Is this product extensible beyond SaaS style tiered subscription models? I love the pricing space, but at first glance, the limitation in your company's scope seems depressingly limited and is essentially hard-coded into the name of your company (Tier). I have grandiose ideas, hopes and dreams of what the pricing space will look like in the future, and it doesn't involve immutable JSON files. But I can see why this would be really useful right now. Looks great.
