Model founder dilution across seed and Series A funding rounds

Seed round dilution refers to the reduction in founders ownership when investors receive new shares for capital. Understanding dilution helps founders plan equity across multiple funding rounds.

💡

Tip: Minimise option pool top-ups before fundraising - pre-money pool refreshes dilute founders before the investment arrives.

Fun Fact

Average seed rounds dilute founders by 15-25%. By Series B, founders typically retain 40-60% collectively.
