Round Pre-MoneyTerm That WinsEffective Valuation Ownership After RoundValue at ExitMultiple
Assumes a standard YC post-money SAFE: ownership at conversion = investment ÷ min(cap, discounted pre-money), then diluted by the new round (new money ÷ post-money) and by your further-dilution estimate. Ignores option-pool top-ups, pro-rata participation, multiple SAFE stacking, and liquidation preferences. A modeling aid, not investment or legal advice.
