Frequently asked questions about participant recruitment

Cost depends above all on the target group, the number of participants, the method, session length, the verification effort required and the timeline. A widely available B2C audience is usually less expensive to recruit than specialised B2B decision-makers, healthcare audiences or very rare profiles. Insight Fox therefore does not quote flat fixed prices without project context. Our project assessment gives you an initial, non-binding price orientation. A binding offer is only prepared after we have personally reviewed the target group and requirements.

The main cost drivers are how rare the target group is, the number of criteria, regional restrictions, the verification effort required, the number of participants, the speed of recruitment and the level of incentives. Method matters too: a straightforward remote IDI is costed differently from a demanding ethnographic project or a very short-notice B2B recruitment. What matters is not just finding someone who formally passes the screener, but making sure the person is genuinely suitable.

In many projects Insight Fox can recruit very quickly. What matters to us, however, is not maximum speed but the quality of the participants. Real people need to fit an interview or a research study into their everyday lives – and that sometimes takes a little lead time.

In B2B in particular, suitable professionals and executives cannot be “produced” at arbitrarily short notice. They have full calendars and internal commitments and need to plan time for participation. Extremely fast recruitment is therefore not automatically a sign of quality. On the contrary: if demanding target groups appear to be effortlessly available within a very short time, it is worth taking a closer look.

We work fast, but not at the expense of quality. For straightforward B2C audiences, recruitment can often be completed within a few days. For more complex B2B, healthcare or niche audiences we plan the necessary lead time realistically. If a requested schedule is not credibly achievable in our view, we say so openly before the project starts.

We look at every project individually. Very small projects can make economic sense if the target group is clearly defined and easy to reach. With demanding target groups, however, there is a certain base effort for project management, screening, validation and quality assurance regardless of the number of participants. Small projects may therefore involve a minimum effort. The specific assessment is always project-related.

The incentive should match the target group, the duration and the effort involved in taking part. A short B2C study calls for a different incentive than a one-hour B2B IDI with a hard-to-reach executive. Incentives that are too low make recruitment harder and can compromise sample quality. Incentives that are too high, in turn, can attract the wrong applicants. We therefore recommend realistic, market-appropriate incentives for the respective target group.

Yes, provided the target group and the requested timeframe are realistic. For short-notice projects we check particularly carefully whether speed and quality are compatible. We do not promise a date just to win an order. If a target group cannot credibly be recruited within the requested window, we say so openly.

We do not rely on online screeners alone. Qualified candidates are additionally checked in person. We verify relevant details, assess motivation and communication skills and watch for inconsistencies. For B2B audiences, professional details can also be verified via publicly accessible sources. Our aim is not the largest possible number of matches, but the right participants for the specific research objective.

Screener responses are reviewed manually. Among other things, we look for contradictory statements, implausible response patterns, conspicuous wording and criteria that do not fit together. Candidates are never accepted or excluded automatically on the basis of a single algorithm. Where anything is unclear, we follow up personally.

An online screener shows whether someone formally meets the criteria. It says little about whether the person understands the topic, genuinely belongs to the target group, is motivated or can express themselves meaningfully in a qualitative interview. Personal contact is therefore a central part of our quality assurance. For complex B2B or niche projects in particular, this step can be decisive.

We look at participation history, response behaviour, motivation and the plausibility of the information given. Conspicuous candidates are examined more closely. Frequent study participation is not automatically a reason for exclusion, but it can be relevant if it affects suitability for the specific project. The goal is an authentic sample, not a group of seasoned participants who have learned how to pass screeners.

We combine several checks. These include personal contact, plausibility checks, cross-referencing existing data, duplicate detection and, for B2B projects, verification of professional information via publicly accessible sources where appropriate. Suspicious or contradictory cases are never released automatically.

Contradictions are reviewed manually. Depending on how significant they are, we contact the person or decline participation. We also document which criterion was not met or which statement was implausible. This keeps the decision traceable and can also indicate whether the screener itself is ambiguously worded.

