Entrepreneurs outside of the major venture centers generally have fewer financing options than their venture center counterparts. Investors are scarce, farther apart, and have shallower pockets. Understandably, this makes many of these entrepreneurs very careful about controlling their burn rate. Which is good. Well, mostly.
Being frugal has obvious advantages for entrepreneurs with limited access to deep-pocketed venture capital resources. Most startups that fail do so when they run out of money (though - a topic for other places - in my experience the proximate cause of running out of money is usually management-related). Ergo, spending less prolongs survival which, all other things being equal, increases the chances for success.
