Exactly, two opposing frameworks that produce varying degrees of great results.

I've always been more into the Steve Jobs/Henry Ford model of "customers don't know what they want until you show them".

At the moment we're a team of two, myself (software engineer & product), then my co-founder (operations). We're looking to find a third (software engineer), so if you know of anyone, do let us know! We'll be building a team next and going for funding.
