What it is
In a co-investment, a lead sponsor identifies and underwrites a transaction, then offers a limited group of outside investors the chance to participate directly in that single deal. The investor holds an interest tied to one company or asset instead of a diversified pool managed by the sponsor.
Families are often interested because co-investment can offer greater transparency into what they own and more control over concentration and timing. It also shifts more responsibility to the investor, because the decision to participate is made deal by deal.
Co-investment sits within the broader field of direct investing. It is distinct from investing as a limited partner in a fund, and from leading a transaction independently. Terms, access and economics vary by sponsor and by deal, and they are negotiated case by case.
How it’s traditionally been approached
Historically, co-investment opportunities have flowed through existing relationships. A family that was already a limited partner in a sponsor's fund might be invited to participate when a deal needed additional equity or when the sponsor wanted to limit its own concentration.
Evaluation has typically involved reviewing the sponsor's materials, the investment thesis, the capital structure and the legal documents. Because timelines can be short, families have often relied on in-house professionals, outside counsel and trusted advisors to assess an opportunity quickly.
Approaches differ widely. Some families build internal direct-investing teams, some co-invest selectively alongside a small set of familiar sponsors, and others prefer fund commitments for diversification and delegated oversight. Each reflects different resources, risk tolerance and goals.
How the right family office may help
The right multi-family office may help a family think about co-investment as part of a whole portfolio rather than as isolated deals. That can include clarifying how much illiquidity, concentration and time commitment the family is comfortable with, and how a single position relates to everything else it owns.
In a first conversation, an MFO or direct-investing specialist will generally ask about your goals, liquidity needs, existing holdings, governance and decision-making process. It may also explain how it sources opportunities, how it conducts due diligence, and how it works with your attorneys, tax professionals and accountants.
Useful questions to ask include: How are conflicts of interest identified and disclosed? Who performs diligence, and who makes the final decision? How is the sponsor's track record verified? How are compensation and any deal-related economics explained? What would the process look like if timing is compressed? A thoughtful provider should answer plainly and acknowledge what cannot be known in advance.
The bigger picture
Committing capital to a single private transaction can carry emotional weight as well as financial weight. Concentration, limited liquidity and long holding periods can affect how settled a family feels, particularly when several generations have different expectations about risk and involvement.
A clear process, defined roles and honest conversations about tolerance for uncertainty may support better sleep and healthier family dynamics. Wellbeing and finances are connected, and many families find it helpful to decide in advance what a good outcome looks like beyond the numbers.

What is family office co-investment?
Family office co-investment is when a family office invests directly in a specific transaction alongside a lead sponsor, such as a private equity or venture firm. The family holds an interest in that one deal rather than in a diversified fund. Terms and access vary by sponsor and by transaction.
How is co-investment different from investing in a fund?
In a fund, a manager selects investments on behalf of many investors from a pool of capital. In a co-investment, the investor evaluates and chooses a particular deal. This can offer more transparency and control, and it also requires more diligence and carries more concentration.
How do family offices find co-investment opportunities?
Most opportunities come through relationships, such as existing fund commitments, networks of other families, and sponsors who invite selected partners. A multi-family office may help a family organize its sourcing criteria and evaluate what it receives. Access is never guaranteed.
What due diligence is typically involved in a co-investment?
Diligence generally covers the sponsor and its approach, the business or asset, the capital structure, valuation assumptions and the legal terms. Families often rely on their own attorneys, tax professionals and accountants for specialized review. Timelines can be short, so having a process in place beforehand can help.
Can a multi-family office help with co-investment?
A multi-family office may help by coordinating diligence, fitting a potential deal into the family's overall portfolio, and working with the family's other advisors. Services differ from one firm to the next, so ask each provider exactly what it does and does not do. It remains your responsibility to decide, with your licensed advisors.
What risks should families understand before co-investing?
Co-investments can be illiquid, concentrated in one company or sector, and dependent on the sponsor's decisions. Capital may be lost in whole or in part. Understanding your liquidity needs and your tolerance for uncertainty before reviewing any deal is generally considered prudent.
