In this situation, what's a fair equity share?
bayareaguy: These things are never simple but a fair distribution should take into account the risk each person took and the value of their contribution.  For example if they worked twice as long as you and they took twice the risk you did then it would be difficult for you to justify more than a 1/9 stake.If they were stuck before you got there and you played an important part in getting a 3-person company to some measure of profitability then you probably deserve closer to a double-digit percentage.A board seat is probably out of the question at this point but I'd recommend you negotiate for the same class of shares and vesting/acceleration options that your co-founders get.
