Has anyone leveraged a Segment integration?

Our VP of Product is looking into purchasing Segment (link), and she is looking to see if it could provide value to the Customer Success team.

I'm a little murky on the extra value it provides within ClientSuccess. We are an education-technology software company (B2B), and while we have a larger user base, most of them are "learners" rather than "instructors" who are the people typically added as contacts in ClientSuccess and own renewal decisions.
