How this is calculated
- Post-money valuation is pre-money plus the amount raised.
- Every existing holder is diluted by the same factor: pre-money divided by post-money.
- New investors own the raise divided by post-money.
- This models a clean priced round without pool top-ups or converting SAFEs; those make dilution worse and are worth modelling on the real table.
