At best it's pick two. Often you get one or none.

I need to remember that on HN, sometimes the founders of companies I'm talking about will respond :D. I should've used more words.

I don't really know what reasonably costed would've looked like for the time I used Amplitude (2018-2019), but I know that the value my team extracted from it was not commensurate with its cost. Whether that was because of overzealous assumptions on our part, or something else, I don't really know, but I know we signed up, used for a few months and then canceled/downgraded to a cheaper service whose name is escaping me.

I was mostly challenging the "Just use ____" notion of the commenter above, not really that Amplitude is worth the money for correctly-intentioned businesses. Regardless I appreciate the ask.
