How to recruit participants for qualitative research: method, timing and cost

Updated 30 September 2026 · Rarelyst

The short answer

To recruit participants for qualitative research, describe a specific person rather than a demographic target, verify their identity and experience before the interview, and pay them in line with their expertise. With Rarelyst, a fashion, luxury or beauty brand gets its first verified profiles within 72 hours and only pays for the profiles it keeps, at the price agreed after a demo, participant incentive included.

1. Describe a person, not a target

Most failed recruitments start with a brief that is too broad: “women, 25–35, upper-middle class, Paris region”. Thousands of people fit, and none of them will tell you what you need to know.

Describe instead the person whose opinion would move your decision forward: “a luxury boutique associate who advises Asian clients every week”, “a collector who buys on drop day and resells on Vinted”, “a stylist who dresses artists on tour”.

2. Verify before the interview, not during it

On Rarelyst, every proof becomes a medal on the profile: identity checked by the team, LinkedIn account linked, employment confirmed by a code sent to a work email, CV analysed, portfolio reviewed, and ratings from brands that have already interviewed them. The team reviews each profile before suggesting it.

3. Run interviews without the back-and-forth

Participants suggest time slots, the brand picks one, and the video room, reminders and recording happen on their own. You run the interview with your guide on screen. A self-guided option (beta) lets participants answer the guide's questions on camera, at a lower cost.

4. Demand a synthesis that answers your decisions

The synthesis answers each decision written in the brief, with how many people lean each way, an honest confidence level and participants' exact words. Every quote is checked against the transcript.
