They coordinate Reference winners, Ambassadors and Mentors. If they are coordinate only inside the country – we call them National Coordinators and if they are coordinate among more countries – we call them International Coordinators.
We need Coordinators in small companies or in case if the Ambassador of Knowledge is a person working in no company (like freelancer, actor, artist, etc.).
*Ambassadors of Knowledge can’t be the mentors because of conflict of interest. In this case Coordinator helps.
