Scalability is unnecessary when you're not growing rapidly. But when you are growing rapidly, it's suddenly very important. And if you didn't think about it before, it's already too late.
You don't have to build to scale right now. But you should have a plan of when you're going to need to scale, and how you'll do it. Or don't, and wait until your pants are on fire and then run around screaming.
