I've been thinking about a model where a startup/early-stage company would give NO shares on hiring, but instead slightly more salary and a generous (15% discount?) stock purchase program. That people feel less obligated to negotiate and employees get more flexible vesting (month-to-month). I have no idea how that would work with pre-IPO companies, tax implications, etc but it feels more fair to me. On a similar note, I wish there were better ways to prevent dilution among early-stage employees. They ostensibly generated the value that investors are buying, so why must they lose out on every funding round? Of course, employees could negotiate for more options on every round but not everyone will do so.
