§FAQ
Option pool FAQ
When investors require an unallocated employee option pool to be in place before a round, they typically size the pool as a percentage of post-money fully diluted but place the pool in the pre-money valuation. That means founders bear the entire pool dilution while the investor's ownership is unaffected. The same 10% pool placed pre-money costs founders roughly 3 to 8 percentage points more than the same pool placed post-money.
