Is there a step in here where one develops a minimum lovable product, or builds a solution for users’ “job to be done”?

Without that step, it reads something like a “... profit!” meme.

That's the part you outsource, until you can find someone naive enough to bring on board full time.

I thought it was satire.

Or instead of using $5k credits in AWS you could just get a $5/mo VPS which is probably powerful enough for testing most startup ideas.

This feels like a 'fake it till you make it' to the extreme. Where is the actual product/functionality? A landing page without anything behind is just empty promises, isn't it?
