I have been approached a couple of times by friends with 'ideas', they just need a programmer to build it for them. I respectfully declined each time and remain friends with these people.

None of them ever got anywhere with their ideas. They never quit their day jobs, they never read the right blogs and books (even if I suggested, and in some cases bought copies of the books for them), they never raised funding, they never talked to customers, and they never found another programmer. They had absolutely no idea where to even begin on the business side of things, much less the engineering side.

I think programmers get all hot and bothered by the idea of a 'non-technical' co-founder undervaluing their contribution and so we all love these posts. But really, most of the people saying they are 'looking for a technical co-founder' aren't just lacking the ability to code. They are lacking the ability to do a startup.

Calling them 'non-technical co-founders' really is giving them a free pass. Most aren't ready to be co-founders, technical or not.

It also really belittles a good business cofounder (lets not term it around what they can't do, but what they can do). A good business cofounder goes out and talks to customers, has a handle on the market, probably has a contact list full of potential partners or employees, can pitch, do some PR, and hopefully secure some funding. That is very valuable to a young startup, and most of the people with an idea and no coder aren't up to that level.
