Regarding your 2nd paragraph: Yes, the true problem is not marketing itself with all its practices. The real problem is to make the user get into a habit and do it consistently. To help the user make it happen, I intend to add some kind of gamification and rewards. I was thinking about making it similar to those fitness apps that help the user eat less and exercise more.
In this case, the message would be "build less, market more".
Is your market people who don't want to build but want to market? I thought it was the opposite. Maybe something like, "spend your time doing what you like and still get users"
Similar to someone who wants to lose weight without exercising.
Yes, maybe saying "exercise more" is dumb because it would scare people away or make them say "Duh! Could have told you that!".
Maybe when I push it more into the direction of an "AI marketing assistant", the message could be like you said.
I must think about this, thank you so much!
Since it's marketing for devs who hate marketing (I'm one of those) I think if you get too deep into marketing best practice it would be tedious/boring. Just give small actionable things you can do given the data you input about the product. That would be useful. Problem for me is I know what I should be doing, but I'd rather just code the product. So it's a hard problem to solve.
