Two-sided marketplaces are environments where you primarily have two distinct user types: buyers and sellers. There are many different marketplaces out there: GetNinjas in Brazil, Fiverr in the United States, and OneFlare in Australia are all marketplaces where people can find professional service providers like plumbers, photographers, personal trainers, or more; jobs boards, like Indeed or ZipRecruiter, are marketplaces where job seekers can connect with prospective employers or recruiters; 99Designs and DesignCrowd are marketplaces connecting people with graphic designers; Upwork, freelancer.com, and Peopleperhour.com are marketplaces for freelancers. The list goes on.