We aim to minimise drop-outs through active confirmation and reminders before the appointment. Participants are contacted again ahead of sessions. For critical projects, backups can additionally be scheduled. Even so, short-notice cancellations or no-shows can never be ruled out entirely. What matters is that such situations are recognised early and managed professionally.

We recruit B2C and B2B target groups for qualitative market research, UX research and related research formats. These include general consumers, specific user groups, professionals, decision-makers, executives and other specialised profiles. What matters is not the label of the target group, but whether it can realistically be reached and credibly verified.

Yes, B2B recruitment is one of our core competencies. At the same time, we say openly when a target group is barely reachable due to seniority, industry, company size, regulatory restrictions or very narrow criteria. We distinguish between difficult and unrealistic. Making that assessment is part of our job.

Yes, provided the specific target group and study design can be implemented credibly. Healthcare projects often require additional care in verification, data protection, incentives and communication. We therefore examine the requirements particularly closely before the project starts.

Yes. With decision-makers in particular, however, the key question is whether the requested role is actually involved in the relevant process. A job title alone is not enough. Wherever possible, we therefore check function, area of responsibility and involvement in the specific decision.

We decline projects when we cannot credibly recruit the target group under the given conditions, or when the quality requirements are incompatible with the budget or timeline. Unrealistic quotas or contradictory criteria can also be a reason. In our view, an honest no before the project starts is better than a project that fails later.

We consider the size of the target group, reachability, the combination of criteria, region, method, incentive, timeline and the verification required. Added to this is our experience with similar target groups. A good feasibility assessment does not consist of automatically saying “yes”, but of identifying potential bottlenecks early.

Then we communicate this early and, where appropriate, suggest alternatives. That might be an adjustment to individual criteria, a different regional scope, a revised schedule or a changed quota. If we believe that nobody can credibly deliver the target group under the given conditions, we say that openly too.

At the outset we clarify the target group, method, number of participants, duration, schedule and relevant criteria. We then assess feasibility and align the screener. Potential participants are identified, screened, reviewed manually and, if suitable, validated personally. During recruitment, clients receive regular updates. Before the sessions we reconfirm participants and support the project through to the end of fieldwork.

It helps to have a description of the target group, the number of participants, the method, remote or in person, the length of each session, the fieldwork period, the location and any existing screener. The more precisely the target group is described, the better we can assess effort and feasibility.

Yes. Clients can provide their own screeners. We do, however, review them from a recruitment perspective and point out criteria that are problematic, ambiguous or hard to verify. On request, we help optimise them.

Yes. For difficult target groups in particular, a good screener is decisive. We focus on clear wording, realistic exclusion logic and criteria that can actually be verified. Our emphasis is on recruitment quality, not methodological overload.

We report proactively on project progress. The exact frequency depends on the project. If difficulties or delays arise, we do not wait to be asked – we get in touch early with an assessment and possible ways forward.

Yes. A customer dashboard is available for commissioned projects. There, clients can see project status, progress, published quotas, relevant milestones and current project updates, among other things. The dashboard serves transparency, not the operational control of the project.

We work with institutes, agencies, UX teams, research departments and companies. What matters is not the type of organisation, but that the research project is planned credibly and the recruitment requirements can be clearly defined.

Data protection is a central part of our processes. Personal data is processed only for the respective purpose, and access is restricted according to roles and project requirements. Which data is processed and which rights data subjects have is explained in detail in our privacy policy. For sensitive projects we assess additional requirements on a project basis.

No personal participant data is displayed in the customer dashboard. Clients see project-related information such as progress, quotas, milestones and status updates. Which personal information is required as part of the actual research depends on the respective study design and the agreed processes.

In Germany we recruit in major cities as well as in smaller towns and rural regions. For international projects we work with long-standing local partners. Insight Fox deliberately positions itself as a specialist for the German market rather than an anonymous global panel platform. For international projects we coordinate recruitment with suitable partners on the ground.
