Remember when people thought Superhuman was the next thing?
It still sorta..is?
I know of and have seen a lot of very important founders and CEOs who still all swear by Superhuman.
The same people who thought that sort of thing, probably over-invested.
Once they (investors) have realized that there is no growth or anything to extract, or a lack of further fundraising, then it is written off and they move on.
They need to work on growth.
