Populiva vs Amazon Mechanical Turk
Amazon Mechanical Turk is a general marketplace for small tasks that many researchers once used for surveys. Populiva is built for research: verified participants, a pay floor, and quality evidence on every response.

- Deep integration with the rest of AWS.
Moving from Amazon Mechanical Turk
If you used MTurk's external-question HITs or a survey link, you already have most of what you need: a survey link and a completion code. Studies here pay at least $10 an hour, so check your budget against our pricing.
