Conflict and leaving a startup

When people avoid conversation for honesty and clarity, you're bound to move on to better things.
The truth is, your value is your piece of the pie.

Lessons to be learned:

• Don't work with your boyfriend/girlfriend. 
• Don't say yes to equity - it's a lie and "thank you for your hardwork" doesn't pay my bills.
• Don't join a startup with 10% equity or less. Equal shares = equal responsibilities. 
• If you don't trust your co-founders, leave. 
• If you feel left out and you're not having fun, what's the point in staying and being miserable about it
• If you're already thinking about the next startup project in your head, you're probably wasting your time in the startup you're in.

And don't forget to bring all your contacts with you.

There are other contentions with aspects of diversity, but then if there are no contracts or systems in place, there is 'nothing'.
Legal implications are important in the beginning, but signing a document without trust is nothing. Business pre-nups need to be scoped and all the hurt and pain you're feeling now, is part of the lesson. Embrace it - and like the reason you became an entrepreneur in the first place, move on and start your own thing.
