Freelance talent marketplaces like Catalant, Contently, Fiverr, Topcoder, Toptal, and Upwork are simplifying the mechanics of using freelancers. They provide spot markets to match freelancers to tasks and help hiring managers and HR find and manage freelancers. They handle administration, mitigate some risks, and are evolving rapidly to provide more traditional staffing and professional services to firms. Tech executives, supported by HR, should investigate these aggregators to plug gaps in project teams, particularly for on-demand digital skills.
