Then, how could a business identify its (or market's) trend-setters, enthusiasts, or whatever we call them, which will push towards something new? I see this as essential for either making the business better, shinier, or to avoid losing users.
By participating in the community. Content moderation on HN is so much better than on Facebook because dang is one of us, whereas on Facebook, it's a team of people in a developing country, in a different cultural context. Netflix needs to be run by film enthusiasts, not UX engineers trying to disguise the fact that all the good IP has been pulled back to the streaming platforms of the original producers. Spotify needs to be run by music enthusiasts, not people pushing covers of pop songs to avoid paying royalties to the original artists. And so on.
Indie Hackers is full of people trying to flog their shit AI-powered marketing SaaS, because they've never done anything other than software engineering, so they don't know any good problems to solve. There are uncountably many good problems out there, each with thousands of people who would pay you money to solve them, but those people don't know their problems can be solved by a computer, so you have to go out into the world to find them yourself.
Just like football scouts need to actually visit some niche teams and watch not that interesting stuff to find talent before it is too late.
With tech it might be easier because you might create niche groups so those people come to you.
Just like PG created HN. Nowadays HN is too mainstream so all ideas here are seem already popular so it is like going to scout high school t am that won local championship everyone already knows which players are lined for pro contracts.
By risk taking on good ideas rather than always trying to pivot your way from the status quo.
Product-Market fit is great if you're developing a SaaS business but it's not necessarily going to give you new inventions — something new is speaking to a potential gap in the market that doesn't currently exist.
Teams should identify their drivers of key metrics and do power user analysis based on this. A halfway decent analytics team should be thinking this way.
Ultimately, analytics are just a view into the business. This thread is complaining about doctors not using microscopes when diagnosing system issues - sometimes a narrow slice is important, sometimes you need to zoom out. If you focus on your "early adopters" or power users exclusively, without understanding how they affect the business, then you are at risk of building things that most of your user base doesn't want.
