One Decision Selects a Manager; the Other Selects a Company
The main difference between a fund investment and a co-investment is what the LP is choosing. In a fund, the LP selects the manager and delegates the company decisions; in a co-investment, it also evaluates a specific company, security and price.
Clear allocation rules matter because access can influence judgement. ILPA's private-equity guidance addresses disclosure and expense sharing in co-investments. Those rules help the LP assess the opportunity on its own merits instead of treating an invitation as proof of quality.
Compare the fund economics first. Carta notes that 2% management fees and 20% carried interest are common venture terms. The LP should then add every fee and carry charge attached to the specific co-investment route.
The decision comes down to responsibility. What does the investor want to control? It also needs to know what review it can complete in time and how much company risk the total portfolio can absorb.
The Same Cheque Buys a Different Unit of Risk
A $10 million commitment represents 10% of a $100 million fund that may own several companies. Put the same $10 million into one co-investment and the entire cheque depends on that company. The cheque is still $10 million. Its risk is now concentrated in one company.
- Fund investment: The LP commits capital to a pooled vehicle. The GP calls and deploys that capital across a portfolio under the fund's investment plan.
- Co-investment: The investor participates directly or through an SPV in a specific company, usually alongside a lead investor or sponsor.
The fund review concentrates on the manager and proposed construction. The co-investment review can examine the company directly, although the timetable is often shorter and the final allocation may change near closing.
Knowing the Company Is Only the Beginning
The holding route determines how rights and information reach the LP. Direct ownership places the investor on the company security. An SPV places another legal vehicle between them, so the LP should trace the SPV fees, carry, and layered economics; a sponsor-led syndication may divide one financing round across several pools of capital.
- Direct participation: The investor owns the company security and relies on the rights in the financing and shareholder documents.
- SPV participation: The investor owns an interest in a vehicle that holds the company security. Governance and information may flow through the SPV manager.
- Sponsor-led allocation: A lead investor may retain part of a financing for its main fund and make the balance available to other investors.
Suppose a company raises $100 million and the lead takes $60 million. The remaining $40 million is syndicated. A $10 million co-investment represents 25% of that syndication pool but only 10% of the full round. Both figures are correct, so the memo must state which denominator it uses.
Funds provide manager-led portfolio access, co-investments provide more control over each investment, and a combined portfolio can use both as institutional building blocks. The model follows the cited sources. The legal documents and the investor’s circumstances determine the actual outcome.
Fund Versus Co-Investment Choice
Funds and co-investments can serve different, equally deliberate roles in a large venture portfolio.
View chart data and assumptions
| Option | Role | When it may fit |
|---|---|---|
| Fund | Builds a portfolio selected by the manager across a portfolio. | When delegated selection and reserve management are priorities. |
| Co-investment | Adds precise exposure to a specific company or transaction. | When the LP wants conviction, sizing control, and strategic access. |
| Combination | Uses both routes within one portfolio structure. | When a diversified portfolio and deal-specific choice are both valuable. |
How Fund and Co-Investment Exposure Differ
| Dimension | Fund Investment | Co-Investment |
|---|---|---|
| Diversification | Exposure to multiple companies within one vehicle. | Exposure to one company or a small number of selected companies. |
| Primary Review | Manager, strategy, allocation mix, and terms. | Company, price, security, sponsor, and fit with the rest of the portfolio. |
| Diligence Workload | Heavy before manager selection, lower per company afterward. | Heavy per transaction, often under a compressed timetable. |
| Liquidity | Long-dated fund interest with restricted transfers. | Long-dated company or SPV interest with single-company exit dependency. |
Specificity Improves the Questions
Once the company is identified, the LP can test the entry price and the exact security. A look-through check will show whether the business already appears in an underlying fund. This turns manager-level confidence into a transaction decision.
- Known asset: Current operating, financing, and ownership information can be reviewed at the decision date.
- Specific security: The investor can examine the share class, preferences, transfer restrictions, and vehicle terms.
- A focused investment: The position can add or limit exposure by sector, stage, geography, business model, or existing look-through holdings.
- Explicit entry price: Valuation can be tested against company quality, financing needs, public comparables, and realistic exit outcomes.
Split a $50 million co-investment allocation equally across 5 companies and each begins at $10 million, or 20% of the allocation. Adding a sixth position of the same size requires more capital or a smaller holding elsewhere.
The visibility comes with work. A sponsor or administrator can coordinate the process, but the LP still needs enough information to understand and monitor every position.
Size the Company Inside the Whole Portfolio
Twenty equally sized companies inside a fund begin at 5% each. A standalone co-investment begins at 100% of its own vehicle. One company failure therefore has a very different effect before follow-on capital is considered.
A fund spreads company risk across a portfolio. A co-investment leaves the investor much more dependent on the selected business.
- Fund investments: Capital is spread across multiple companies. Diversification spreads venture risk, so one company failure generally represents only part of the fund's cost basis.
- Co-investment exposure: Capital is concentrated in one company. This can support a carefully selected view or increase exposure to a theme, but company-specific outcomes become more consequential.
