I'm sorry you are having a tough time but you need to either 1) have a hard talk with your co-founders about your business model. present facts. make your case. they will listen.
or
2) if they dont, walk away and start something new. you mention you are a few years out of college. you could also go take all the technical experience you have gained over the last year and get another job. Make a decision on your own.
But really, the notion that a bunch of internet strangers will be able to give you some miracle advice is absurd.
