In my opinion, for a two person team, both have to be technical founders and at least one of them has to have some product sense to build anything useful. For a three person team, however, you can afford a dedicated business person. There is certainly value in having somebody around who is _willing_ and is _looking forward to_ taking on all of these things. Having said that, to me a business guy is defined by his experience. Loosely defined, I can call myself a business guy just because I'm willing to take on responsibilities that are not coding. And I believe I will be as good (and bad) as any other inexperienced business guy. Our respective backgrounds and education will mean absolutely squat when it comes down to getting the business off the ground. This is why a business guy with no experience is just an empty term to me. Until he has started and ran a business he is no more of a "business guy" than I -- we're both just "aspiring businessmen" and only one of us can code.
