I hope you got some valuable experience here. Some bad, some good. Some development, some software, etc. Be abused and say "No" - is GREAT experience too. You are set here. It's definitely no reason to work for such compensation.
1) Silently find a new place to work. (there is no reason to negotiate with your current employer, since he wont be able to raise compensation 4 times and give you all other stuff for sure)
2) Tell founder that you are leaving in 1-4 weeks.
3) Tell him why you are leaving.
4) Tell him that he have option to hire freelancers (you are freelancer now accordingly to way he pays you) on oDesk.com, elancer.com, etc sites. He will get really good quality on these sites and in the same time these $500/wk wont be abuse to these people.
I mean, if you are really good, and it looks like you are, you should fight for much better compensation/results for your - you have wife and kids now!!! And in the same time if your employer can't pay enough you - he should rebuild his business to outsource some work to other countries to not abuse local people.
