For the majority of our studies, we accept people between the ages of 18 and over who are in the SF Bay Area.
We appreciate everyone who signs up to join our testing program. Participation in research studies depends on a wide variety of factors, including but not limited to demographic information, shopping behavior, and product usage. Therefore, not all who sign up will be able to participate in many studies. Just receiving an email or a call regarding a study does not guarantee participation in the study.
