Family Office Examples & Structures

How to Read These Examples

A family office is the organizational infrastructure a family builds around significant wealth. That infrastructure can look very different from one family to the next — shaped by asset complexity, family size, geographic reach, and how much the family wants to manage directly versus outsource. The three examples below are deliberately hypothetical. They are meant to show a range of possibilities, not a prescription for any particular family.

Each example includes an org-chart table and a brief narrative. Real offices rarely match any template exactly. Think of these as reference points on a spectrum, not boxes to fit into.

The Lean Family Office

Who This Fits

Imagine a founder who sold her logistics company and is managing a diversified but not yet enormous pool of capital. She wants oversight and coordination — a single point of accountability — but does not yet have the volume of transactions or complexity to justify a large internal team. This is a classic lean family office, sometimes called a micro family office.

The lean office typically employs two to four people internally and relies heavily on outside specialists for investment management, tax, legal, and estate work. The principal remains closely involved in decisions. The internal team's primary job is coordination, oversight, and making sure nothing falls through the cracks between advisors.

The lean structure keeps fixed costs low and preserves flexibility. The trade-off is that coordination depends heavily on one or two key internal people, which creates key-person risk — the danger that the office struggles if that central person leaves or is unavailable.

The Mid-Sized Family Office

Who This Fits

Consider a three-generation family with two operating businesses, a real estate portfolio, a collection of private equity fund interests, and a private foundation. The complexity of their affairs has grown past what a lean office can handle. They need dedicated investment oversight, a proper finance function, and someone managing the flow of information between departments. This is the territory of a mid-sized family office.

At this level, the office typically internalizes investment coordination and financial reporting while continuing to outsource highly specialized work — tax strategy, estate drafting, and certain technology functions. A Chief of Staff or Chief Operating Officer often serves as the connective tissue of the organization.

The mid-sized office is often the most organizationally complex relative to its size. It is large enough to require clear roles and internal processes, but not so large that it can afford deep bench depth in every function. Designing a sensible organizational structure from the outset saves significant friction later.

The Large Institutional Family Office

Who This Fits

Picture a multigenerational family with assets spread across public markets, private equity, direct operating investments, real estate in multiple countries, a private foundation, and a family governance program that includes a family council and a formal next-generation education curriculum. At this scale — think illustratively of a family with capital measured in the hundreds of millions or more — the office operates more like a small financial institution than a family support function. This is the institutional family office.

Every major function has dedicated internal staff. Outsourcing still exists — specialized legal work, certain investment strategies — but the office sets policy for everything and relies on vendors for execution, not judgment.

At this scale, the office itself becomes a meaningful employer and a small institution with its own culture, governance, and succession challenges. Succession planning applies not just to the family's wealth but to the leadership of the office itself.

What These Three Examples Show

Across all three structures, a few patterns hold. Investment management is present in every version, but it is never the whole story — tax coordination, legal entity maintenance, reporting, and family governance exist at every level of scale. The difference is whether those functions live inside the office or are managed through outside relationships.

The decision of what to internalize versus outsource — sometimes called the build vs. buy decision — is one of the most consequential choices a family makes when designing their office. Costs, control, and capability all shift depending on where the line is drawn. Families work with qualified attorneys and CPAs to understand how legal, tax, and regulatory considerations shape those choices in their specific circumstances.

There is no minimum asset level that automatically moves a family from one category to the next. A family with simpler holdings and low operational complexity may run a lean office comfortably at a scale where another family, with operating businesses or international assets, already needs a mid-sized team. The infrastructure should match the actual complexity, not a benchmark.

Building Your Own Structure

These examples are starting points. Families building an office from the ground up typically begin by defining purpose and inventorying assets before ever drawing an org chart. The series starting at How to Build a Family Office From the Ground Up walks through that process step by step, from defining the office's purpose to hiring the core team.
