الشركات التي تستخدم CrowdFlower في الولايات المتحدة

CrowdFlower is the world's leading crowdsourcing service, with over 800 million tasks submitted by over four million contributors. We specialize in microtasking: distributing small, discrete tasks to many online contributors, assembly-line fashion - for instance, using people to check hundreds of thousands of photos every day for obscene content.
