While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

In-person study interview
I attended an in-person study interview last year and the whole process ran very smoothly, from the preliminary contact to the interview itself. I wasn’t sure what to expect but the person leading the interview made me feel at ease and the hour flew by. I got paid promptly and would definitely consider doing it again.

My first study
I participated in a study back in December and was impressed by how well organised the entire process was. It was highly informative yet efficient. From start to finish, it was a smooth and professional experience. Would happily do it again.
