I think this is really misguided.

While it's true that the stack just enables you build something for people, if you just chase market you have a good chance of piling up technical debt and slowing down before you get there.

I have seen far too many projects take twice or five times as much budget as needed because people didn't know what they were doing from the get go.

Greenfield applications should start with a rough idea of what the technical requirements will be (what ordr of magnitude of users / transactions per second) and start by cloning a reference implementation that does what's needed. Otherwise you will never get ahead of product.
