Is it the responsibility of any project/startup to find out who the LPs are for a VC fund? Sometimes this information is not only inaccessible, it would be illegal for you to know. Especially in a case where - wait for it - a sovereign wealth fund might be involved. So... call me crazy, but I don’t think Leonardo DiCaprio did anything wrong here. I’m sure he’s used to rich aholes giving him money and trying to buddy up with him all the time, why would one seem more suspicious than the others?
