Estimate the impact of a funding round on your cap table: post-money, investor ownership, option pool, founder dilution and negotiation points.
Calculate post-money and investor ownership from pre-money valuation.
Measure founder dilution with a target post-round option pool.
Spot cap table alerts before negotiation.
A funding round changes ownership, future rights, governance and hiring capacity. A pre-money valuation may look attractive, but option pools, preferences and future rounds often change the economics.
Post-money valuation is pre-money valuation plus new money invested. Investor ownership is calculated from that base, but documents may create additional economic effects.
An investor-requested option pool may create extra dilution for founders, especially if it must be created before or during the round.
The simulator covers the basic mechanics. Negotiation must also include liquidation preference, anti-dilution, governance and information rights.
A useful cap table must match articles, shareholder agreements, existing instruments and commitments to employees or advisors.
We connect dilution to the cash actually financed: runway, margin, hiring, debt, working capital and the next round. A round that is too small or too dilutive can be as damaging as an unrealistic valuation.
A founder may accept a decent valuation while underestimating the pool, convertibles, liquidation preference or next round. Real dilution then appears too late.
In a simple model, investor ownership equals the amount invested divided by post-money valuation. The shareholder agreement can then change real economics.
Yes, when it increases reserved instruments. The impact depends on pool size, timing and whether the calculation is fully diluted.
Share rights, option pools, convertibles and investor protections can materially change future economics.
No. It gives a financial estimate. The official cap table must match corporate documents and share registers.
Before signing the current round. Acceptable dilution today can become problematic if another seed, Series A or bridge is needed soon.
Updated on 4 May 2026. The simulator does not replace a term sheet or legal cap table review.
We can review your cap table, runway and dilution scenarios before a term sheet or investor negotiation.
