A collection of good funds can still make a poor portfolio
Good venture managers can still combine into a poor portfolio. Their funds may own the same companies, stages and sectors or raise money in the same cycle. Those shared exposures connect their risks, timing and cash needs.
The programme needs a role for each commitment. Core funds can provide broad manager-led exposure. Specialists can add a distinct strategy, while co-investments and SPVs add selected company risk. Secondaries can reshape vintage exposure or shorten the expected duration.
HarbourVest's portfolio-efficiency article illustrates the broader principle: the route into an asset class affects risk, return, and cash flow. Venture is no different.
HarbourVest compares allocations of 0%, 10%, 20% and 30%. An LP can use the same steps to see when adding venture improves the programme and when it only repeats exposure the LP already owns.
A sample LP venture allocation shows forty percent core funds, twenty percent specialist managers, thirty percent co-investments or SPVs, and ten percent secondaries.
A Layered LP Venture Portfolio
The LP can combine manager-led funds with selected SPVs, co-investments, specialist managers, and secondaries inside one allocation.

| Portfolio segment | Share | How to read it |
|---|---|---|
| Core venture funds | 40% | Manager-led diversified company exposure. |
| Specialist managers | 20% | Focused strategy, sector, stage, or emerging-manager access. |
| Co-investments or SPVs | 30% | Selected company or transaction-level exposure. |
| Secondaries | 10% | Vintage shaping, liquidity access, or shorter-duration private exposure. |
The LP is constructing across relationships and time
A GP divides one fund among companies. The LP allocates across managers and then decides when to enter each relationship, how much to commit, and whether to add direct or secondary exposure around it. Those choices create one programme with a shared liquidity burden.
The institution's reason for owning venture shapes the portfolio. Moving from early innovation into later-stage funds solely because those funds can take larger cheques changes that purpose.
Every building block solves one problem and creates another
| Choice | What it can add | What it can cost |
|---|---|---|
| More managers | Less dependence on one team | Smaller commitments and more oversight |
| More vintages | Exposure across market cycles | Longer build period and ongoing re-ups |
| Earlier stage | Higher upside and earlier ownership | More losses, dilution, and longer holding periods |
| Growth stage | More operating evidence and nearer exits | Higher prices and public-market sensitivity |
| Co-investments | Company choice and lower fee load in some cases | Concentration and fast diligence |
| Secondaries | Later entry and possible earlier cash flow | Complex pricing and seller selection |
More managers reduce dependence on one team but create more oversight. Earlier-stage funds offer larger potential upside while increasing loss rates and duration. Co-investments may lower fee load, yet they also concentrate the programme in selected companies. The right mix is the one whose costs match the LP's objective and resources.
Commitments Across Fundraising Years
Commitments across vintage years reduce dependence on one pricing environment and give the LP time to learn. New managers, re-ups and co-investments all use the budget. When the programme is above target or cash is tight, a slower pace leaves more room to fund existing obligations.
Suppose an LP builds a $100 million programme over 3 years. It commits $30 million in each of the first 2 years and $20 million in the third. The final $20 million can support selected co-investments, secondaries, or a later vintage.
Funds call commitments over time, and successor funds may arrive before older ones return cash. Re-ups, unpaid commitments and delayed payouts therefore shape the schedule. Without that wider view, the managers raising first can come to dominate the programme.
The Holdings Beneath Fund Labels
An illustrative allocation places 40% with core funds and 20% with specialists. Co-investments or SPVs receive 30%, while secondaries receive the remaining 10%. On a $100 million programme, the $30 million transaction allocation supports 3 initial $10 million positions before follow-ons.
NVCA's 2025 stage data shows much larger dollar pools in later VC and venture growth than in seed. That market structure affects how easily a large LP cheque can be deployed without changing stage exposure.
If the top 5 managers represent 50% of NAV, the programme remains concentrated even when the manager list is long. Co-investments can push company concentration higher without changing the fund-level picture.
Successor funds may depend on the same management firm, and different funds may own the same company. Combined stage, sector, regional and position data reveal risks hidden by separate fund names.
Liquidity Is Part of Portfolio Construction
Unfunded commitments, calls, fees and distributions share the same cash pool. Weak public markets and few exits can strain it at once. An attractive expected venture return may still come with a forced sale of liquid assets at a poor time.
The target range and annual pace set the programme's scale. Manager and company limits constrain concentration, while a cash plan covers difficult markets. Re-up, reduction, pause and replacement rules explain how the programme responds as conditions change.
A sample $100 million LP venture allocation assigns $40 million to core funds and $20 million to specialist managers. Co-investments or SPVs receive $30 million. Secondaries receive the remaining $10 million.
LP Venture Portfolio Layers
An LP portfolio can use manager-led funds as its core. Specialist managers and selected company exposure can sit around it, with secondaries used for vintage or liquidity needs.
View layer assumptions
| Layer | Allocation | Role |
|---|---|---|
| Core venture funds | 40% | A portfolio selected by the manager. |
| Specialist or emerging managers | 20% | Focused access and distinct sourcing. |
| Co-investments or SPVs | 30% | Selected investments in specific companies. |
| Secondaries or liquidity tools | 10% | Vintage shaping and potential shorter-duration exposure. |
Frequently Asked Questions
How is LP construction different from GP construction?
A GP spreads one fund across companies. An LP spreads capital across managers and vintage years, then chooses the mix of stages and regions. Together, those choices determine what the programme ultimately owns.
When can co-investments or SPVs form a real allocation?
Deal-by-deal investing can work with reliable access and a repeatable diligence process. Positions of $10 million or more can create substantial follow-on demands. Combined holdings data and reporting reveal their place in the full portfolio.
