At the moment, my co-founders and I are working on our startup part-time. We're in the process of figuring out how many shares to allocate to each person.
If one of us quits their full-time job to work on the startup full-time, how should that affect things? For example:
- Should that person be given additional shares? If yes, how do we determine how many?
- Should we consider that person's time as cash invested in the startup?
If additional shares are granted to that person but we don't known when the other co-founders will work on the startup full-time, how can we be sure that any share allocation decided upon now is "fair" X months in the future?
