When negotiating, keep these baseline numbers in mind: founders typically sell 15-20% of the company in a seed round. Employee option pools generally consume 10-15% of the total equity, backed by
Carta's guide on sizing employee option pools.
Sample math.If your pre-money valuation is $8,000,000 and you raise $2,000,000, your post-money valuation becomes $10,000,000. The investors now own 20% of your company ($2M / $10M). If they also require a 10% post-money option pool created before the round closes, that equity comes entirely out of the founders' pockets, dropping your real pre-money valuation.
