I like the "hostility" towards business guys in an early stage startup where delivering a product is key. If they can't build it, they have nothing to do there, not early on anyway. A single developer who can design > business guy. Keep it up! "2) sales and marketing are usually vital for growing businesses?" sounds more like hostility against developers, as in marketing is some obscure dark magic?
