What is the difference between the following two compensation strategies: (1) You get 100 options, that vest at 1/4 after one year and 1/4 after every following year. (2) You don't get any options now. You will get 25 options, which can be exercised immediately (or whatever the equivalent status is of vested options), after one year. And similarly three more times.
I assume it's 30% (a) taxes, 65% (b) psychology, and 5% (c) something that happens if there's an IPO or other exciting event?
In short, where can I read about what startup compensation is, why it is the way it is, and the math behind how much it's worth?
