As of 2014, 53 million Americans, or 34% of the US workforce, made a living as independent contractors, according to data from the Freelancers Union. Moreover, a study carried out in 2010 by Intuit projected that more than 40% of the US workforce would be contractors and freelancers by 2020. Most of these professionals are involved in consulting work represented by almost 70 categories and implying some “knowledge transfer.”Unfortunately, the nature of such professional activities often leaves some blocks of work time unbilled. Consultants have no efficient way of finding customers that fit those unbilled time slots. This results in loss of income, which is especially painful for freelancers since they have no fixed salaries and always seek to maximize the monetization potential of their time.
