Creating the President role fitting the legal requirement sounds like a great idea. Well done ! We will certainly go this way now.
My initial issue came from I've always heard that the CEO (if CEO there is...) can "stop playing the game" at any time, which I wanted to avoid. It would be a shame to start a beautiful and successful business and see one person going fancy one day and wanting to remove the rules, legally !
But I believe it may not happen, due to Holacracy actually, which allows every one to feel soooooo good working for the company that it may never occur !
Thanks to all for your answers that have definitely helped to go around my personal projection...???
All the best,
