Understanding Startup Cap Table Math & Option Pools

Every venture round changes both the percentage ownership and the dollar value of shares. When pricing an equity round, founders must watch two critical variables:

1. Effective Pre-Money Valuation

When a VC insists on an unallocated 15% pre-money option pool, the true pre-money valuation of existing founder shares is reduced by exactly 15%, lowering the price per share paid by the investor.

2. Percentage vs. Dollar Value

Dilution reduces your ownership percentage, but increases your net worth if the valuation grows. Owning 60% of a $15M company ($9M) is vastly superior to owning 100% of a $1M company.
