board gets surprised by the CEO.

A healthy CEO board relationship inverts that. The board hears bad news first and from you. Members disagree with you in the room and back you outside it, and at least once a year someone makes the room uncomfortable and is invited back because of it. The CEO leaves every meeting with one decision made better than he'd have made it alone, which is the only reason to have a board at all.

Advisory board FAQ

What is an advisory board?

An advisory board is a group of outside experts appointed by a company's owner or CEO to provide counsel on strategy, growth, risk and competences the leadership team lacks. Its members have no legal authority, no vote and no fiduciary duty to shareholders, which distinguishes it from a board of directors. They are common at owner led and private equity backed companies and are typically paid a per meeting fee, a retainer or equity.

What is the difference between an advisory board and a board of directors?

A board of directors holds legal authority: it hires, evaluates and can remove the CEO, approves major capital decisions and owes fiduciary duty to shareholders. An advisory board holds no authority and no fiduciary duty; it gives counsel the CEO can accept or ignore. Directors are chosen by shareholders or sponsors under the bylaws, while advisors are chosen by the owner or CEO. Many private companies run both.

How many members should an advisory board have?

Three to seven members is the practitioner range most owner led companies use; no major survey measures advisory board size directly. For comparison, the 2025 Compensation Advisory Partners survey of 633 private companies found a median board of directors of 7, about half independent. Each seat should cover a competence the leadership team lacks, such as pricing, sales, hiring, capital or AI, and members should not be customers, vendors or relatives.

How are advisory board members compensated?

Advisory board compensation at private companies typically runs 65 to 75 percent of what the same company pays its fiduciary directors, according to Compensation Advisory Partners (2025). In the Advisory Board Centre's 2022 to 2023 Advisor Engagement and Rates Report, a per meeting fee was the most common form, ahead of annual retainers, startup equity and pro bono service with expenses covered. Early stage companies often offer milestone based advisory equity instead of cash.

How often should an advisory board meet?

Most businesses with an advisory board hold four to six half or full day meetings a year, according to the Advisory Board Centre's 2022 to 2023 Advisor Engagement and Rates Report. Quarterly is the practical minimum for advisors to stay current with the business, while monthly meetings tend to pull advisors into operating decisions. Effective meetings use a pre-read sent several days ahead and focus on one or two live decisions.

How do you manage a board of directors as a CEO?

CEOs manage a board by controlling information flow and reading the room: send a pre-read with the numbers and the CEO's interpretation before every meeting, bring decisions already made with the evidence behind them, meet the chair between meetings, and identify which directors support, lean toward, lean against or oppose a direction so effort goes to the persuadable middle. Boards respond to CEOs who surprise them rarely and deliver bad news first.

The board you build is the room you'll have to sit in

Here's the test for every name on your candidate list. Picture the worst quarter of the next three years. Would this person say the thing you don't want to hear, and would you still want them at the table the quarter after? Yes to both, offer the seat; yes to one, you're building a dinner club or a firing squad.

I don't sit on boards and don't want to. But I know the value of a good one, because the most expensive mistake of my CEO years, saying yes to 47 priorities at once, was caught by a director, not by me. Build the room that would have caught it a year earlier.
