Question

Startups

Hello. I did not even know what tags to choose for the question. Immediately to the task:
There are users whose character we know (to one degree or another). Let it be a utopia in which we ideally define "what" you are as a person.
In addition, we are able to determine how one user "suits" to any other user - by character (by some individual traits), by interests, by inclinations, etc.
Question:
What useful / interesting / cool / cool / etc. project can be created based on the knowledge and skills from our utopia?
