What is a Fund of Funds?

A fund of funds (FoF) is a pooled investment vehicle that raises capital from investors and allocates that capital across multiple underlying private funds, rather than investing directly in companies or assets. The fund of funds manager acts simultaneously as a general partner to its own investors and a limited partner in each of the underlying funds it backs.

For investors, a FoF provides diversified exposure to a basket of fund managers through a single commitment. For the manager running the FoF, it is an operationally complex vehicle that requires coordinated capital calls, multi-layered reporting, and accurate registry data across dozens of underlying funds. This guide explains how a fund of funds is structured, the strategies they typically use, the fee model, and what makes them operationally distinct from a single-strategy private fund.

Definition and Scope

A fund of funds invests in other funds. The defining characteristic is that the FoF does not hold direct positions in companies, properties, or loans. Its portfolio is made up of stakes in other commingled vehicles. Those underlying funds, in turn, hold the underlying assets.

FoFs exist across private equity, private credit, venture capital, hedge funds, real estate, and infrastructure. In private markets, the most common form is a private equity fund of funds, where a manager raises a single closed-end vehicle and uses the capital to make commitments to a portfolio of buyout, growth, venture, or secondary funds. The result is a single LP relationship for the underlying GP and a single GP relationship for the investor in the FoF, with the FoF manager intermediating both.

A FoF is distinct from a feeder fund. A feeder fund pools capital and channels it into a single master fund. A FoF allocates across multiple unrelated managers and strategies.

The Structure of a Fund of Funds

Fund of funds vehicles are almost always structured as limited partnerships, mirroring the legal structure of the underlying private funds they invest in. According to Carta, the limited partnership is the dominant structure across both US and Cayman-domiciled FoFs in private equity.

Three actors define the structure:

• General Partner (GP): The fund of funds manager. Responsible for strategy, manager selection, due diligence, capital calls, distributions, and reporting to the FoF's investors.
• Limited Partners (LPs): The investors in the fund. Typically pension funds, endowments, family offices, sovereign wealth funds, and high-net-worth individuals seeking diversified private market exposure without the cost of building an in-house allocation team.
• Underlying funds: The portfolio. The FoF holds an LP interest in each underlying fund, which is itself a separate limited partnership operated by a different GP.

Capital flows in two directions. Investors in the FoF respond to capital calls from the FoF's GP, who in turn responds to capital calls from each underlying fund's GP. Distributions follow the same path in reverse, often passing through the distribution waterfall at the underlying fund before being aggregated and re-distributed by the FoF.

Common Fund of Funds Strategies

A FoF is not a single strategy. Most FoFs allocate across three approaches, often blending all three within a single vehicle.

Primaries

Primary commitments are direct investments in newly raised underlying funds. The FoF commits capital during a fund's primary fundraise and is treated as a standard LP for that fund's life. Primaries provide vintage diversification and access to top-quartile managers that may be closed to new investors at the individual LP level.

Secondaries

Secondary investments are purchases of LP interests in existing private funds from sellers seeking liquidity. A FoF with a secondaries allocation can shorten the J-curve, deploy capital faster, and gain exposure to mature portfolios at known valuations. For a detailed treatment, see our guide on what a secondaries fund is.

Co-Investments

Co-investments are direct investments alongside an underlying GP into a portfolio company or asset. The FoF invests on the GP's diligence and deal terms, typically at reduced or zero fees. This improves net returns by reducing fee drag at the FoF level.

Fee Structure and the Layered Fee Problem

Fund of funds vehicles charge two layers of fees: those charged by each underlying fund, and those charged by the FoF itself for selection, oversight, and administration.

A typical FoF charges a management fee of roughly 0.5% to 1.0% of committed capital and a performance fee, often referred to as carried interest, of around 5% to 10% above a preferred return. These sit on top of the standard 2 and 20 fees charged by most underlying private equity funds.

The layered fee model is the most common investor objection to FoFs. The counter-argument, supported by Vanguard's September 2025 Private Equity Perspectives paper, is that diversified FoFs have historically delivered lower variance of returns than single-fund investments, and that the access, diligence, and operational expertise provided by experienced FoF managers can justify the additional fee layer for investors without the scale to build a direct private markets programme.

Traditional Operations Versus a Modern Approach

The operational profile of a fund of funds is materially harder than a single-strategy private fund. A FoF GP must:

• Manage capital flows in both directions: outbound to its own LPs and inbound from underlying funds.
• Reconcile multiple capital account statements: each arriving from a different underlying GP on different schedules and in different formats.
• Maintain an accurate unit registry: reflecting every LP's pro-rata interest in the entire portfolio.
• Aggregate performance reporting: across multiple vintages, strategies, and underlying managers into a single coherent narrative for FoF investors.
• Apply look-through reporting: for FATCA/CRS, AML, and regulatory disclosures across the underlying fund layer.

For decades, this work has been done in spreadsheets, email, and PDFs. A typical FoF operations team spends most of its quarter pulling underlying GP reports, manually re-keying figures into a master register, and then reformatting the data into investor-facing reports. The work is not just expensive. It is error-prone, with manual reconciliation between underlying GP statements and the FoF's own registry creating the most common source of restatements.

Modern FoF operators are moving away from this model. Software now exists that can ingest underlying GP statements, reconcile them against expected capital calls and distributions, and update a centralised registry without manual intervention. Investor reporting can be generated on demand rather than assembled from scratch each quarter.

Why the Fund of Funds Model Still Matters

Despite a declining share of overall private equity fundraising, fund of funds remain a critical access channel. According to Preqin, FoF capital raised fell from around 15% of total private equity fundraising in 2007 to closer to 5% by 2017, yet allocations from family offices and smaller institutions continue to flow into the format.

Two groups depend on the model. The first is smaller institutional investors and family offices that lack the staff or check size to build a diversified direct programme. A FoF gives them instant exposure to 15 to 30 underlying managers in a single commitment.

The second is investors seeking specific strategy access in secondaries, emerging managers, or geography-specific allocations, where a FoF can be the most efficient way to deploy capital at scale without paying for an internal allocation team.

For the FoF manager itself, the strategic challenge is operational. The layered structure means margins are thinner than for a direct fund, and any efficiency gain in administration translates directly into either better net returns for LPs or higher operating margin for the GP.

How Caruso Supports Fund of Funds Operators

Caruso is built for the operational reality of multi-layered fund structures. FoF managers running on Caruso use the platform to:

• Maintain a single source of truth across the FoF and its underlying fund holdings through Caruso's unit registry services, with every underlying capital call, distribution, and NAV update reflected in the FoF's own books.
• Manage inbound and outbound capital calls so the GP can coordinate the timing of LP draws against expected calls from underlying funds.
• Provide LPs with consolidated reporting through Caruso's investor portal, with self-service access to capital account statements, distribution notices, and tax documents across the FoF's entire holding period.

For managers operating in private equity, Caruso for private equity provides purpose-built workflows for closed-end structures, including the multi-vintage reporting and look-through compliance that FoF operators need.

Conclusion

A fund of funds is a pooled vehicle that invests in other private funds rather than direct assets, structured as a limited partnership and run by a GP who is simultaneously an LP in every underlying fund. The model offers investors diversified access and the FoF manager a scalable distribution business, but only if the operational layer can keep pace with the structural complexity. The managers building credible FoF businesses today are the ones treating fund administration as a software problem first and a manual process second.
