Why Deal Limits Matter Before an Invitation Arrives
Co-investments can lower fees and add to a company the LP likes. They can also put too much risk in one place. An agreed budget and position limits give the LP a basis for judging each invitation, including reasons to decline when the deadline is short.
Later-stage transactions can also absorb large institutional cheques. Carta's tender-offer data reported a median size of $27.6 million for Series C or later companies in the first half of 2025. The figure is a measure of transaction scale. It shows how easily one deal can become material to an LP portfolio.
Underwriting Comes Before Fee Savings
Lower fees and carry can improve the return on a good investment, but they cannot rescue a weak business or an excessive entry price. The LP still needs a sound company case and a clear reason to hold the position in the wider portfolio.
A company's total weight includes stakes already held through funds. Limits by company and sponsor, and sometimes sector or stage, show how much room remains before a popular deal puts pressure on the budget.
| Exposure | How it grows | What to measure |
|---|---|---|
| Company | Direct cheque plus look-through fund ownership | Total value in the same company |
| Sponsor | Fund commitment plus several co-investments | All capital tied to the manager group |
| Sector | Opportunities arrive from the same market theme | Direct and fund-level sector exposure |
| Vintage | Many deals close during one active market | Entry-year value and unfunded needs |
A Large Allocation Needs an Explanation
The LP may receive a small piece of a highly sought-after company and a much larger share when a sponsor needs outside money. Size alone says little about quality. The reason for that spare capacity and the lead fund's retained stake help explain the offer.
Investing “alongside” a sponsor can still mean different fees or weaker rights. The sponsor's own security and terms provide a reference for how closely the two positions align.
The Annual Budget Is a Ceiling
An unused budget can preserve capital when available deals fail the investment criteria. Pressure to spend it for fee savings can pull the LP toward weaker companies.
- Company limit: Direct holdings and stakes through funds contribute to the same total risk.
- Sponsor limit: Funds, SPVs and co-investments led by the same firm all add to the LP's dependence on that sponsor.
- Independent review: Company evidence gives the LP a basis for testing the sponsor's investment case.
- Follow-on capacity: Money reserved for later funding affects whether the LP can support the stake after closing.
- Full economics: Vehicle expenses and carry reduce what the LP receives from the company outcome.
Co-investing adds selected company stakes to a broader programme. The sponsor's pipeline supplies opportunities, while the LP's own portfolio needs determine which fit. Those are separate roles in shaping the allocation.
How Many Company Positions Does the Allocation Create?
In a $100 million venture portfolio, co-investment targets of 0%, 10% and 30% equal $0, $10 million and $30 million. The policy becomes concrete only after the LP chooses a cheque size and sees how many companies the allocation can hold.
A $30 million allocation divided into $10 million cheques contains only 3 companies. That concentration is easy to reach when later-stage transactions are large; Carta reported a $27.6 million median tender size for Series C-or-later companies in the first half of 2025.
With only three companies, one result can dominate the allocation. If one $10 million position returns 3.0x, it produces $30 million and returns the original allocation before the other 2 outcomes are known. A loss in that company has an equally disproportionate effect.

A Planned Co-Investment Allocation
A set co-investment allocation can lower fees, but the portfolio still needs enough companies and clear selection rules.

What Access Lets the LP Understand
An invitation gives the LP a chance to assess a company rather than settling the decision. Knowing the sponsor and price provides context. Vehicle costs, reporting rights, transfer limits and future funding rules explain more of the position on offer.
Drift Appears Between the Deals
Each approval may look modest in isolation. Several deals can still share one sponsor or financing environment, and the same company may already sit inside a fund. The resulting economic position can become much larger than anything the committee approved at one time.
A co-investment and related fund stakes add to the same exposure, while later funding can increase it again. A shared record of both connects each new deal to the agreed limits. With that context in place, the committee can make a faster decision without losing sight of the total risk.
Frequently Asked Questions
Can co-investments improve net returns?
Good selection and a sound price can combine with lower costs to improve net returns. Position size still affects the risk: one low-fee holding can dominate the whole allocation.
What should LPs confirm before accepting an allocation?
The reason capacity is available and the stake retained by the sponsor help explain its incentives. Differences between the securities affect the buyer's rights, while total company exposure shows how much risk the allocation would add.
