You probably don't want to hear this, so please excuse it if that's the case:

I taught myself software engineering so I could be my own technical founder. To be honest, I think I'd want a 2nd technical founder before a non-technical founder.

Unless the non-technical founder had some solid business knowledge/skills/experience. Barring that, depending on the product/market domain, I would still seek: technology skills/experience, such as software, electronics, science, or engineering related.

And I studied liberal arts in college ;)
