There's some irony and conflicts of interest. People make slick landing pages and try to get interest to decide if enough people sign up for a thing that doesn't exist yet, then "it may be worth building it" But also potential customers are fed up of such tactics and want to actually try a product before signing up to another thing which may or may not ever exist. So what happens in the end sometimes is that the developers may think "nobody signed up for it so I will pivot". Would love to hear opinions and experiences about it though for success and failure.
