A single family office (SFO) is built for one family. A multi-family office (MFO) serves several unrelated families on a shared platform. The practical differences sit in cost, control, privacy, staffing and how services are delivered.
Families choose an SFO when they want exclusive staff, full confidentiality and a bespoke operating model, and can carry the fixed cost alone. They choose an MFO when they want institutional capability without funding a full office. Hybrids sit between the two: dedicated teams for core work, shared infrastructure for the rest.
This guide compares the models side by side so principals and family office teams can decide which structure fits.
How family offices are organised
A family office is a private entity that professionally manages the wealth and personal affairs of an ultra-high-net-worth family, typically across generations. Families then choose between a single family office dedicated to one family, or a multi-family office that serves several families under one platform. For a fuller definition of what a family office is and does, see our family office definition guide.
The key issue with the single family office model is its high fixed operating cost, which the family carries alone (see the cost range in the table below). The multi-family office model solves this by pooling resources and distributing operational costs among all its clients. This allows multi-family offices to capitalise on economies of scale and provide a more diverse, scalable, and uninterrupted range of services by allocating larger sums to acquire state-of-the-art infrastructure and develop the very best research and wealth experts that the industry has to offer.
A single family office vs a multi-family office: How they compare
| Dimension | Single family office | Multi-family office |
|---|---|---|
| Who it serves | One family | Several unrelated families |
| Control | Full: the family sets mandate, hiring and vendors | Shared: platform policies and shared staff |
| Cost | Family carries the full fixed base (often US$1m–US$5m+ a year) | Shared across clients; lower entry cost |
| Typical asset level | Often discussed from ~US$100m+ for a staffed office (ranges vary widely) | Lower tickets possible; depends on the MFO |
| Privacy | Highest | High, with shared operating environment |
| Services | Fully bespoke | Institutional menu; customisation within the platform |
| Staffing | Dedicated team | Shared specialists across families |
| Best for | Families that need exclusivity and can fund it | Families that want scale, specialists and lower fixed cost |
As the responsibility of family wealth shifts to the new generation, the inheritance is often divided into smaller, fractional interests to make the transition easier. This has made multi-family offices the preferred choice for this new generation of UHNWIs due to their lowered costs and the advisory nature of their employees that are far less likely to be influenced by family biases and legacy issues as compared to a single family office. For example, the new generation has a notably higher risk appetite and is likely to be more open to investment opportunities in the private equity/venture capital sector which was often shunned by the last generation.
Which model fits
Choose a single family office if exclusivity, confidentiality and a fully bespoke team matter more than cost, and the family can sustain the fixed operating base.
Choose a multi-family office if you want broad specialist coverage and institutional infrastructure without building an office from scratch.
Choose a hybrid or multi-single model if you want dedicated control on core work while pooling technology, research or selected services.

Hybrids and multi-single offices
Hybrid or multi-single family offices are becoming an increasingly common occurrence as modern single family offices transition to a multi-family office model. As their name suggests, multi-single family offices are a consortium of single-family offices where certain services are handled by a multi-family office rather than being outsourced. This trend is also influenced by landmark regulatory changes in tax laws that have made it favourable for single family offices to work in conjunction with multi-family offices in a capacity that simply wasn’t feasible before.
How can single family offices retain their position in the market?
Despite the rapid growth of multi-family offices in the last decade, it is important to note that single family offices are still the preferred choice for many of the world’s ultra-wealthy. The reason? They offer a far more controlled environment for personalised wealth management with a level of confidentiality and exclusivity that often cannot be matched by multi-family offices. However, there are some critical focus points that single family offices must consider moving forward to ensure that they don’t fall behind during this turning point in the private wealth management industry.
- Adapting to a changing regulatory landscape – Geopolitical uncertainty has prompted many jurisdictions to make changes to their tax policies. This means that single family offices must be agile in adapting to these new policies without compromising their revenues and operational standards as expected from their clients and stakeholders.
- The age of technology and digital transformation – Disruptive technology solutions have a huge impact on the modern global economy and digital transformation has become one of the most formidable disruptive forces in the market. This creates numerous opportunities in the private wealth management sector. Modern single family offices must realise this and adopt a “digital-first” strategy for their operations, be it AI-powered automation for risk management or implementing superior cybersecurity solutions.
- Maintaining the risk-reward balance – Despite being one of the most fundamental operations of a family office, many single family offices still lack organised risk management frameworks. It is also important to note that “risk” includes both financial and reputational risks for the ultra-wealthy. Hence, it is vital that institutional-grade risk management norms are adopted by single family offices in a way that is tailored to the risk appetite of their clients.
