Harj is not really interested in creating a service that "measures" a person's ability or "predicting" their future performance, because that's impossible to do. What they're really doing is creating a cargo cult tool that gives the illusion of being "objective" and using "data", so that they can sell the serivce based on this appearance, and later get bought out by LinkedIn or something. Perhaps they're doing a startup themselves because they had problems finding jobs due to hiring practices such as these.
