For many Principals, the idea of running a Single Family Office (SFO) carries a certain irresistible glamour. It is private, it is bespoke, and it is dedicated entirely to the needs, ambitions and values of one family. In an SFO, every process, every hire, every investment mandate exists solely to serve you and your chosen legacy. There is no need to compromise with other stakeholders, no competing agendas, and no limit on how far into the future you can plan.
But the truth is that just because you can have a family office, it does not mean you should. The choice between an SFO, a Multi-Family Office (MFO), a hybrid model or a Virtual Family Office (VFO) is not simply a question of “how much do we have to invest?” It is also a question of scale, governance, culture, human capital, and perhaps most underestimated of all, the Principal’s own appetite for and capability to run what is, in reality, a highly complex professional services firm.
The SFO: bespoke control, but at a price
An SFO is the Savile Row suit of wealth management. Every detail is tailored to fit; from the investment guidelines to the succession plan, from the philanthropic strategy to the reporting cadence. For families who value privacy and control above all else, it is hard to beat. An SFO can look far beyond quarterly returns, shaping strategies for children yet to be born, and ensuring alignment between every professional in the office and the Principal’s objectives.
However, this level of customisation is only sustainable at sufficient scale. In practice, our experience suggests that at least $750 million in assets under management is needed before the economics of an SFO begin to really work. Below that threshold, it becomes difficult to retain top talent, justify full-time specialist roles, or access the most attractive direct deals and co-investment opportunities. Even at higher levels of wealth, SFOs carry a concentration of human capital risk: a small team means that one maternity leave, one resignation, or one extended illness can leave vital functions uncovered. And as the years go by, without variety or fresh challenge, even the most capable professionals can become stale.
When things go wrong, the supposed freedom of running your own office can feel surprisingly like running a business again. Principals who imagined they had stepped away from operational burdens can find themselves back in an executive chairman’s role, dealing with everything from compliance headaches to a burst pipe in the office.
The MFO: scale, reach and a different kind of culture
If an SFO is a bespoke suit, an MFO is high-quality custom clothing. It may not fit with the same perfection, but it offers excellent value and in many cases, a broader range of capability. Because MFOs serve several families, they can assemble deeper pools of financial and human capital, attract specialists across multiple disciplines, and spread the cost of sophisticated infrastructure.
This scale also reduces key person risk. In an MFO, the loss of one professional does not disrupt the entire operation. It also creates a subtly different culture. Professionals in an MFO are less beholden to one individual’s favour; they can “speak truth to power” without fearing for their job in the same way as an SFO employee with a single employer. Many Principals find this healthy and refreshing.
Of course, there are compromises. You share control over investment philosophy, and you may have to accept less transparency and customisation. The internal politics of an MFO can also be shaped by relative standing. If the founder family has a billion dollars under management and you arrive with a tenth of that, you may find yourself a price taker rather than a price setter. For some, this is a deal breaker; for others, the trade off is entirely worth it.
The hybrid model: control where it matters, scale where it counts
Increasingly, families are rejecting the binary choice between SFO and MFO, opting instead for hybrid structures. In a hybrid model, the family retains a lean in-house team to manage the most sensitive, family-specific functions,governance, philanthropy, operating businesses, and perhaps certain liquid portfolios,while outsourcing more specialist, capital-intensive or network-driven areas such as private equity, real estate, hedge funds and co-investments to an MFO or other external providers.
This approach allows the Principal to keep control and alignment where it matters most, while still benefiting from the reach, relationships and infrastructure that only scale can deliver. It also creates more flexibility to adjust the balance between in-house and outsourced functions as the family’s needs, complexity and generational profile evolve.
The virtual family office: a credible option at last
Until recently, the phrase “virtual family office” carried a faintly second-class ring. It suggested a budget version of the real thing, but today that perception is out of date. Technology has transformed what a virtual set-up can achieve. Secure cloud platforms, integrated reporting systems and encrypted communication tools allow professionals anywhere in the world to operate as an invisible extension of your team. Specialist providers now design their services for precisely this kind of arrangement, delivering best-in-class advice and execution on an as needed basis without the fixed costs of permanent staff.
In effect, a well-designed VFO can now combine the personalisation of an SFO with the breadth of an MFO, at a fraction of the overhead. It is not for everyone, and curation of providers is critical, but it has become a serious option for families at every level of wealth.
The service-by-service decision
Whichever structure you choose, there remains the question of what to keep in-house and what to outsource. The decision hinges on variables such as how niche the expertise is, how long you will need it, how sensitive the work is, and whether your office can realistically attract and retain the best talent in that field. In some areas,tax planning, complex reporting, due diligence,the infrastructure and experience of specialist firms are hard to replicate in-house without exorbitant cost.
Conversely, when control, alignment and context are paramount, such as with governance, succession planning or the management of a highly idiosyncratic family business, keeping the work in-house may make more sense. The right answer is rarely fixed. As family circumstances change, so should the balance between in-house, outsourced and technology enabled solutions.
The new reality for Principals
The old logic was simple, the more wealth you had, the more you needed to build internally, but that logic no longer holds. The combination of specialist MFOs, sophisticated outsourcing, hybrid structures and rapidly advancing technology means that SFOs are no longer the default for the ultra wealthy.
For some families, the independence, privacy and alignment of an SFO will always be worth the cost and complexity. For many others, there are now more flexible, less burdensome ways to achieve their goals. The best Principals continually reassess their arrangements, rebalancing the mix of in-house, outsourced and virtual services as their needs and ambitions evolve.
Because, in the end, just because you can have a family office, does not mean you should.
If you are weighing up the options, you need a clear-eyed understanding of the human and operational realities behind each model. That is exactly what Family Office Fundamentals: Human Capital Matters delivers, drawing on decades of experience from Mark Somers and the Somers Partnership and over fifty experts from across the family office ecosystem.
