I own a startup that is user-based. We are close to finishing the building of the prototype so therefore it has no users, no revenues, nor any investment.
I have 4 unpaid co-op students working full-time for a term. In order to encourage them and value their work, I would like to share equity with them, preferably equities that expire after 1 year since their co-op ends after 3 months and they probably won't be at the start-up anymore.
We will be launching soon and will probably generate some but not much revenue. The idea is to provide
expirable equities for them to split the revenues generated within a year.
I did some research and could not find anything such as
expirable equities. Does something like this exist in financial terms? If so, what would it be called? What percentage do you think I should give them?
