Freelance talent marketplaces like Catalant, Contently, Fiverr, Topcoder, Toptal, Upwork, and Vicoland simplify 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 also handle administration and invoicing, mitigate some risks, and are evolving rapidly to provide more traditional staffing and professional services. Hiring leaders, supported by HR, should investigate these aggregators to plug gaps in project teams, particularly for on-demand digital skills.
