Private Equity and Venture Capital

What Private Equity and Venture Capital Are

Private equity is a broad category covering investments in companies that are not listed on a public stock exchange. The term spans everything from buying a controlling stake in a mature manufacturing business to providing growth capital to a software company preparing for an eventual public offering. Venture capital is a subset of private equity focused on early-stage companies — startups — that are often pre-revenue or pre-profit and carry higher risk alongside the possibility of outsized returns.

Together, these two categories sit under the broader umbrella of alternative investments — assets that fall outside traditional public stocks and bonds. For family offices, they are often meaningful parts of the portfolio, not because every family pursues them, but because the organizational infrastructure of a family office is well suited to managing the complexity they bring.

The Fund Structure: GP and LP

Most families access private equity and venture capital through a fund structure. A fund pools capital from multiple investors, deploys it into a portfolio of companies over several years, and eventually returns proceeds back to those investors. Understanding two roles is essential to understanding how this works.

The general partner (GP) is the professional investment manager who runs the fund — sourcing deals, making investment decisions, and overseeing portfolio companies. The limited partner (LP) is the investor — the family, institution, or endowment that contributes capital. LPs have limited liability, meaning their financial exposure is capped at what they invest; they do not run the fund's operations or make its investment decisions. Family offices almost always participate as LPs when investing in funds.

This structure is formalized as a limited partnership, a legal entity designed specifically for this purpose. Each investor signs into the fund as a limited partner and receives periodic statements showing their capital account — their running balance of contributed capital, allocated gains, and distributions received.

Capital Calls and the J-Curve

Unlike buying a public stock where you pay upfront and immediately own shares, private equity funds work on a capital call model. When a family commits to a fund, they are not wiring all the money at once. Instead, they pledge a total amount — their committed capital — and the GP draws it down over time, in pieces, as investment opportunities arise. A family might commit an illustrative $5 million to a fund and receive ten capital calls over three years, each requesting $500,000.

This model creates a well-known pattern called the J-curve. In the early years of a fund's life, the family is contributing capital and paying fees, but the underlying companies have not yet matured or been sold. The net value of the investment often dips below the amount contributed. Over time, as portfolio companies grow and are eventually sold or taken public, proceeds flow back to LPs as distributions, and the curve bends upward. Families who are surprised by this early drag often did not fully anticipate the J-curve dynamic when entering their first fund.

Fees: Management and Carry

Two types of fees define the economics of a private equity or venture capital fund relationship.

The management fee is an annual charge — calculated as a percentage of committed or invested capital — that covers the GP's operating costs: staff, offices, travel, and deal sourcing. It is paid regardless of whether the fund performs well. Think of it as the baseline cost of keeping the manager in business to manage the portfolio.

The more consequential fee is carried interest, commonly called "carry." Carry is the GP's share of the fund's profits above a certain return threshold. It aligns the manager's interests with the LP's: the GP earns its largest reward only when investors do well. The mechanics of how profits are split — and in what order — are governed by a distribution waterfall, which spells out who gets paid first and when the GP begins participating in profits. Attorneys draft these terms carefully, and families should have qualified legal counsel review them before committing to any fund.

Venture Capital and the Power Law

Venture capital has a distinctive return profile that families and their advisors discuss as the "power law." In a typical venture portfolio, a small number of investments — sometimes just one or two — generate the vast majority of the fund's total return. Most other investments in the fund may return little or nothing. This is not a flaw in the model; it is the defining characteristic of early-stage investing, where many startups fail and a few become enormously valuable.

The implication for families is that diversification across many venture funds, managers, and vintage years — the calendar year in which a fund begins deploying capital — matters more than it does in most other asset classes. A family that invests in a single venture fund and happens to miss the fund's best company may see a very different outcome from a family with exposure across several funds and years. Vintage year diversification is the practice of committing to new funds across multiple years rather than concentrating all commitments in one period.

Buyouts, Growth Equity, and the Spectrum

Within private equity, families encounter several distinct strategies. A buyout fund acquires controlling stakes in established, often profitable companies — sometimes using borrowed money alongside equity capital (a structure called a leveraged buyout). Growth equity sits in the middle of the spectrum, investing in companies that are already generating revenue but need capital to scale. Venture capital, as discussed above, anchors the early-stage end.

Each strategy carries a different risk-and-return profile and a different typical fund life. Families often hold exposure across multiple parts of this spectrum as part of their broader asset allocation — the deliberate division of capital across different asset types.

Access, Minimums, and Qualification

Access to private equity and venture capital funds is not universal. Funds typically require investors to meet legal standards — most commonly the qualified purchaser standard in the United States, which sets a threshold based on investable assets. The specific figures are set by law and change; readers should work with qualified attorneys to understand current requirements and how they apply to their situation.

Minimum investment sizes vary widely by fund and manager. Illustratively, some institutional-quality funds set minimums in the range of $1 million to $5 million or more per commitment, though newer fund platforms have lowered entry points for some strategies. Because capital calls are spread over several years, families also need to ensure they have adequate liquidity — accessible cash or near-cash assets — to meet those calls when they arrive. Managing unfunded commitments alongside current liquidity needs is one of the more nuanced operational tasks a family office handles.

Families exploring access to top-tier managers often find that relationships and track record of being a reliable LP matter as much as meeting the financial minimums. This is one reason manager selection is treated as a discipline of its own.

How Fund Investing Differs from Direct Deals

Investing in a private equity or venture capital fund is fundamentally different from direct investing, where a family puts capital directly into a single company without a fund manager intermediating. In a fund, the family delegates deal selection, monitoring, board involvement, and exit decisions entirely to the GP. In a direct deal, the family takes on those responsibilities itself — or alongside a co-investor.

There is also a middle path: co-investments, where a GP offers its LP investors the opportunity to invest additional capital directly into a specific deal alongside the fund, often at reduced or no fees. Co-investments allow families to build deeper exposure to specific opportunities they find compelling without bearing the full cost of running a direct deal process. The mechanics of co-investments, club deals, and direct transactions are covered separately in the co-investments guide.

From an operational standpoint, fund investing requires the family office to track capital call notices, manage wire timing, reconcile Schedule K-1 tax documents that arrive from each fund annually, and measure performance using private-market metrics. The standard measures — internal rate of return, multiple on invested capital, total value to paid-in, and distributions to paid-in — are different from the time-weighted returns used for public portfolios. Families commonly conduct thorough due diligence on both the fund manager and the fund terms before committing, and may also compare private equity allocations against private credit strategies when deciding how to deploy capital into private markets.
