Family offices have become an increasingly important source of capital in private markets. While their traditional role has been to preserve wealth for future generations, many family offices today are much more active investors than they once were. It’s now common to see them participating in venture capital, private equity, real estate, and a variety of other alternative investments.
For founders, fund managers, and co-investors, having a basic understanding of how family offices operate can be helpful. Roughly 8,000 family offices worldwide manage over $3 trillion today, with both figures expected to grow by more than 70% by 2030, according to Deloitte. These organizations often approach investing differently from traditional institutions, and their long-term perspective can make them valuable partners.
What Is a Family Office?
At its simplest, a family office is an organization created to manage the financial affairs of a wealthy family. That usually includes overseeing investments, but it can also involve tax planning, estate planning, philanthropy, and other aspects of managing family wealth.
Family offices generally fall into two main categories.
Single-Family Offices (SFOs) are dedicated to one ultra-high-net-worth family and handle nearly all aspects of that family’s financial life.
Multi-Family Offices (MFOs) serve several families at once. They offer many of the same services but operate with shared resources, which allows families to access professional investment management without building a full in-house team.
In both cases, the goal is to bring structure and oversight to what are often complex and highly diversified portfolios.
Why Family Offices Are Becoming More Active Investors
Over the past decade, many family offices have become more involved in private markets, particularly in direct investments. There are a few reasons for this shift.
One of the biggest is the time horizon. Family offices often invest with a multi-generational outlook, which means they’re not under the same pressure as traditional funds to exit investments within a specific timeframe.
They also tend to have more flexibility when it comes to how and where they allocate capital. Without rigid mandates, they can explore opportunities across industries, geographies, and asset classes.
Another factor is the growing interest in direct investing. Rather than only investing through funds, some family offices prefer to invest directly in companies or projects they believe in. This allows them to be closer to the investment and sometimes more involved in the long-term development of the business.
Anecdotally, we’ve seen a trend where as 1st generations age (those who may have “founded” the family office), the 2nd, 3rd, and following generations in the office are wanting to be more creative on building capital and making higher risk investments.
Because of these factors, family offices are increasingly seen as attractive partners by both entrepreneurs and fund managers.
How Family Offices Build Portfolios
Most family offices aim to build diversified portfolios that balance long-term growth with capital preservation.
Their investments often include a mix of:
Public equities and fixed income
Venture capital and private equity funds
Direct investments in private companies
Real estate and real assets
Other alternative investments, such as infrastructure or energy
The exact allocation varies widely depending on the family’s goals, liquidity needs, and tolerance for risk.
In some cases, larger family offices have even built internal investment teams that source deals, conduct due diligence, and participate directly in investment rounds.
The Operational Side of Managing Wealth
Behind the scenes, running a family office can be surprisingly complex.
Managing a portfolio that spans multiple asset classes and investment structures requires careful organization. Teams need to track performance, manage capital calls and distributions, store documentation, and prepare reporting for family members and advisors.
As portfolios grow, many family offices find that spreadsheets and manual processes are no longer enough. As a result, many are adopting technology platforms that help them better monitor investments and streamline reporting.
A Long-Term Mindset
One of the defining characteristics of family offices is their long-term perspective. Because they are responsible for managing wealth across generations, many place a strong emphasis on governance, disciplined investment processes, and preparing the next generation to take on future responsibilities.
This long-term mindset can be particularly valuable in private markets, where investments often take years to fully mature.
Approaching Family Offices for Investment
Family offices aren’t just another source of capital, they’re potential long-term partners. If you’re looking to engage one, start by doing your homework: understand their investment style, past deals, and what drives them beyond returns.
Tailor your pitch to show not just the opportunity, but how it fits their values and long-term goals. Bring your diligence materials upfront and be ready to answer detailed questions—family offices value transparency and preparation. Whenever possible, get warm introductions through trusted advisors or networks; cold emails rarely make it through the noise.
And remember, this is a marathon, not a sprint: building trust and demonstrating commitment over time can open doors that a single pitch never will. Approach thoughtfully, and you could turn a one-time investment into a lasting partnership.
