I'm curious to know how much you are really valuing your startup in terms of the
minimum $ it would take for you to give it up right now.
I realize all transactions are different, so I'm going to try to simplify it for you as much as possible. Suppose you net $X from the transaction, in your bank account, today. No other $ down the line.
Also, suppose you like the acquiring company, i.e. you think they won't mess it up. Suppose you get to do whatever you want after the acquisition (work on it, not work on it, consult, etc.). Suppose there is a non-compete structured in such as way as you can’t work on exactly the same thing for a while. And disregard any other liability--consider it worked into X.
