I’ve wondered this myself. Seemingly business associates before Villa, but I get the impression Sawiris is mostly the money behind it all and Edens is the sports business guy who’s created successful clubs before - not that he’s short of a penny or two himself.
Thing I like about Sawiris is when you see videos of him on YouTube talking about his businesses, he knows absolutely everything about the details. His knowledge about Nitrogen fertiliser is mad for example. If Villa don’t get it right under him, I don’t think we ever will with anyone.
