Where did it all start?

Our story

Our story starts in 2012, when we were conducting our own academic research. We would often need the general public to take part in surveys, interviews and experiments. To get participants for our research we would send out a ‘call for participants’ through our social media channels and the university mailing lists. However this would only reach our friends, family and colleagues, who were not always suitable for the research, or there were not enough of them. But in order to let the general public know about these opportunities to take part we needed a new way to communicate.

Contrary to popular belief, the research activities taking place in universities across the world every day are far from boring or “academic”. If you take part, you can find your self testing car simulators, playing with lego, trying different types of cakes, or even counting craters on Mars. And often you are rewarded for doing so with financial compensation, vouchers or other various rewards spanning from a sincere “thank you!” to theme park tickets. Therefore, to help us reach the general public and showcase all the great opportunities available, we built callforparticipants.com.

Since launching our service we have seen significant growth each year. To ensure we continue to provide value and keep up-to-date with our customers needs, we have been working collaboratively with universities, charities, and the education sector leaders such as Jisc:

“Jisc offers digital services and solutions for UK education and research. The charity does this to achieve its vision for the UK to be the most digitally advanced education and research nation in the world. Working with Call for Participants helps Jisc achieve this vision as it helps researchers with the thorny problem of finding the right people to take part in their research. Making this easier for researchers saves universities time and money. So far Jisc has supported Call for Participants with £80,000 and our calculations indicate that the service has already delivered well in excess of that value to the higher education sector. We believe that together Jisc and Call for Participants can offer this exciting new service to universities and researchers across the UK and so we are planning to work with Call for Participants to trial a new approach to supporting start-ups to ensure Jisc customers benefit from their innovation.”
