The difference in money, and perhaps more importantly, time, between great software and good-enough software is large enough that most companies will require good-enough.

There are two big trade-offs in time alone: missing the chance to be first to market (mongo vs rethink comes to mind, albeit not quite accurate), and the need to get feedback early and often enough to pivot if the idea isn't quite right.

Then the layers of lava come- not enough time to rewrite everything now that the domain is better understood, the prototype becomes the foundation, and cruft builds up.
