A service segment of the Talent Acquisition Technology Industry. The Human Cloud is an emerging set of work intermediation models that enable work arrangements of various kinds to be established and completed (including payment of workers) entirely through a digital/online platform. In many cases (though not always), the platform also supports “the enactment and management” of the work (to a lesser or greater degree). Job boards and social networks do not fall within our definition of the Human Cloud; while those two types of talent exchange platforms may support the sourcing and recruiting part of work arrangements being established, such platforms do not further enable or support work arrangements through to their completion (including payment of workers, tax filings, etc.). Staffing Industry Analysts has defined three types of Human Cloud platform models: Crowdsourcing, Online Work Services and Online Staffing Platforms (See definitions). Some companies operate across more than one of these Human Cloud segments.
