The company says those judgments are “the crux of microtasking”, with businesses asking CrowdFlower contributors to do things like judge whether an image is appropriate or whether an address record in a marketing database is complete. The billionth judgment was made by someone in Cariacica, Brazil, who was verifying database details about an Australian small business for a US company.
CrowdFlower was co-founded by Chris Van Pelt and Lukas Biewald (Biewald is the company’s CEO, as well as a former college roommate of mine.), launching at the TechCrunch50 conference in 2009.
The company also says it now has more than 5 million contributors. Recently announced features include the ability to test users for certain skills, so that CrowdFlower can identify “higher value crowds” among its contributors.
