We recruit committed B2B professionals for multi-session diary studies, tracking behaviour and decision-making over time with verified, consistent participants throughout.
A longitudinal study is only as good as its retention. Lose a third of the sample by week six and the trend you set out to measure disappears with them. Recruiting for these programmes is therefore less about filling a quota on day one and more about confirming people who will still be contributing on the final entry. IRG screens for commitment as rigorously as for professional criteria, and stays in contact with participants throughout, so the sample you finish with reflects the one you started with.
We screen for commitment alongside seniority and sector, then support participants across the full study period.
Participants confirm the full duration, entry cadence, and time per session before they are accepted onto a study.
Seniority, industry, and decision-making authority are checked by an IRG team member — the same standard as every other IRG brief.
We stay in contact across the study period, sending reminders and resolving issues before they become drop-outs.
Where attrition does occur, replacements are matched to the original screening criteria so the sample composition holds.
Multi-session incentives are agreed up front and paid on completion, in 90+ markets via PayPal or bank transfer.
Participants are sourced specifically for your study, not pulled from a list — which is why they stay engaged.
The same verified professionals contribute from first entry to last, so behaviour can be tracked over time with confidence.
106,900+ verified B2B experts across 90+ markets and 10 industries, at every seniority level from manager to C-suite.
IRG is a verified ESOMAR member and fully GDPR compliant. Participant data is protected for the full study duration.
