Edit: ...do you?
Maybe the idea will interest someone, maybe someone here was thinking about the same thing but never got it started. It is what it is. What do you find "wrong" with his posting, maybe it will help clarify your criticism?
"This looks like every other business guy looking for a tech founder" is the important part. The fact that "significant equity stake is on the table for anyone who fits the bill" is missing from an otherwise pretty well thought out post makes me think that in fact, comparatively to 50%, they are going to "offer almost nothing".
But look, If I'd prototyped and market tested something, I'm not so sure I'd be prepared to give away 50% either. Just sayin.
If I'm going to toil away on a project for NO PAY (which is a huge risk), it better damn well be for a huge chunk of the profits.
I have been around many business types and have seen developers put their hard work into something with little or no payoff.
My hunch is that he offers 5% or less, which is a joke.
Because he already stated that the co-founder gets no salary. He never mentioned the actual percentage, so it's a fair assumption.
Not mentioning exact equity, how do you assume 5%!?!?
It is very common for cofounders at an early-stage startup to take no salary.
I hope you are offering 50% equity. If not, it's not worth my time. This looks like every other business guy looking for a tech founder: you want to offer almost nothing for doing all of the hard work.
