But it's not all that great. Patreon is not publicly traded, so it seems likely that exercising any options will require cash up front, plus it will immediately trigger taxable compensation (income tax plus FICA). And how will the FMV be determined, if there is no public market trading? (ans.: usually just some number voted on by the board). It may well be that the options are never worth anything even after the extended period.
It is clear that these are not ISOs (statutory options), because statutory options by law only allow up to 3 months to exercise after employment ends.
