Most founders focus on valuation during fundraising. Fewer pay close attention to how each financing round changes their long-term ownership.
According to Carta's 2026 data, the median founding team owns 56% at Seed, 36% after Series A, and only 23% by Series B. By Series C, founder ownership falls to around 16%.

Whether you're building your first startup or preparing for your next funding round, understanding your cap table can have a lasting impact on what you ultimately own.
