Ask HN: User Centric Product Metrics?

I'd like to create an automated report that tells me where a new user is in their journey of discovering my product. In particular, I want to easily be able to see which of the core actions a user hasn't taken yet so that I can send them a tip.

So far I've been using Segment, Google Analytics, and Amplitude but I haven't yet found a way to quickly answer this question.

Does anyone have a similar workflow? What kind of tools have you used? Did you build something custom?
