Ah, billionaires. The size of their bank accounts is matched only by the size of their egos.
So when they do spend their money, they want to do it with panache.
That's why most impact investing funds and high net worth individuals don't want to simply put their money into a large equity stake in a traditional company or to back existing causes that make incremental differences every day. Booo-ring. The investment has to make headlines and, most importantly, particularly when it comes to tech giants, it needs to be more futuristic than the other magnates' pet projects.
