CrowdFlower

Some of our customers:

Managing our Mechanical Turks tasks via CrowdFlower was incredibly convenient, and made crowdsourcing our data simple and intuitive. The step-by-step guide to design questions was remarkably clear, and being able to set targets for the number and speed of responses was really helpful.

CrowdFlower provided quick turnaround and accurate results on a categorization project—a joy to work with.
—O'Reilly

CrowdFlower provided us a lot of high quality data, much faster and at a fraction of the price of other methods we considered.
—Scout Labs

We will use them again and highly recommend their services.
—Zvents

CrowdFlower's service, UI, and excellent turn around time are allowing us to quickly scale our operation. The task and system we developed was unique for your video image processing product. They were very responsive during development and we cycled though multiple iterations a week.
