The term is used loosely. Plenty of products described as mentorship platforms are really matching marketplaces — they introduce a mentor to a mentee and stop there, leaving scheduling, notes and payment to whatever tools the two already use. Others are scheduling tools with a mentoring label on them.
The distinction that matters is whether the software holds a record. A marketplace optimises for the introduction; a platform optimises for what happens over the following eighteen months. If it cannot tell you what was decided in the fourth session, it is not running the relationship — it is booking it.
A mentor evaluating one should ask three questions: does an engagement produce a durable record, does money move through the system, and can the data be exported on the way out. Those three answers separate infrastructure from a directory listing.
Mentor10
Mentor10 is built as the second kind. Its ten systems — from intake through to follow-up after the engagement ends — write to the same mentee record, and that record exports in full, in an open format, whenever a mentor asks.
