By Jacob Gamble, Principal — Jacob Gamble leads executive searches in investment banking, family offices, and asset management. His analysis has been featured in Fortune, Financial Times, Bloomberg Wealth, Business Insider, and other leading publications, delivering valuable insights on legacy preservation, aggressive growth, family offices, and topics at the intersection of investment, institutional strategy, and sustainable growth.
Every few years, the wealth industry rediscovers a product, dresses it up, and sells it back to families as a revelation. The latest is the family office. The brochures are glossy. The language is elevated, “architecting a lasting legacy,” “from vision to structure,” and underneath the poetry sits a real trend worth understanding and a sales pitch worth seeing through.
I’ve spent more than two decades in these environments, as an investor, an operator, a public company CEO, and now as an advisor to families on the leaders they put in charge. So let me separate the signal from the noise.
The signal is real. The number of single-family offices worldwide reached roughly 8,030 in 2024, up 31% in five years, and forecasters anticipate it to reach 10,720 by 2030. That growth isn’t manufactured; it tracks the biggest accumulation of wealth at the top since the Gilded Age and a fully anticipated generational handoff of trillions now leaving the boomers’ hands. When that much money moves, structure follows. So far, so good.
Here’s where the noise begins.
A family office gets sold as something exotic, almost a status object. It isn’t. Strip away the mystique, and it’s a dedicated structure for running a family’s finances, investments, taxes, estate planning, reporting, and governance. Useful. Often necessary. But the mystique is marketing, and it’s what gets families to overbuild.
And overbuilding is the actual risk, the one the brochures won’t lead with. The danger for a wealthy family is rarely that they fail to build enough. It’s that they build too much. A full internal team, the infrastructure to match, the whole apparatus, for a situation that never required it.
Then there’s the question the marketing is engineered to answer in one direction: in-house, outsource, or hybrid?
The hybrid model, which keeps the big decisions in-house and rents the back office, genuinely fits most families, and the data behind it is sound. But notice that the firms publishing these papers happen to sell the outsourced and hybrid pieces. That doesn’t make the advice wrong. It just means you’re reading a menu, not a neutral analysis, and the chef has a favorite dish.
Now, the part the brochures gloss over.
Every one of these papers names “key-person risk,” the polite phrase for “a single point of failure,” what happens when one critical employee walks out and takes the institutional memory with them. They name it as a reason to outsource to them.
But you can’t actually outsource your way out of it. In-house, hybrid, fully delegated, doesn’t matter. The enterprise still rests on a small number of people. A Chief Investment Officer. A CFO. A Chief of Staff, sometimes a non-family CEO. Those seats aren’t plumbing. They’re the whole house. A family office with a mediocre CIO and a beautiful operating model is just a beautiful operating model losing money.
Let me give you a real example of what this looks like in practice.
A Forbes 400 single-family office in New York approached us to fill a CFO role. This was not a family that lacked structure. They were a lean, sophisticated team, the principal running point as CIO, a portfolio heavy in private holdings, and planning a move toward liquidity. On paper, a finance hire. In reality, the job was to find someone who could run the finance engine and sit across the table from the principal as a genuine thought partner on risk, governance, and allocation. Someone who would push back when the principal was wrong.
Here’s what mattered in that search, and what doesn’t show up in any operating-model diagram: the technical bar was the easy part. Plenty of people can run treasury and reporting for a multi-entity portfolio. The hard filter was temperament.
The family wanted humility, candor, and discretion. Someone who could act as a respectful counterpoint without ego, in a low-key environment where trust gets built over years, not quarters. We screened against that as rigorously as we screened the résumé. We ran confidential outreach without naming the family. The placement took months, most of it spent on judgment and fit rather than credentials.
That’s the work the structure conversation keeps burying. Families spend months agonizing over the org chart, in-house versus hybrid, this vertical versus that one, and comparatively little energy on whether the handful of people filling the boxes have the judgment the job actually demands. Technical skill is the easiest thing to screen for and the least predictive of success.
- Will this person earn the family’s trust over the years?
- Exercise discretion when no one is watching?
- Steward wealth they didn’t create, and tell the principal something he doesn’t want to hear?
Those are the questions that decide whether the whole structure holds. None of them fit in a diagram.
Which brings us to cost, the number the glossy pages state almost in passing. Running an investment-focused family office can run up to 1.9% of assets a year. That’s a real, recurring expense, and families should walk into it clear-eyed. But the expensive mistake is seldom the operating budget.
It’s paying that budget, year after year, to the wrong people, or churning through the same seat three times because the first two hires got assessed on a résumé instead of on judgment. The cost of a family office is relatively fixed. The cost of getting its leadership wrong compounds.
So how should a family separate signal from noise?
Strip out the legacy language and ask boring questions.
- What do we actually need this thing to do?
- How much control do we genuinely want, versus how much we like the idea of keeping?
- Is the next generation ready to run what they inherit, or are we building an institution to paper over the fact that they aren’t?
- And above all: who, specifically, is going to lead this, and how confident are we in that judgment?
None of that is as inspiring as “architecting a legacy.” It’s also the entire game.
The families who do this well aren’t the ones who bought the most elaborate structure. They’re the ones who built the smallest structure that solved their actual problem, and put irreproachable people in the seats that matter.
The wealth transfer is real. The growth is real.
The need, for many families, is real. Just remember that a family office is only ever as good as the people running it.
No operating model, however elegant, has ever made a single decision on its own.
