I've heard, "Product," be replaced with, "Prototype," where a prototype is not a pre-product but more a thing that can be offered that will give information about what needs you should be addressing, how the product might solve them, and help you identify who your most satisfied customers will be (among other things).

While you still have the agility you can only get from zero operational overhead, worry more about finding something people want, who wants it, and why they want it. Scaling is less than worthless if what you're scaling is worthless.
