How it Works

Our workers are presented with one item at a time and asked to verify one attribute or all information shown. We present workers with a recommended list of sources as well as a list of invalid data sources. Workers then search online or make phone calls to verify the information requested. If a worker determines that the information is incorrect, the worker will provide the corrected information and the source it came from, letting you update your database with accurate data. You can send us the data you need cleansed in batch files or in real time through our application programming interface.

Advantages Over Traditional Methods


By combining intelligent software with human cognition, you get benefits of subjective analysis and algorithmic quality control. By verifying results with redundant tasks and Gold Standard Tasks (aka "known answers"), quality is monitored and measured in real time.


With a workforce of more than 500,000 workers capable of completing data tasks, jobs that used to take months are completed in hours.


We offer a fully elastic model, letting you scale up and down on demand.
