It would be interesting to see: 1. How the online ones are doing financially. 2. Which sectors are doing well - what are the trending tools. Skimmed through PH APIs, don't think this is possible. Courtland's Indie Hackers (they have stripe verified revenue) maybe of help - a quick google resulted in this¹ result There's also microconf report on SaaS's² [1] https://www.indiehackers.com/post/indie-hackers-are-making-6.…
Revenue would be near impossible to do, however we could have analyzed traffic using SimilarWeb or Ahrefs API. We could also have analyzed the sitemap to check the last update date. Those articles are really fun to write (I haven't written this one, I'm just the editor), but at some point you have to stop otherwise you end with a 20k words essay.
I think the parent article is interesting, thanks for your contributions. I am not saying that the same should have contained revenue, performance data - just that it would be interesting to see :)
