How long do you think the company will survive without you? Act accordingly. The ceo is trying to get someone in at a lower cost to take-over your work. Do you think it will work before the site crashes or a hard bug arises? Inform the investor and take the money out, be honest to him. He will not like this. He will wait to invest again ( or inform other investors), untill the CEO has proven he can do it, which he probably won't. Ask the cofounder to take on a loan if that's possible ( perhaps less than the equity), he thinks you are disposable. Get out and don't help out. Have the same contract with you as you do now, but take 10% of his equity, if you think it's going to fail. Don't fix anything untill he signed, don't create a bug before you leave. It's a normal thinking pattern of narcissists and it ressembles "the expert beginners" POV. There are more opportunities, don't try to spend a lot of time on it anymore. Ps. This will probably go to court, if it's worth it.
