“Quality research starts with a good sample. To recruit qualitative and representative participants, we have relied for years on the teams at Defiline. With them, there's no guesswork, only quality."
Kim B.
CEOI'm delighted with B-field's work. They carry out all french recruitment for JPCR's qualitative studies with great professionalism, and I'm always very satisfied with the quality of the participants selected for our studies, who fit the criteria perfectly. All participants are reconfirmed or replaced on time if necessary, saving me the unpleasant stress of last-minute cancellations.

Recruitement in various languages
B-Field excels in recruiting participants from diverse linguistic backgrounds, enabling you to access and understand insights from a broader range of demographics, crucial for comprehensive market research.
Translation and transcription of sessions
To complement our recruitment services, we offer detailed transcription and translation of focus group sessions and interviews, ensuring you have access to accurate and understandable data in your preferred language.
Panel size
Our database includes over 25,000 individuals, allowing us to provide a wide range of respondents. We can cover Brussels and all major cities in Wallonia, ensuring a diverse and representative sample for your needs.
Screening and qualifying respondents
We ensure that all respondents meet the required profile through a two-step process. First, they complete a screening form to gather initial information. Then, we follow up with a phone call, where we ask the same questions in an open-ended format to verify the responses and confirm the respondent’s suitability. This process helps us ensure the highest quality and accuracy in our respondent selection.
Measurement and reporting
We do not offer measurement and reporting services. Our focus is on providing high-quality respondents, and we recommend working with specialized providers for any measurement or reporting needs.
Incentive and compensation
We can manage incentives and compensation for respondents if needed. Please note that an additional fee will be applied for this service to cover the administrative costs.
Budget and timeline
The budget for your project will vary depending on several factors, such as the target audience, whether the study is online or offline, and the level of commitment required from the respondents. To ensure smooth planning, we kindly ask for the final screener at least 7 business days before the scheduled panel discussion. If the timeline is shorter, additional costs may apply.
