Has your co-founder brought in any sales? 

No, but we plan on going to sales meet together.

    Does he have any industry expertise? 

No, I had to explain the industry in it's entirety.

    A strong network of customers/advisors/investors? 

No but knows other sales people.

    Is he leaving a high paying job? 

I think it's high paying, but not 100% sure what he's salary is.

The thing is he does feel like a co-founder, he got everything I explained very quickly, we think similarly and dig the vibe. Now he wants to code and help out on the dev side (as he's done it on the side on and off), which I welcome.

Do you mean after a year, both of us start earning equities? What does it mean to vests? I will consider a lawyer.
