I fully agree. You must be compensated. It does not have to be cash. Equity works, too. But he(?) needs to be sticking to whatever compensation agreement is in place. That is a deal-breaker.

Many of the other issues are going to be a case-by-case basis. Does he know he is being unreasonable? Can you call him on it, and will the behavior change? Does he apologize and correct himself when called on it, or does he defend his actions?

In some ways, there is an analogy between working with the CEO of a startup and a marriage. There will be problems. There will be bad times. The question is whether or not both sides are committed to the relationship, willing to hear the other's side, empathize with it, and make the changes necessary to improve it. In most cases, this is just a job, the answer will be "No" and you should quit.

Not open to negative feedback. Any conversation about this is going to blow up. Some people have tried and failed. Some have quit.

I detailed a bit more in my other rant, but if you want to stay or get what you're owed, you're going to have to risk the conflict.

The only way to not have conflict about this is to leave and say nothing. If you think he won't allow you to leave at all without conflict, then you might as well choose the conflict with the better possible rewards.

You shouldn't let things continue. But whether or not you're going to attempt to point out the problem is up to you.
