Here's what I've found, Disciplina.io by Teachmeplease team.
I'm not yet sure, for I'm new in cryptoworld, but it seems promising. You know, education, tutors around the world. Their WP is sensible, and the team is fine. They're russians, though - unpredictable?
I read somthing similar but it had another name like live edu..or something. I can say that the idea to make education better by changing the whole system is really nice and deserves feedback
