One of the Sam Altman's advice in his blog[1] was to "grant options that are exercisable for 10 years from the grant date, which should cover nearly all cases".
This is due to when employees leave companies, they only have 90 days to exercise their vested options and they don't have the money to cover the strike price.
Is there any company that took this advice and changed their employees grant option policy?
