Short answer: The main types of private equity funds are buyout funds, venture capital funds, growth equity funds, real estate private equity funds, infrastructure funds, fund-of-funds, mezzanine funds, distressed funds, and secondary funds. They differ by company stage, control level, use of debt, risk profile, time horizon, and how they create value.
Private equity is not one kind of capital. A founder looking for minority growth capital, a family business considering succession, and an investor allocating to secondaries are dealing with very different fund strategies. Understanding the differences matters because the wrong capital partner can create pressure, governance friction, or an exit path that does not fit the company.
This guide explains the nine common private equity fund types and when each one is usually relevant.
What is a private equity fund?
A private equity fund is a pooled investment vehicle managed by a private equity firm or adviser. Investor.gov's private equity funds overview explains that PE funds pool investor capital and typically focus on long-term investments in assets that may take time to sell. It also notes that PE funds themselves are generally not registered with the SEC and are usually available only to accredited investors and qualified clients.
For companies, the practical question is not "private equity or not?" It is which private capital strategy fits the stage, control needs, risk profile, and value-creation plan.
Private equity fund types at a glance
| Fund type | Typical target | How value is created |
|---|---|---|
| Buyout fund | Mature businesses with stable cash flow | Control, operational improvement, leverage, growth, and exit multiple discipline |
| Venture capital fund | Early-stage high-growth companies | Product-market fit, market expansion, follow-on funding, and portfolio upside |
| Growth equity fund | Scaling companies with proven traction | Capital for expansion, go-to-market scale, systems, and professionalization |
| Real estate private equity | Property assets or real estate platforms | Asset acquisition, development, repositioning, leasing, and financing |
| Infrastructure fund | Essential assets and long-duration projects | Contracted cash flows, operational reliability, capex, and long-term yield |
| Fund of funds | Portfolio of private funds | Diversification across managers, strategies, vintages, and geographies |
| Mezzanine fund | Companies or deals needing junior debt or hybrid capital | Contractual yield plus equity upside or warrants |
| Distressed fund | Stressed businesses, debt, or special situations | Turnaround, restructuring, asset recovery, or claims trading |
| Secondary fund | Existing fund interests or continuation vehicles | Buying mature private-market exposure from existing investors or funds |
1. Buyout funds
Buyout funds acquire controlling stakes in established companies. They may buy from founders, families, corporates, public shareholders, or other sponsors. Many use acquisition debt, so they usually need businesses with predictable cash flow, defensible margins, and room for operational improvement.
Buyout funds are most relevant when a seller wants liquidity, a succession path, a professionalized owner, or a partner to scale through acquisitions. For management teams, the trade-off is control: a buyout fund typically expects governance rights, a clear value-creation plan, and an exit path.

2. Venture capital funds
Venture capital funds invest in early-stage or high-growth companies, often before profitability. VC is frequently discussed separately from private equity, but it is part of the broader private capital ecosystem. The return logic depends on a small number of companies becoming very large.
VC funds are usually relevant when the market is large, the company can scale quickly, and losses are acceptable while the business proves product-market fit or builds category leadership. VC is less suitable for companies that can grow profitably but not at venture scale.
3. Growth equity funds
Growth equity sits between venture capital and buyouts. These funds typically invest in companies that already have revenue traction, a proven product, and a clearer path to scale. They may take minority or structured positions and often focus on sales expansion, hiring, product investment, international growth, or acquisitions.
Growth equity can be attractive for founders who need capital and expertise but do not want to sell control. The key negotiation points are valuation, governance, investor rights, future fundraising expectations, and exit timing.

4. Real estate private equity funds
Real estate private equity funds invest in property assets, portfolios, development projects, operating platforms, or real estate-backed companies. Strategies can range from core income to opportunistic development or distressed assets.
The main diligence questions are asset quality, location, tenant risk, financing, development risk, occupancy, leasing, environmental issues, and exit liquidity. These funds are usually more asset-driven than operating-company PE funds.
5. Infrastructure funds
Infrastructure funds invest in assets such as energy, transport, utilities, digital infrastructure, logistics, water, and social infrastructure. The appeal is often long-duration cash flow, essential-service characteristics, and lower correlation to traditional operating-company risk.
Infrastructure investing can still carry construction risk, regulatory risk, demand risk, counterparty exposure, currency risk, and political risk. For companies, infrastructure funds may be relevant as investors in platforms, projects, concessions, or capital-intensive growth plans.
6. Fund of funds
A fund of funds invests in other private equity funds rather than directly into companies. The purpose is diversification across managers, strategies, geographies, and vintage years. Fund-of-funds investors may use this structure to access private markets without selecting every underlying fund directly.
The trade-off is fee layering and less direct control over portfolio construction. Investors should understand manager selection, underlying exposures, fees, reporting, liquidity, and concentration.
7. Mezzanine funds
Mezzanine funds provide hybrid capital that sits between senior debt and common equity. It may include subordinated debt, payment-in-kind interest, warrants, or preferred equity. Mezzanine capital is often used in buyouts, acquisitions, recapitalizations, or growth situations where senior debt is not enough and common equity would be too dilutive.
For companies, mezzanine capital can be useful but expensive. It requires careful cash-flow planning and covenant review. For sponsors, it can help complete a capital structure without giving away more equity than necessary.
8. Distressed and special situations funds
Distressed funds invest in companies, debt, assets, or claims where value is impaired by financial stress, operational problems, litigation, restructuring, or market dislocation. The strategy may involve turnaround control, debt acquisition, bankruptcy process participation, or asset recovery.
These funds can be relevant when a company needs rescue capital, restructuring, lender negotiation, or a sale under pressure. The risk is that capital may come with aggressive terms, control changes, or limited room for founder preference.
9. Secondary funds
Secondary funds buy existing private equity fund interests, direct stakes, or continuation-vehicle exposure from investors who want liquidity. They do not usually provide primary capital to a company in the same way a growth equity or buyout fund does.
Secondaries matter because they create liquidity in an otherwise illiquid private-market ecosystem. They can also affect companies when a sponsor moves an asset into a continuation vehicle or when investor ownership changes behind the scenes.
How to choose the right private equity partner
For founders and management teams, the fund label is only the first filter. Ask:
- Does the fund usually take control or minority positions?
- Does it invest at our company stage and check size?
- What value does it add beyond capital?
- How does it use debt?
- What is its expected hold period and exit strategy?
- How does it behave when performance misses plan?
- Which decisions will require investor consent?
ILPA's Private Equity Principles emphasize alignment, governance, and transparency in PE partnerships. Those ideas are useful for founders too: the economics matter, but so do decision rights, information flow, and incentives.
Common mistakes
- Assuming all private equity funds want control.
- Treating venture capital and growth equity as interchangeable.
- Choosing the highest valuation without understanding governance rights.
- Ignoring the fund's hold period and exit pressure.
- Accepting debt-heavy structures without downside cash-flow analysis.
- Failing to diligence the investor's track record with similar companies.
