CloudFactory.com offers a web-interface and platform API to crowdsource your digital work to our "virtual assembly lines". We break projects up into small tasks and use microworkers around the world to perform each task then gather everything back up into your project results. (heard of Amazon Mechanical Turk?)
You can design your own assembly line or use one of our pre-built ones such as (image tagging, content filtering/moderation, transcription, data entry, translation, survey, geocoding businesses, etc). Then you can run multiple production runs on these assembly lines in the cloud by providing input data via spreadsheet, RSS feed or even a zip file. Or you can use the CloudFactory API to send work to your assembly line from a web application, desktop application or even integrate with your enterprise workflow.
Each virtual assembly line has one or more stations and at each station you designate either a human worker or a robot worker to perform the task. Think cloud labor meets cloud computing.
We also work with field partners in developing countries to train up and equip microworkers to do this sort of basic computer work. It is our goal and main motivation to provide work for people in the least developed countries wherever possible. We love what Kiva has done with microloans and would love to have a similar impact using microwork.
