Venture Capital Portfolio Construction for LPs
HarbourVest's portfolio-efficiency article shows how the way an investor enters an asset class can affect risk, return, and cash flow. The same asset class can behave differently depending on whether the investor uses primaries, secondaries, or co-investments. An LP should consider managers, stages, vintages, and ways to invest as parts of one portfolio.
HarbourVest models allocations at 0%, 10%, 20%, and 30% in its portfolio-efficiency example. Venture LPs can use the same type of comparison when deciding how much to allocate by stage and investment type.
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. |
LP Construction Happens Across Managers and Vintages
LP portfolio construction combines manager selection, vintage pacing, stage, geography, way to invest, commitment size, and liquidity into one venture programme. It is different from the way a GP builds one fund of startup investments. The LP's task is to decide which managers and vehicles should receive capital, when commitments should be made, and how the whole set behaves alongside the rest of the portfolio.
The Main Building Blocks
| Choice | What it can add | What it can cost |
|---|---|---|
| More managers | Less dependence on one team | Smaller commitments and more oversight |
| More vintages | Spread 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 |
Begin With the Portfolio's Need
The institution should state why venture belongs. The aim may be long-term growth, access to private technology, diversification from public markets, or a source of returns that can accept illiquidity. The goal changes which managers and stages fit. A programme built for early innovation should not quietly drift into late-stage funds simply because those managers can accept larger cheques.
Use Pacing to Build, Not Chase
Commitments should be spread across years. This reduces the chance that the entire programme enters at one valuation level and creates room to learn from early relationships. Annual pacing should include new managers, re-ups, and expected co-investments. It should also slow when the programme is over target or liquidity is under pressure.
Suppose an LP is building a $100 million venture programme over three years. It might commit $30 million in the first year, $30 million in the second, and $20 million in the third while keeping $20 million available for selected co-investments, secondaries, or a later vintage. The commitments will not be called immediately, but successor funds may begin raising before older managers return cash.
The pacing plan should therefore show more than annual commitment totals. It should include expected re-ups, remaining unfunded capital, room for new managers, and a case in which distributions arrive later than expected. Otherwise a sensible three-year target can become an accidental concentration in whichever managers happen to be fundraising first.
Measure Concentration Several Ways
Manager percentage is only the first view. LPs should also measure exposure to a management firm across successor funds, look-through company overlap, stage, sector, geography, and the top five positions by NAV. Co-investments can make company concentration rise quickly even when fund commitments look diversified.
Keep Liquidity in the Same Model
Unfunded commitments, expected calls, fees, and distributions belong in the construction plan. The institution should test a period with weak public markets and few exits. A portfolio that produces an attractive expected return but forces asset sales during a downturn is not well built.
What the Investment Committee Should Approve
- Target range: Venture as a share of the full portfolio.
- Annual pacing: New commitments by year and way to invest.
- Concentration limits: Manager, company, stage, and vintage.
- Liquidity plan: Sources for calls under a hard case.
- When to re-up, resize, pause, or replace a manager.
Good LP construction makes every commitment part of a programme. It prevents a collection of attractive funds from becoming an accidental portfolio.
Build the Portfolio in Layers
One possible approach looks like this. An LP could place 40% with established or core funds, 20% with emerging or specialist managers, 30% in co-investments or SPVs, and 10% in secondaries or other liquidity-oriented opportunities. The $30 million set aside for individual transactions supports 3 initial $10 million positions before follow-ons.
NVCA's 2025 stage data shows that later VC and venture growth represented much larger dollar pools than seed, which affects how large LP commitments can be deployed.
Control Concentration Across Dimensions
If the top 5 managers represent 50% of NAV, the portfolio may be more concentrated than the total number of manager names suggests.
A sample $100 million LP venture allocation allocates $40 million to core funds, $20 million to specialist managers, $30 million to co-investments or SPVs, and $10 million to secondaries.
LP Venture Portfolio Layers
An LP can combine core funds, specialist managers, co-investments, SPVs, and secondaries in one portfolio.

| 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?
The LP chooses exposures, not only companies: The LP allocates across managers, vintages, stages, geographies, and structures.
When can co-investments or SPVs form a real allocation?
When access and administration are institutionalized: A material deal-specific allocation can work when the LP has a clear sourcing relationship, repeatable diligence, $10 million-or-larger position sizing, reserves, reporting, and look-through portfolio controls.
