Fund managers
How can a seed venture fund make its portfolio model understandable to LPs?
a seed venture fund: Make the portfolio model understandable through a capital bridge and explicit operating assumptions.
Make the portfolio model understandable through a capital bridge and explicit operating assumptions. Fund size, costs, initial checks, reserves, ownership, and company count must fit together. A balanced model still requires access, judgment, and capacity to execute.
Start with the decision
Show a base case and a smaller-close or larger-check case. Label every assumption and explain which decisions change. Keep formal fee treatment and actual fund terms subject to the governing documents and qualified advisers.
The illustrative scenario
This is an educational workbook. The company or fund and all numerical inputs below are fictional. They are not ADIN results, customer claims, market benchmarks, or a forecast.
The fictional manager targets companies with an initial customer base and plans to join priced rounds. It uses larger initial checks than the pre-seed example and expects a smaller portfolio. Co-investor access is part of the thesis.
An attractive round does not prove allocation access or consistent decision quality. Verify what the manager could actually invest, the price paid, and the ownership maintained.
Reconcile the portfolio plan with its capital budget
This fictional model starts with $60,000,000.00 of commitments and sets aside $10,000,000.00 for modeled lifecycle costs and $20,000,000.00 for follow-ons. That leaves $30,000,000.00 for initial checks. A target of 25 investments at $1,200,000.00 requires $30,000,000.00 before any other unmodeled uses.
The cost amount is a hypothetical budget, not a quoted fee or an industry norm. Actual fees, expense allocation, offsets, fund term, investment authority, and distributions depend on the governing arrangements. A balanced budget does not establish that the manager can obtain the allocations, ownership, or results assumed in the strategy.
Compare the strategy with actual check sizes and capacity. Identify whether the model relies on ownership or access that has not yet been demonstrated. Reduce the final close or increase the initial check and identify what changes first: company count, reserves, operating resources, or the strategy itself. For this article's question, use the resulting constraint to request the specific evidence or document provision rather than treating the spreadsheet as the decision.
| Item | Illustration |
|---|---|
| Fictional fund commitments | $60,000,000.00 |
| Modeled lifecycle costs | $10,000,000.00 |
| Modeled follow-on reserves | $20,000,000.00 |
| Available for initial checks in this model | $30,000,000.00 |
| Target initial investments / check size | 25 / $1,200,000.00 |
| Initial-investment capital required | $30,000,000.00 |
Use this worksheet
Answer the questions with a source, date, owner, and next action. Mark an unknown as unknown. Use public or permissioned information and involve a qualified specialist when a question requires expertise beyond the team’s competence.
- What capital is investable?
- How many initial checks fit?
- What is reserved?
- What ownership is assumed?
- What changes in an adverse scenario?
Questions specific to this scenario
- Which allocations were actually obtained?
- What changes when round sizes rise?
- How are reserves prioritized?
Request executed investment records where available, a complete portfolio schedule, reserve assumptions, and references about the manager's role. Keep proposed deals separate from completed investments.
A concrete next test
Select one completed investment and one opportunity where the manager could not obtain the desired allocation. Ask how access, price, and ownership affected the decision. Include both examples when evaluating whether the proposed check sizes and company count are executable.
Interpret the result
The model should expose dependencies, not imply forecast precision. LPs need to see where a target requires unproven allocation access, favorable pricing, or operating support beyond the manager's demonstrated capacity.
Compare the strategy with actual check sizes and capacity. Identify whether the model relies on ownership or access that has not yet been demonstrated.
