I worked on the Danish government electronic invoicing project, and lots of people at the time I hung out with, being government people, knew what it was.

About a decade later I worked on the JavaScript implementation of NemID, NemID being a security thing in Denmark that basically every citizen has to use.

A coworker said to me (paraphrasing): "It's great to work on NemID, because everyone knows what it is, so it's easy to explain at family dinners" which is true. very true, everyone knows in Denmark what it is.

To which I thoughtlessly replied "Oh yes, it was the same when I worked on eFaktura", his face got the momentarily shocked and dismayed expression people get when they realize they are talking to a crazy person or an idiot.

About 5 minutes later I thought to myself "what the hell are you thinking, nobody knows what eFaktura is, fool"

I think the household name status of Slack or the guy who co-founded it is sort of like the household name status of eFaktura in Denmark.
