Trusted for 10 years by leading academics, researchers and organizations

I'd recommend Prolific to anyone looking to quickly gather high-quality data, especially if they need to recruit specific kinds of participant. I honestly don't think my research would have been possible without Prolific.

Researcher, Google

Prolific’s demographic and distribution filters help us meet our participant diversity goals. Prolific makes it cost-effective to find and vet appropriate study participants.

Researcher, Modality AI

Prolific greatly facilitated the recruitment of high-quality research participants, including participants from more unique and difficult-to-recruit populations. The efficiency with which we were to screen and recruit participants greatly reduced recruitment time and allowed us to substantially increase our sample size.

Matthew Tull, Professor, University of Toledo

AI research is typically data hungry, and our development of robust models has relied in part on the large data samples we have been able to collect for our tests. With the ability to pre-screen participants based on demographic characteristics, we have also been able to collect data from population segments that are often underrepresented, and ensure that our technology is developed in an equitable manner.

Novoic

AI is changing fast, so it’s really valuable to be able to rapidly collect responses. For small or large samples, I’ve typically collected data within 24 hours for all the studies I’ve run on Prolific.

Janet Pauketat, Research Fellow, Sentience Institute
