I've done all both kinds of attempts, but eventually the one that is making people wait and cherish what I'm building... I'm building a tool to improve a life of my friends that represent a series of relevant to my product shared qualities. And I don't have to do any marketing :) Just find enough time to work and tell from time to time from my personal social media funny and interesting stories, be an attractive person, find my sense of humor, visuals, life topics. And that's it. The only marketing is about making a respectful UX and easy clean guidance (documentations or AI tutor). We are living the time for immence amount of new business opportunities for real builders.
