YC sounds alot like the c-founder type you describe. it doesn't look that way with all the hype but think about it... ( like a good engineer) would google founders have fallen for YC's offer?
Yeah, except YC takes ~5% while the annoying business c-founder type take ~80%. And I'd argue YC even provides considerably more value than most 'business' co-founders.
by the way if I had even 1% of google I'd be so rich :)
