Respondent matches people to paid research studies — interviews, unmoderated tasks, diaries and similar — after you create a profile. There is no full public list of live studies that we can republish, so this site does not invent individual openings.
Official participant referral terms, when we read them, paid $20 when a new user had earned $75 or more from completed studies, and $50 when they completed a referred project with a $100 or higher incentive, with a cap of five project-referral bonuses per project. Payments were described as Tremendous gift cards. Existing accounts cannot usually be tagged later.
If you already want to join, the button below will use a referral signup link once it has been added in the site config. Until then it opens Respondent’s official studies page.
Ad If you sign up through this link and later complete qualifying studies, Respondent may pay this site a referral reward. That does not change your study incentives. Signing up directly is fine.
