Why it matters

Investors want founders to retain meaningful equity — typically above 40% at early stage — to stay motivated and fundable. Where the dilution actually lands depends on details founders often miss: pre vs post-money, SAFEs converting, and whether the option pool comes out of your slice or everyone's.
