Managing great wealth is a full-time operation. For families with $30M+ in assets, the question isn’t if you need professional help — it’s how you structure it. And increasingly, the answer is not the traditional Single-Family Office (SFO), but its leaner, more strategic cousin: the Multi-Family Office (MFO).
This guide walks you through what a Multi-Family Office is, why it’s rapidly becoming the preferred model, and how to engage or establish one — all through the lens of cost-efficiency and access to elite expertise.
Step 1: Understand What a Multi-Family Office Really Is
At its core, a Multi-Family Office (MFO) is a wealth management firm that serves multiple unrelated high-net-worth families under one umbrella. Unlike a bank or generic investment advisor, an MFO offers bespoke services typically reserved for a single-family office, but at shared cost and scale.
MFOs typically provide:
- Investment management
- Estate and tax planning
- Family governance
- Philanthropy advisory
- Lifestyle services (concierge, private education, travel, etc.)
- Risk mitigation and insurance structuring
- Succession planning
The key differentiator? Shared infrastructure. This allows families to tap into elite services without bearing 100% of the cost.
Step 2: Know the Breakpoint — When an MFO Makes More Sense Than an SFO
Single-Family Offices are like bespoke private companies set up to serve just one family. While they offer full control and customization, they come with massive fixed costs — typically $2M–$10M+ annually, depending on scope and headcount.
If your net worth is under $250 million, an SFO may be overkill.
Many families in the $30M–$250M range find that MFOs deliver 80–90% of the value at 30–40% of the cost.
Multi-Family Offices pool resources and talent, allowing families to:
- Access a broader team of experts
- Share legal, accounting, and infrastructure overhead
- Pay variable (not fixed) fees aligned with assets or services
- Gain buying power and institutional-grade investment access
This creates significant cost efficiency while maintaining high-touch, family-centric service.
Step 3: Analyze the Strategic Advantages of MFOs
MFOs are not just cheaper — they’re often smarter strategically:
Broader Talent Access
MFOs can afford to hire top-tier legal, tax, and investment professionals that an SFO couldn’t sustain alone.
Institutional-Level Infrastructure
From reporting software to cybersecurity to due diligence platforms, MFOs run on enterprise-grade systems that are cost-prohibitive for SFOs.
Conflict-Free Advice
The best MFOs operate on a fee-only fiduciary model, avoiding product pushing or conflicted incentives common at private banks.
Collaboration and Idea Flow
MFO clients often benefit from cross-family learning, access to co-investment opportunities, and more agile governance frameworks.
Step 4: Choose Your MFO Model
There are two main ways to engage with a Multi-Family Office:
1. Join an Existing MFO
Most families start here. You pay a management fee (usually a % of AUM or flat retainer), and in return, receive access to a menu of services.
Look for:
- Fee transparency
- Team bios and turnover rates
- Customization options
- Governance and reporting tools
Tip: Some elite private banks offer MFO-style platforms — but be wary of hidden product incentives.
2. Establish Your Own MFO Platform
Larger families ($250M–$1B+) sometimes build or sponsor a platform that serves themselves and a few aligned families.
Why do this?
- More control and tailored structure
- Ability to handpick client families
- Shared risk and cost
- Potential to evolve into a commercial MFO
This hybrid model offers the culture of an SFO with the cost-sharing of an MFO.
Step 5: Vet the Right MFO Partner
Choosing an MFO is like choosing a long-term strategic advisor. Ask these questions:
- What’s your ownership structure? (Avoid firms owned by banks or asset managers.)
- Do you receive any commissions or third-party incentives?
- Can I customize the service stack?
- What’s your turnover rate and succession plan?
- How do you protect my data and privacy?
Pro tip: Look for firms with flat hierarchies, integrated teams, and proven multi-generational success stories.
Step 6: Monitor, Evolve, and Empower Your Family
Once onboarded, families should treat the MFO relationship as dynamic. Wealth evolves. So do needs, family structures, and global markets.
Set quarterly strategy reviews, implement a family charter, and consider engaging in family education programs — many MFOs offer in-house curricula.
The Bottom Line: MFOs Are Smart Wealth Architecture
In a world where wealth alone no longer guarantees legacy, Multi-Family Offices offer a rare combination: institutional expertise at a shared cost, customized for human complexity.
They’re not just a cheaper alternative — they’re a strategic force multiplier for modern wealth holders.
If your family is evaluating wealth management structures, ask not just what you can afford — ask what enables your legacy to thrive.
Interview 2–3 MFOs. Challenge them on cost, transparency, and talent. And choose the one that treats your complexity as an opportunity — not a transaction.
