I just joined one of how workshops and thought it was pretty good!
There's a shortage of these kind of workshops here in Berlin and Europe (and probably also globally), and Camille is an engaging and witty facilitator. I could see this becoming pretty big.
Another attendee who runs workshops for lobbyists for a living estimated that people would pay 500€ for a (further refined) 4h workshop version of this (or 4x1h).
