How to use this app
Pick one dashboard, edit assumptions, read the outputs, then export the current tab when you need a memo-ready snapshot.
1. Secondary Deals
Use this when buying or arranging a secondary/SPV position. It compares two fee structures, checks premium/discount versus a round price, allocates fees by payer, and computes dated cash-flow XIRR.
- Best for secondaries, SPVs, tender access, pre-IPO blocks, and fee-stack comparisons.
- Key outputs: total fees, net proceeds, net multiple, XIRR, payer burden, premium/discount.
- Watch-outs: wrong fee allocation totals, stale round price, unrealistic hold period, and SPV overhead eating return.
2. Primary Deals
Use this for new primary rounds: pre-seed, seed, and Series A. It models valuation, ownership, option-pool expansion, pro-rata needs, liquidation preference behavior, dilution, and exit-return sensitivity.
- Best for deciding whether a priced round or SAFE-like deal is directionally attractive.
- Key outputs: ownership, round dilution, price discipline, reserve need, preference breakpoint, exit MOIC, implied fund-return contribution.
- Watch-outs: small ownership with big check, too much dilution, investor-unfriendly terms, no pro-rata rights, and high exit requirement.
3. Follow-On Decision
Use this when an existing portfolio company raises again. Compare skip, pro rata, super pro rata, and secondary purchase paths, then rank the opportunity against portfolio constraints.
- Best for reserve allocation and ownership-defense decisions.
- Key outputs: check required, ownership, blended cost, incremental MOIC/IRR, fund concentration, score, and recommendation.
- Watch-outs: anchoring to the old investment, over-concentration, weak incremental returns, and cheaper secondary shares with inferior rights.
4. Fund Math
Use this before pitching LPs or changing strategy. It converts fund size into management fees, investable capital, initial checks, reserves, ownership targets, stage allocation, follow-on budget, and required power-law outcomes.
- Best for emerging managers building or defending portfolio construction.
- Key outputs: number of investments by stage, check sizing, reserve ratio, fees, GP commit, deployment pace, gross/net TVPI, DPI placeholder, and winner requirement.
- Watch-outs: under-reserving, too many tiny checks, ownership too low to return the fund, fees too low to operate, and a target TVPI that requires fantasy exits.
Operating rules
The math is intentionally fast and practical, not a substitute for legal, tax, accounting, or investment diligence.

Structure comparison
Model two fee stacks side by side.
Structure A
Structure B
SPV overhead
Direct cost assumptions for the vehicle.
Round vs secondary pricing
Check whether the trade is at a premium or discount.
Fee allocation splits
How the cost burden is allocated across investor, sponsor, and client.
Dated cash flows
Add interim distributions or reimbursements. XIRR recalculates automatically.

Primary round inputs
Fast pre-seed, seed, and Series A deal math. Editable assumptions, instant outputs.
Deal decision signal
Directional verdict from the inputs.
Terms and sponsor economics
Persisted boxes from the secondary dashboard where they make sense: fees, carry, hurdle, allocation mindset, and dated economics.
Valuation and ownership
What the instrument buys.
Fund Return Math
What the deal needs to matter at fund level.
Do not approve on company quality alone.
Great company ≠ great fund investment.
Term-sheet stress checks
Plain-English flags that matter in early-stage deals.

Pro-rata / reserve need
Simple follow-on planning for ownership defense.

Follow-on position and round
Re-underwrite the company as a new investment, then compare every ownership path.
Portfolio constraints
Force the deal to compete for scarce fund capital.
Scenario comparison
Total-position and incremental economics are shown separately so an old winner cannot hide a weak new check.

Fund-level inputs
Emerging-manager construction math LPs will dig into: fund size, fees, GP commit, investable capital, deployment, reserves, ownership, and return power law.
LP-readiness signal
Construction sanity check.
Stage allocation and check sizing
Edit each stage. Percentages should total 100%. This is intentionally separate from the Primary Deals calculator.

What is actually available to invest.
Portfolio construction
Companies, reserves, graduation, and deployment pressure.
