Testing the economics of a billionaire family office conversion
Built on Chapter 16 of The Single Family Office by Richard C. Wilson. Full chapter text: FamilyOffices.com.
Outside client revenue can make an office larger while leaving its owners worse off. The result depends on the cost of delivering the promised service and the capital required to support it. A billionaire family should examine the proposed service company as carefully as any other operating investment.
Chapter 16 describes potential efficiencies from sharing infrastructure. I would test those efficiencies with a separate business model that shows which expenses genuinely stay fixed and which increase as clients arrive.
Count the work behind a better experience
When discussing internal technology, I describe the potential to create custom reports and internal tools that improve client service. The point concerns a specific task the team can perform better. It does not establish that every new service can be delivered at little cost.
For a conversion model, I would identify each proposed improvement and estimate the labor required to maintain it. A custom report may be reusable, but data collection and exception handling still consume employee time. Put those tasks into the budget.
Separate existing spending from new spending
Begin with the private office's current cost base. Identify work that will continue for the founding family regardless of conversion. Then show the additional spending needed to serve outsiders. Keep the two views available so owners can understand both the new business and the family's remaining private-office bill.
Some resources will be shared. Assign their costs according to a method management can explain and update. If an investment professional spends substantial time on outside-client requests, that cost belongs in the business assessment even when the employee was originally hired by the family.
Include services that need external expertise. A proposal to offer broad coordination can require professional support beyond the current team. Do not treat the founder's ability to call a trusted advisor as free capacity available indefinitely to every client.
Distinguish prospective revenue from committed revenue
List signed engagements separately from prospects. For each prospective client, show the service requested and the work needed before onboarding. A large asset figure can be commercially attractive while saying little about whether the client is willing to buy the actual offering.
Understand the timing of receipts and expenses. Employees and vendors may need payment before a client relationship produces cash. Model a slower start so the family can see how much operating support it might be asked to provide.
Avoid solving a weak model by assuming rapid expansion. Additional clients can require another specialist or new systems capacity. Identify those steps explicitly. The owners should know when growth changes the cost base and whether expected revenue covers that change.
Include management attention
A founder who helps win the first client may become the default person for every difficult conversation. That dependence carries a cost. Record the work the founder expects to perform and the employee who should eventually take responsibility for it.
Ask what the founder would otherwise do with the time. For a family with valuable operating holdings, the displaced work can matter more than a modest office expense reduction. The conversion proposal needs to make that tradeoff visible without pretending it can be measured perfectly.
The same issue applies to senior investment staff. If they spend more time in client meetings, someone else must complete the investment work. A model should show whether the business can fund that replacement capacity.
Set a financing boundary
The family should approve how much capital it is willing to commit to the service company and under what conditions additional support can be requested. Management needs a clear process for reporting performance against the plan. Hidden support from the private office makes both operations harder to assess.
Review results by service as well as by client. A relationship may appear profitable in aggregate while one promised activity repeatedly loses money. That finding can lead to a narrower scope or a different delivery method, subject to the engagement and appropriate advice.
Before proceeding, I would ask management to explain the model without relying on the phrase economies of scale. Name the expense being shared, the spare capacity available, and what happens when that capacity runs out. Those answers give the family a business case it can actually examine.
Questions and answers
Should all existing office expenses be charged to outside clients? The allocation should reflect the work performed and the approved arrangements. Owners need a fair view of the service business and the resources still dedicated to the family.
What if the first clients require extra work? Measure it early and compare it with the assumptions. Management should address the scope and cost implications before treating the relationship as proof that the model works.
