Most successful founders retain 15-30% at exit. The value matters more than the percentage.
Founder dilution is the gradual reduction in ownership that occurs with each funding round. It is an inevitable part of venture-backed growth, but understanding its mechanics helps founders make informed decisions.
The math is multiplicative, not additive. If you start at 100% and dilute 20% in a seed round, you own 80%. If Series A then dilutes 25%, your effective ownership becomes 80% times 75%, equalling 60%.
Most successful venture-backed founders own 15-30% at IPO or exit. What matters is not the percentage but the value: 15% of a billion-euro company is worth far more than 90% of a company that never scaled.
