Well Pieter Levels has a negative customer acquisition cost because he gets most of his business off of X and he gets so many impressions that he gets paid to post there. That's a pretty incredible marketing hack if you ask me. I invest in startups and the ones who do really well hack marketing. They have tech in their stack that is specifically devoted to automating and scaling their marketing.
But if you listen to Levels' interviews, especially before his Twitter stardom, you will see that he always promotes the find your audience and build to them approach.
your audience is supposed to guide what you're selling. The fundamental belief is getting the audience is harder than building something they want. This part is probably true, while the rest of the ecosystem is garbage and scams
