Co-investing promises something many private-market investors want: direct exposure to a selected company, greater visibility over where their capital is going and potentially lower costs than a conventional fund commitment. Yet the apparent simplicity can be misleading. A co-investment concentrates capital in one transaction, often requires a decision within weeks and leaves the investor dependent on much of the same judgement, information and governance infrastructure as the lead manager.
For family offices, pension funds and other sophisticated investors, the relevant question is therefore not whether co-investment is an attractive strategy in principle. It is whether they possess the access, liquidity, expertise and decision-making discipline required to use it without unintentionally weakening the portfolio.
What Co-Investing Actually Means
In private equity, a co-investment usually allows a limited partner to invest directly in a company alongside the general partner’s main fund. The fund may finance most of the transaction, while selected investors provide additional equity through a separate vehicle.
A manager may seek co-investment capital because a transaction is too large for the fund to finance alone, because internal concentration limits restrict how much it can invest in one company or because it wants to strengthen its relationship with important limited partners. The investor, meanwhile, gains exposure to a specific asset rather than another blind-pool fund in which the underlying companies are not known at the point of commitment.
This structure differs from a fully direct investment. The co-investor is not normally sourcing and leading the acquisition independently. It is relying on the sponsor to negotiate the transaction, conduct much of the due diligence, arrange financing, oversee the company and eventually execute the exit.
That distinction matters. Co-investing can provide more transparency than a fund commitment, but it does not necessarily provide operational control.
Why Investors Are Interested
The clearest attraction is cost. Many co-investments are offered with reduced management fees and carried interest, or occasionally without either. When the underlying investment performs well, this can improve the net return relative to exposure obtained through a traditional private-equity fund.
Co-investments can also give investors greater influence over portfolio construction. Rather than accepting the sector, geography and timing selected by a fund manager, an investment office can choose opportunities that complement its existing holdings. A family with expertise in healthcare, industrial manufacturing or software may use that knowledge to evaluate transactions in a familiar field.
For family offices in particular, co-investing can appeal to the entrepreneurial instincts of the principals. It offers a more tangible relationship with an operating business than a conventional fund commitment and may create opportunities to contribute industry contacts, regional knowledge or strategic experience.
Demand remains substantial. In June 2025, Carlyle’s AlpInvest announced that it had raised $4.1 billion for its ninth dedicated co-investment fund, exceeding the $3.5 billion raised for the previous vehicle. Its investor base included pension funds, asset managers and family offices. The scale of such vehicles shows that co-investment has developed into a significant segment of private markets rather than a specialist arrangement available to only a few institutions.
Lower Fees Do Not Mean Lower Risk
The economic advantage of reduced fees is easy to understand, but it should not dominate the investment decision. A weak company purchased at an excessive valuation does not become attractive merely because the investor pays less carried interest.
The more important difference is concentration. A diversified private-equity fund may hold ten or more companies across several industries and investment years. A single co-investment exposes the investor directly to the fortunes of one business, one management team, one capital structure and one eventual exit.
Co-investments are therefore better understood as concentrated additions to a diversified programme, not as lower-cost substitutes for diversification. An investor allocating heavily to a handful of apparently compelling transactions can quickly create hidden exposure to the same economic drivers, particularly when several deals involve similar software, healthcare or consumer businesses.
The current market makes valuation discipline particularly important. McKinsey reported that the median private-equity purchase multiple increased from 11.3 times earnings before interest, tax, depreciation and amortisation in 2024 to 11.8 times in 2025. At the same time, private-equity returns remained subdued relative to public markets and the backlog of companies awaiting an exit reached record levels.
Under those conditions, access to a deal is not the same as access to a bargain.
The Adverse-Selection Question
Every co-investor should ask why the opportunity is being offered.
There are legitimate reasons. The manager may be pursuing a company that would otherwise exceed the fund’s concentration limit. It may want to reserve capital for follow-on investments or include a strategic investor with relevant expertise. Some managers routinely offer co-investments across their investor base as part of a long-established relationship model.
Nevertheless, an investor should examine whether the sponsor is retaining sufficient exposure and whether the transaction would still proceed if external capital were unavailable. A manager may be less enthusiastic about syndicating the most attractive deals when its fund has enough capacity to finance them alone.
The allocation process also creates potential conflicts. Opportunities may be distributed to secure commitments to a new fund, reward strategically important investors or support a broader commercial relationship. The Institutional Limited Partners Association places particular emphasis on transparent allocation policies and alignment between general and limited partners.
Investors should understand who received the opportunity, how allocations were determined and whether the economics differ between participants. Preferential access is valuable only when the underlying selection process is credible.
Can Your Team Evaluate The Deal In Time?
Co-investment decisions often arrive with compressed deadlines. The lead manager may have spent months studying a company, while the co-investor receives access to the investment memorandum, financial model and data room shortly before capital must be committed.
This creates an informational imbalance that cannot be eliminated simply by hiring an external adviser. The investor must decide which parts of the sponsor’s underwriting it can independently test, which assumptions deserve the most scrutiny and which risks cannot be resolved within the available time.
A credible internal process should examine the quality of earnings, customer concentration, leverage, cash conversion, management incentives, regulatory exposure and the assumptions behind the exit valuation. It should also test how the company performs under a less favourable scenario, including slower growth, lower margins, higher financing costs or a delayed sale.
