Co-investment capital reaches one named company through a sponsor, fund, or dedicated vehicle. Relationship flow only. Paths do not represent capital allocations or transaction probabilities.
Co-Investment Structure
Co-investment capital reaches one named company through a sponsor, fund, or dedicated vehicle.

| Direct | Company | Investor owns shares or interests more directly. |
| SPV | Vehicle | Vehicle aggregates investors into one position. |
| Fund sidecar | Rights | Opportunity sits near a fund relationship. |
Key Takeaways
- A co-investment is company-level exposure: The investor evaluates a named business and transaction rather than committing to a blind-pool portfolio.
- The sponsor's role can vary: It may provide access and administration, or lead diligence, negotiate rights, coordinate closing, and report after investment.
- Legal structure changes the investor's position: Direct ownership, an SPV interest, and a fund sidecar can differ in rights, control, information, tax treatment, and transferability.
- Concentration requires deliberate sizing: Look through existing fund and SPV holdings, and plan for possible follow-on capital.
A Public Example
ILPA's co-investment guidance is useful because it focuses on allocation, expenses, and disclosure rather than treating co-investment access as a simple perk.
- The economics can differ: Co-investments may carry lower fees, different expense treatment, and different governance rights than a blind-pool fund.
- The practical lesson: Investors should ask why this deal is being offered, who else received access, and how the terms compare with the main fund.
- Useful number: A conventional venture fund is often summarized as 2 and 20; co-investments may change that fee profile, but the full expense stack still matters.
How the Structure Works
Round example: In a $100 million financing, a lead investor taking $60 million may syndicate $40 million. A $5 million co-investment would represent 12.5% of that syndication pool.
A fund delegates future company selection to a manager. A co-investment presents one named company or transaction for review.
The investment may be made through:
- Direct ownership: The investor holds company shares or another security more directly.
- SPV: A dedicated vehicle aggregates several investors into one company position.
- Fund sidecar: A related vehicle sits alongside a manager's principal fund.
The sponsor's role may include:
- Access and administration: Organizing the opportunity and maintaining the vehicle.
- Diligence: Leading analysis of the company and transaction.
- Negotiation and closing: Securing allocation, rights, and documentation.
- Ongoing reporting: Providing information after the investment closes.
Voting authority, information flow, tax reporting, transfer rights, and follow-on decision-making may differ across the three structures. The governing documents, rather than the marketing summary, determine the investor's actual position.
ILPA's Principles 3.0 identifies allocation, conflicts, expenses, and co-investment policies as matters LPs should understand clearly.
Why Investors Consider Co-Investments
Economic comparison: A fund with 2% management fees and 20% carry has different economics from a co-investment offered at 0% management fee and 10% carry. On $1 million of profit, carry alone differs by $100,000.
- Transaction visibility: The investor can review the company, price, security, and timing before participating.
- Targeted exposure: The position can add weight to a sector, geography, or stage the investor understands well.
- Known-company exposure: An LP may increase its position in a company already held indirectly through a manager.
Greater visibility does not create diversification. The result still depends heavily on one company's financing path and exit.
Why Is the Allocation Available?
Vehicle-size context: In Carta's sample of large SPVs, the 2023 median size was $22.6 million, up from $15.2 million in 2019. A large allocation can still reflect syndication mechanics rather than quality.
Availability is part of the underwriting.
- Larger round: The financing may exceed the lead investor's capacity.
- Shareholder strategy: The company may want another long-duration or strategically relevant investor.
- LP relationship: The manager may reserve some capacity for selected fund investors.
- Portfolio limits: The sponsor may already have substantial exposure.
- Weak conviction or demand: The transaction may be difficult to complete or less attractive to the lead.
Ask whether the sponsor invests its own capital, holds the same security, and applies a clear allocation policy when demand exceeds supply. Fees and carry may also affect the sponsor's incentive.
What Requires Diligence
Review-window test: A 10-business-day decision on an asset held for 10 years compresses roughly 365 days of potential ownership into each diligence day. Governance should be designed before the opportunity arrives.
The diligence burden is more company-specific than in a diversified fund.
- Business quality: Market, product, revenue, burn, financing needs, and competitive position.
- Shareholder context: Existing investors, their incentives, and the company's financing history.
- Security package: Preference, seniority, conversion, voting, information, and pro rata rights.
- Dilution: Option-pool changes and future rounds can reduce ownership.
- Liquidity: Identify plausible exit routes and timelines.
- Net economics: Model vehicle fees, expenses, and carry separately from the company-level return.
Reconcile the current capitalization table with the exact security being offered.
Portfolio Sizing and Follow-On Capital
Set position size using the investor's look-through exposure across funds, SPVs, direct holdings, sectors, and founders. A modest-looking SPV allocation may duplicate a company already held through several venture funds.
Decide the follow-on policy before the company needs more money:
- Reserve decision: Will the investor hold capital for future rounds?
- Vehicle control: Who decides whether an SPV participates again?
- Stress response: What happens if the company raises during a difficult market?
- Non-participation: How would dilution or loss of rights affect the position?
When It May Fit
- May fit: Investors that can evaluate single-company risk, tolerate illiquidity, and size the position within a broader portfolio.
- May not fit: Investors seeking diversification, predictable liquidity, or fully delegated decision-making.

CalPERS: a co-investment is recorded separately from its funds
CalPERS' March 2024 activity report listed pooled funds, co-investments, and a secondary transaction as distinct commitments even when they sat in the same private-equity program.
Coefficient Capital was identified specifically as a co-investment.
B Capital Opportunities Fund II was reported as a fund commitment.
B Capital Global Growth III was separately classified as a secondary transaction.
What it shows: The classification affects underwriting and monitoring. A co-investment is a specific transaction alongside a sponsor; it is not simply another drawdown from the blind-pool fund.

Frequently Asked Questions
Is a venture co-investment the same as a direct startup investment?
Short answer: Not always. A co-investment is typically made alongside a sponsor or lead investor and may be held directly or through an SPV, with the sponsor influencing access and administration.
Do venture co-investments always have lower fees?
Short answer: No. Economics vary by vehicle and sponsor. Investors should review management fees, carry, setup costs, administration, expenses, and any economics paid at another layer.
