You are really misusing the phrase "co-founder" here. You do not have 5 co-founders. Only one of the 5 is really clearly a founder (the one with 50+%). The other two are somewhere between "co-founders" and "founding employees". Especially since you acknowledge that there is an inequitable division of power/decision-making. In a situation with co-founders in the purest sense, all co-founders would have equal power. And then you have two investors, who are not co-founders. The two "co-founders" with less than 50% are "co-founders" in the same sense that Dustin Moskovitz, Andrew McCollum, Chris Hughes, and Eduardo Saverin were "co-founders" of Facebook. They were co-founders officially, but they were obviously 2nd to Zuckerberg and had far less power than he did (and none of them are at Facebook anymore) and were probably more like founding employees. At most you could say you have 3 co-founders. But really the closer truth is that you have one founder.
