The Company

Prolific (www.prolific.ac) brings people together to power the world’s research. It is the first scientific, highly scalable, ethical participant recruitment platform for researchers around the world. Quantitative and qualitative researchers, data scientists, and entrepreneurs all need valid and reliable data sources to make predictions about human behaviour, social change, and global developments. Thanks to our online platform, researchers collect responses fast and participants earn cash rewards for themselves or for charity.
