The Standard
The framework for how a Lean Family Office is governed, recorded, and kept true — published, consistent, applied the same way every time.
The Lean family office standard
You are the family office. That's the problem.
Circle 26 is the professional home for Lean Family Offices — the standard, the method, and the peer circle for the people who run complex family wealth without an institution behind them. Principals, operators, and the family member who inherited the job.
The problem
Who actually runs your family office?
At some point wealth stops being a financial question and becomes a coordination problem. Several entities. More than one jurisdiction. A web of advisors, each managing their slice. The advice is handled. What isn't handled is the whole — and the whole lives in one person's head.
Sometimes that person is the principal. Sometimes a chief of staff, a family office manager, or the family member who inherited the job. Whoever it is, they hold the full picture from memory, with no standard to work to, no peers who understand the role, and no way to know if they're doing it well.
The families with the most at stake often have the least structure behind them — and the person holding it together has no professional home. Until now.
What it is
What is Circle 26?
Circle 26 is the professional home for Lean Family Offices. We set the standard for how these offices are run, and equip our members to run them: the Lean Family Office Blueprint™, a working operating system, a facilitated assessment of where the office actually stands, and a peer circle of people doing the same job.
The Method
The Blueprint: 18 steps, five pillars, 70+ templates, and a working operating system for the office. Artefacts, not theory.
The Peer Circle
A capped peer circle of people running family offices — Monthly Sessions, Chatham House Rule, no commercial agendas.
Who it's for
Who is Circle 26 for?
The Principal
“I am the family office. That's the problem.”
You built the wealth and you run the coordination — from memory, between everything else. It works, and nobody could take over.
See the Principal page →The Operator
“I do the coordination. Nobody else knows what that means.”
Chief of staff, family office manager, director, or CEO — whatever your official role, you hold the whole picture for one family, with no standard, no benchmark, and no peer who understands the job.

The same standard, at a fraction of the cost.

Most families cross the complexity line long before they cross a wealth threshold.

What a Family Office Really Costs in 2026
A staffed family office averages ~$3M a year to run, 60–70% of it personnel, ranging from $1M to $10M. What drives the cost — and how a lean model changes it.
When a Single Family Office Is Actually the Right Answer
A single-family office is right above ~$250–500M in assets or with operating-business complexity. When it genuinely fits — and its honest downsides.
Can You Trust AI With Your Family's Private Information?
You can use AI with private family data safely — but only under the right terms. Consumer tools often train on inputs; enterprise ones typically don't. The safe rules.

Questions
Common questions
Is Circle 26 a multi-family office?
No. Circle 26 does not manage assets, take custody, sell products, or charge on assets. We set the standard for how Lean Family Offices are run and equip the people who run them. Your advisors stay yours.
Who counts as a Lean Family Office?
Any family running real complexity — multiple entities, more than one jurisdiction, a bench of advisors — without a large staffed institution. Typically two or three people, sometimes just the principal. The trigger is complexity, not capital.
What does membership cost?
Membership is one fixed annual fee per family office, covering three seats, with the facilitated Wealth Clarity Session included in year one. It is never linked to your assets. We confirm the figure at application — take the assessment first, and if membership isn't right for you yet, we'll say so. If you have already paid for a Wealth Clarity Session, that fee is credited in full against your first year's membership. You never pay for the session twice, and the total is the same whichever order you do it in.
Do you run the office for us?
No — and that's the point. We keep the standard; your people run the office. For families with nobody to fill the role, we offer a build service, deliberately limited to a few engagements a year.
Five minutes. An honest verdict.