Prepare the Review Before the Deadline
A co-investment may allow only 10 business days for review, while the exposure may remain illiquid for years. Goodwin describes a range of 8 to 12 years for a typical closed-end private fund. The deadline is short and the consequences are long, so the essential review process needs to exist before the materials arrive.
The team must run two linked assessments. One tests the sponsor’s incentives and allocation practices; the other tests the company and security.
- Fund diligence: Sourcing advantage, decision quality, team stability, reserve strategy, entry judgment, governance, conflicts, and alignment.
- Sponsor diligence: The lead investor's role, incentives, allocation practices, and ongoing support.
- Company diligence: Business quality, price, security, financing needs, and fit within the investor's portfolio.
Investment and legal reviewers should know their roles before the first opportunity. Tax and operational work needs an owner too. Otherwise the LP either misses the allocation or compresses diligence until it becomes unreliable.
The co-investment evaluation memo template records who will review the company, sponsor, terms and effect on the wider portfolio.
Compare the Complete Economics
Carta reports that 2% management fees and 20% carry remain the median venture-fund structure. In a simplified $10 million investment that doubles before fees, the profit is $10 million and 20% carry removes $2 million.
A co-investment may cost less, but the answer depends on its full structure. Sponsor carry and vehicle expenses should be combined with the LP’s legal and monitoring cost.
- Management fee and carry: Some opportunities reduce or remove these charges.
- SPV economics: Other structures include an upfront fee, administration cost, transaction expense, or SPV-level carry.
- Investor-level costs: Legal, tax, custody, reporting, and monitoring expenses may sit outside the vehicle.
- Allocation size: Small positions can become uneconomic when fixed costs are high relative to invested capital.
Each Invitation Still Needs a Sizing Decision
Fund access is normally settled during fundraising. Co-investments arrive intermittently, and receiving a data room does not guarantee the LP a cheque. The final amount depends on how much capital remains after the lead and the company’s preferred investors are accommodated.
When capacity is scarce, the sponsor also decides how to divide it among eligible LPs. The programme should be prepared for the approved investment amount to shrink before closing.
- How much outside capital the company is raising.
- What the lead investor can commit from its main vehicle.
- Which investors the company wants on its capitalization table.
- How the sponsor allocates limited capacity among LPs and other participants.
The reverse problem also occurs. Several credible opportunities may arrive together, making staff time and risk capacity scarce even when cash is available. A prioritisation rule keeps arrival order from deciding which opportunity receives capital.
Ask Why This Capacity Exists
A sound memo should explain why the company is attractive and why the sponsor is offering this allocation. A large outside pool may simply reflect a financing round that exceeds the lead fund’s capacity. In other cases, it reveals an exposure limit or weaker demand that deserves scrutiny.
- Benign explanations: The round may exceed the lead fund's capacity, or the company may want additional long-duration investors.
- Points to confirm: The lead's exposure limits, the company's financing plan, and whether the offered terms match the sponsor's position.
Useful review questions include:
- Is the sponsor investing from its main fund on the same terms?
- How is capacity divided when demand exceeds supply?
- Is the same allocation policy applied consistently across transactions?
- What help can the company expect if conditions deteriorate?
Follow the Information Through the Vehicle
A fund centralises reporting through the manager. An SPV adds another link between company information and the LP. A capable administrator can coordinate reports and tax documents, but the legal right to receive information must still be confirmed.
- Information rights: Reporting access depends on the transaction documents.
- Fund transfers: Selling a fund interest may require GP consent.
- Company-level liquidity: A co-investment depends on the financing and exit path of one company.
Neither route provides dependable liquidity. Model a delayed exit and a weak financing environment alongside the target case, then decide who can approve follow-on capital.
Decide When Each Structure Is Useful
- A fund may fit: The investor wants diversified exposure, delegated reserve and monitoring decisions, and access to the GP's broader portfolio.
- A co-investment may fit: The investor wants an investment in a specific company and can combine internal judgment with sponsor, adviser, legal, and administrative support.
- A combined approach may fit: Funds and co-investments can work together when each has a clear purpose in the portfolio.
Whatever the mix, keep one look-through view of company and sponsor exposure. Add the relevant stage and financing risk, then connect every position to its expected liquidity path.
CalPERS: fund commitments and co-investments in the same program
A CalPERS activity report shows how one LP can use several private-market structures at the same time. Its November 2023 list included a pooled fund commitment, a company-specific co-investment, and a secondary transaction.
For the pooled route, B Capital Opportunities Fund II provided delegated exposure.
By contrast, the separate Coefficient Capital co-investment created a specific transaction exposure.
A third structure appeared in B Capital Global Growth III, which was recorded as a secondary transaction.
The three entries belong to one LP portfolio, but they create different decisions. Each structure needs its own approval process, concentration limit, fee analysis, and monitoring plan. The report does not disclose the underlying company economics, so it cannot establish relative performance.

Frequently Asked Questions
Which is usually more diversified: a venture fund or a co-investment?
A diversified fund normally spreads capital across more companies. A co-investment gives the LP greater visibility into one business, which also makes that company more consequential to the result.
Are co-investments always cheaper than fund investments?
Reduced management fees can be offset by SPV expenses or sponsor carry. The comparison therefore needs the complete economics, including the LP’s own review and monitoring cost.