The question is not whether the investment team can reproduce every part of the sponsor’s work. It is whether it can reach an independent judgement rather than merely confirm the lead investor’s conclusion.
A family office without sufficient staff may be better served by a dedicated co-investment fund or an advisory platform that screens and diversifies opportunities. This introduces another layer of fees, but it may provide better governance than attempting to approve direct transactions through an overstretched investment committee.
What To Ask The Lead Manager
The first questions should concern the sponsor’s own conviction. How much is the main fund investing? Does the transaction receive the same economics and governance protections as comparable deals held entirely within the fund? Is the sponsor or its senior team committing personal capital?
Investors should then examine why additional equity is required. A co-investment used to complete an unusually large but strategically coherent acquisition is different from one needed because leverage providers have reduced their commitments or because the sponsor has struggled to assemble the financing.
The investment case should explain how value will be created without relying mainly on multiple expansion. Operational improvements, pricing, new products, acquisitions and international growth may all contribute, but each requires evidence, capital and competent execution.
The exit assumptions deserve particular scepticism. Private-equity firms are holding assets for longer as weak distributions and slower sales restrict liquidity across the industry. An investor should model the effect of a seven-year holding period rather than assuming that the company will be sold according to the sponsor’s preferred timetable.
The Liquidity Commitment Is Larger Than The Initial Cheque
Co-investments are illiquid, and the capital may remain tied up for substantially longer than expected. The investor must also be prepared for follow-on requirements.
A company may need additional equity to finance an acquisition, meet a lender requirement or protect the balance sheet during a downturn. Investors that cannot participate may suffer dilution or become dependent on other shareholders to supply rescue capital.
This makes liquidity planning essential. A co-investment programme should include reserves for follow-ons rather than treating the initial subscription as the maximum exposure. The investor must also consider capital calls from its underlying private-equity funds, which may arrive during the same difficult market period in which portfolio companies require additional support.
The attraction of direct deal access can obscure this portfolio-level reality. Capital is committed one transaction at a time, but liquidity risk accumulates across the entire private-markets allocation.
How To Build A Co-Investment Portfolio
Diversification should be assessed across managers, sectors, geographies, strategies and investment years. Ten co-investments do not create a balanced portfolio when eight are technology buyouts completed at similar valuations during the same market cycle.
Position sizing matters as much as deal selection. A disciplined programme establishes a maximum exposure to any one company and limits the aggregate allocation to co-investments relative to diversified funds and liquid assets.
Investors should also track indirect exposure. A company offered for co-investment may already sit inside one of the investor’s existing funds. The direct allocation increases exposure to that asset beyond what appears in a simple list of portfolio companies.
A measured approach is often more effective than trying to participate in every opportunity. Declining deals is part of the strategy, not evidence that the programme has failed to deploy capital.
When A Co-Investment Fund May Be Better
Investors who want the economic and portfolio benefits of co-investing but lack the resources to assess individual transactions can use a specialist co-investment fund. The manager evaluates and assembles deals across several sponsors, potentially providing broader diversification and a more consistent deployment programme.
The trade-off is reduced discretion. The investor no longer selects every company and must pay an additional layer of management fees and performance compensation. It is also necessary to assess the co-investment manager’s access, selection process and ability to avoid adverse selection.
A fund can nevertheless be more suitable for smaller investment offices. Paying for professional underwriting may be preferable to pursuing nominally fee-free deals without the staff, systems or governance required to evaluate them properly.
What Good Governance Looks Like
A co-investment policy should be agreed before an attractive opportunity appears. It should define permitted sectors and geographies, position limits, return requirements, leverage tolerances and the circumstances in which external legal or commercial due diligence is mandatory.
Investment committees need enough independence to challenge the enthusiasm created by a prestigious sponsor or apparently exclusive allocation. A short deadline should not become a reason to lower standards. When the available information is insufficient, the correct decision may be to decline.
The legal structure also requires attention. Investors should understand voting rights, information rights, transfer restrictions, dilution provisions, exit arrangements and the expenses allocated to the co-investment vehicle. Minority investors generally cannot determine when a company is sold, even when their capital has been held longer than anticipated.
Reporting should continue after the transaction closes. Performance needs to be measured against the original underwriting case, with changes in leverage, operating results and valuation assumptions clearly documented.
Who Is Co-Investing Best Suited To?
Co-investment is most credible for investors that already have a diversified private-markets programme, established relationships with high-quality managers and sufficient capital to build exposure across multiple transactions. They also need a team capable of responding quickly without abandoning independent analysis.
It may be less suitable for investors seeking their first exposure to private equity, those with limited liquidity or those hoping that direct deals will provide easy access to superior returns. A diversified fund is often a more appropriate starting point because it spreads manager and company risk while allowing the investor to learn how private-market cash flows behave.
Family offices with genuine industry expertise may have an additional advantage, but operating experience should not be confused with investment capability. Understanding a sector does not remove the need to analyse valuation, leverage, governance and exit risk.
Co-investing can reduce fees and give investors more deliberate control over portfolio construction, but it also transfers more responsibility to the investment office. Its benefits are strongest when access is supported by independent underwriting, disciplined position sizing and realistic liquidity planning. Used selectively, it can complement a diversified private-equity allocation. Used primarily as a source of inexpensive or exclusive deals, it can turn apparent control into concentrated risk.
