How the financing math works
Post-money valuation = pre-money valuation + investment. Investor ownership is investment divided by post-money valuation. The implied share price is pre-money valuation divided by the fully diluted shares outstanding before the round.
This simplified model assumes one financing price and does not include option-pool top-ups, SAFEs, convertible notes, multiple share classes, taxes or transaction costs. Use signed financing documents and professional advice for actual transactions.
