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.
