The per-role bands above are conventional planning ranges used for sizing a pool, not figures drawn from a named published dataset, so treat them as a starting point to argue with rather than a benchmark. What is measured: Carta puts the median employee option pool at 12.1% of fully diluted equity at seed, rising to 16.8% by Series C, at which point the pool is larger than the median founding team's combined stake of 16.1% (Founder Ownership Report 2026). Actual grants vary by location, hire seniority, and company maturity within stage.
