How to deal a Voluntary Exit from Startup

We are a 3 people company running from last 3+ years, we have our share holding agreement with equal share for each of us but no specific vesting clauses. Now i am planning to quit for personal reasons[ not fired ] . I would like to get money for the shares at the time of quitting, but company wants to differ it to a future date whenever they get an external funding citing lack of money now. What is the best way to handle this situation. Can i actually force them to pay at the time of exit or wait till external fund is raised

It all depends on the exact terms of your agreement of course, but your issues are the same as most founders in your situation:

1. Your value your work and believe the company has potential

2. But the startup is still cash-poor since it's not making money

3. So no one can buy your shares at a price you'd like today

Frankly, the only sane option is to wait and sell your shares later, but relinquish control to the remaining two founders. Support them passively. Understand that a fair deal should have you lose some benefits since you are not actively contributing anymore.
