You can understand why a business is a good investment without wanting to find the seller, negotiate the acquisition, and arrange the financing yourself. A co-investment separates those jobs. Someone leads the transaction; you decide whether that particular company deserves a place in your portfolio.
Private equity co-investments give investors exposure to a specific private company alongside a lead investor or sponsor. They can offer a closer view of the business and its investment terms than a commitment to a fund whose future acquisitions have yet to be selected. Before investing, establish which decisions remain yours and which responsibilities belong to the lead investor.
This guide explains private equity co-investment structures, where to find opportunities, and the costs and ownership rights to review.

What is a private equity co-investment?
A private equity co-investment is an investment in a particular company alongside another investor leading or sponsoring the transaction. A participant may invest directly in the acquisition vehicle or through a separate vehicle that pools several investors. The defining feature is exposure to an identified transaction.
In institutional private equity, a fund manager may offer investors a separate allocation alongside its main fund. Independent sponsor transactions work differently: the sponsor identifies an acquisition and assembles capital specifically for it, without drawing the purchase equity from a traditional committed fund. Both can give a co-investor a company-level decision, but the capital relationships and governing documents differ.
A co-investment fund adds another distinction. Its manager can select a portfolio of co-investments on investors’ behalf. Owning that fund is different from personally selecting each underlying company. The comparison of direct private equity investing and funds examines the differences in diversification, fees, and investor workload.
How does a co-investment work?
The sponsor develops the investment thesis, negotiates the acquisition, coordinates diligence and financing, and establishes the ownership plan. Co-investors evaluate the opportunity and subscribe for interests under the agreed terms. After closing, management operates the company while the sponsor and other owners exercise their negotiated oversight rights.
Who leads the acquisition and who runs the company?
Sponsor
Sources and leads the acquisition, develops the plan, and oversees the investment.
Co-investor
Evaluates the business and terms, selects an allocation, and receives agreed economic and information rights.
Management
Runs the business, hires the team, serves customers, and executes the operating plan.
Participation can happen through a special purpose vehicle, or SPV. That vehicle holds an interest in the acquisition and handles the pooled investors’ administration. It can simplify the company’s ownership register, but an investor still needs to understand the rights at both levels: the rights held by the SPV and the rights the investor has within it.
Review the lead investor’s commitment alongside the terms offered to you. Investors can have different fee arrangements, preferences, or governance rights even when they own interests in the same business. ILPA’s institutional guidance calls for clarity about co-investment allocations, expenses, and differentiated economics.1
Co-investment example: evaluating a distributor acquisition
Consider a hypothetical distributor supplying consumables to independent laboratories. Customers reorder frequently, the company has long-standing supplier relationships, and the retiring owner still approves most purchasing and pricing decisions. The investment case is to preserve those relationships while building a business that can grow beyond the founder’s personal capacity.
An independent sponsor proposes recruiting a purchasing manager, introducing customer-level margin reporting, and adding a sales representative in an adjacent territory. The investor does not have to run the distributor. The investor does have to judge whether the proposed improvements are credible and worth their cost.
| Investment claim | Evidence to request | Why it changes the decision |
|---|---|---|
| Customers reorder reliably | Customer retention, order frequency, and sales by account | Repeat purchases must survive the founder’s departure. |
| Pricing can improve | Margin by product and customer, supplier terms, competitor pricing | A higher price is useful only if volume and relationships hold. |
| Management can take over | Hiring budget, named responsibilities, and transition agreement | The operating plan needs someone with the time and authority to deliver it. |
| Expansion can fund itself | Inventory, receivables, hiring costs, and lender capacity | Growth can consume cash before it produces distributions. |
The value of choosing the company is that these questions can shape the investment decision before capital is committed. If the purchase price already assumes flawless expansion, the attractive business may still be an unattractive investment.
Where do investors find co-investment opportunities in private equity?
Investors find private equity co-investments through relationships with fund managers, independent sponsors, family offices, and investment groups like CapitalPad that offer access to individual transactions. The route determines who selects the opportunities presented, what diligence support is available, and whether the investor can meet the transaction’s minimum investment.
CapitalPad is a private equity co-investment group through which accredited investors participate in individual lower middle market private equity transactions in the United States and Canada. CapitalPad invests in independent sponsor transactions involving businesses with at least $1 million of EBITDA. Individual investments generally start at $25,000.2
| Route | Who selects the company? | Question to resolve |
|---|---|---|
| Direct allocation from a sponsor or fund manager | The investor accepts or declines the offered transaction. | What relationship, check size, and execution capability are required? |
| Deal-specific co-investment group | The group screens opportunities; each participant decides whether to invest. | What costs and rights apply at the investor-vehicle level? |
| Co-investment fund | The fund manager selects investments within its mandate. | How does the manager construct and manage the portfolio? |
Access should be judged by the quality of the opportunity and the materials available to evaluate it. A long list of transactions is less useful than a smaller set whose sponsor, economics, and business plan you can understand.
What should a co-investor evaluate?
A co-investor should evaluate the business, the price, the financing, the sponsor, and the security the investor will actually hold. Those elements determine whether the company can meet its obligations and how any resulting value is shared.
Start with the operating business: durable demand, customer concentration, cash conversion, management, and the changes needed after closing. Then examine how much debt the business must service and whether the plan remains workable if growth arrives later than expected.
At the ownership level, establish whether investors hold common or preferred equity, who controls major decisions, how new equity can dilute existing holders, and what information will be supplied. Follow-on funding deserves particular attention. Review whether this investment can require additional contributions, how further capital may be raised, and how investors who do not participate could be diluted. The ability to decline a separate deal does not resolve those questions.
Finally, assess the sponsor’s relevant experience and financial alignment. A good record in a different industry, capital structure, or role is not automatically a record of doing this transaction well. CapitalPad’s independent sponsor evaluation framework develops these questions around the sponsor, business, structure, and execution.
Are private equity co-investments cheaper than funds?
Some co-investments have lower fees than a conventional fund commitment, but co-investing does not automatically mean investing without fees or carried interest. The comparison depends on the lead sponsor’s economics, transaction expenses, and any separate investor vehicle or access arrangement.
An institutional limited partner offered a direct allocation alongside a fund may receive economics that are unavailable through a pooled co-investment vehicle. Compare the total amount that goes to work, recurring charges, profit participation, and whether underlying sponsor costs have already been deducted from the return illustration.
Two offers quoting the same projected company return can produce different investor outcomes. Our guide to private equity fees explains how to compare those layers without counting the same expense twice.

Common questions about private equity co-investments
Does co-investing give me control of the company?
Not necessarily. Selecting an investment is different from controlling it. Your voting, information, and consent rights depend on the security and vehicle documents, and the sponsor or other owners may control the board.
Do I need to invest in a fund first?
Some fund-manager co-investment programs are relationship-based and may prioritize existing limited partners. An independent sponsor transaction does not inherently require a separate fund commitment. Each access route has its own criteria.
Can I sell a co-investment before the company exits?
Usually there is no public market for a private equity co-investment. An early sale depends on the transfer rules and finding a buyer, so investors should expect a long-term commitment.3
