Watch the rich responses roll in!
Participants should keep 100% of their rewards. So we charge our platform fee on top (we reduce this fee for non-profit and academic institutions).
Our 250+ pre-set filters are free to use. Choose a representative sample for an additional cost.
Everyone’s time is valuable, so the minimum reward allowed is £6.00/$8.00 per hour.

Ethical data that benefits everyone
We invest in and protect our participants. So you can build your research on rich data and ethical practices.
Fair pay is crucial to high quality responses. Our minimum pay threshold ensures you get the detailed data you need and participants get the compensation they deserve.
We protect the identities of our participants. You get their honest responses because they feel secure in giving them.
Participants always opt in to tasks. They don’t have to take part in anything they don’t want to do.
