Their startup: http://collectivedecisionengines.com/ seems to give decision makers X units of currency and then refund them the average outlay.
It seems like it would have failure modes in communities w/ transient populations. As in, if you give me 100 units, I'll buy 10 votes and know that I at least voted as much as I could. But in conditions where you have a fixed community it could work well.
Clearly in the real world if you have 100 credits, a Koch brother would have ~100 million credits... Bill Gates ~200 million credits... (based on US median net worth of $44,000 vs their respective 42billion and ~80billion)
But there are plenty of decisions to be made that could be done with fake credits in a controlled environment.
