Single vs. Multi-Family Offices: Structure and Deal Appetite Compared

Family offices have become a significant source of capital for startups, funds and private deals. But "family office" covers very different organisations. A single-family office serves one wealthy family. A multi-family office serves several families under one roof. The difference shapes how they invest, how quickly they decide and how founders should approach them.

This guide compares the two models and explains what each means for anyone raising capital.

1. Single-Family Offices

• Serve one family, managing its investments, and often its tax, legal, philanthropic and personal affairs.
• Full control and privacy. The family sets its own strategy and priorities.
• High cost. Running a dedicated team is expensive, so single-family offices are usually established by families with very significant wealth.
• Flexible mandates, shaped by the family's interests, history and risk appetite.

2. Multi-Family Offices

• Serve multiple families, sharing investment teams, research and services.
• Lower cost per family, making professional wealth management accessible to families with less wealth.
• More standardised processes, with investment committees and formal policies.
• Fiduciary and regulatory obligations, often operating as registered advisers.
• Pooled opportunities, sometimes offering co-investments or funds across client families.

4. How to Approach Each

Single-family offices

• Find a trusted introduction; many avoid cold outreach.
• Understand the family's interests, including its original business and values.
• Identify the decision-maker, whether a principal, chief investment officer or next-generation member. See next-gen family office principals.
• Offer a relationship, not just a transaction.

Multi-family offices

• Fit their investment process and prepare thorough materials.
• Expect formal due diligence and committee review.
• Consider pooled structures, since they may invest across several client families.
• Show risk management and alignment with fiduciary standards.
