How do you recruit useful customer-interview participants?
Recruit people whose recent experience matches the question you need to answer. Define that experience, choose a suitable recruitment channel, screen briefly and explain the session before booking it. Make participation voluntary, obtain informed consent and collect only necessary information. Plan accessible participation and disclose any incentive. A full calendar is not evidence of market demand; the point is to hear from relevant people, including those who may contradict your assumptions.
This guide covers routine customer discovery with adults. It adapts UK government research guidance into a practical startup workflow; it is not a legal compliance template. Have privacy and consent arrangements reviewed for your jurisdiction, and obtain specialist safeguarding advice before research involving children or vulnerable participants.
What experience should qualify someone?
Start with the decision, then describe the experience needed to discuss it. “People who love productivity tools” selects enthusiasm. “People who personally scheduled customer appointments recently” selects a task.
The GOV.UK recruitment-brief guide recommends recording participant criteria, session dates and length, location, numbers and incentives. It also says to review an agency's screening script against your actual requirements. Use a written brief even when a colleague handles recruitment.
For a fictional appointment-reminder study, our proposed criterion is an adult who personally arranged appointments during the past month. The month is an illustrative choice for this example, not a research standard. Include people whose existing arrangements work well; requiring dissatisfaction would preselect the conclusion.
What should a short screener ask?
A screener checks whether someone fits the research question before scheduling the interview. It should not become the interview itself. These original example questions are for the fictional appointment study, not a validated questionnaire:
| Question | What the answer helps establish |
|---|---|
| During the past month, which appointment-related tasks have you personally handled? | Relevant recent activity; allow “none” |
| Which parts did you handle yourself, and which did someone else handle? | The participant's role |
| What did you use to arrange them? | Existing process, including paper or another person |
| Would you be willing to discuss that process without sharing customer details? | Whether the proposed conversation is suitable |
| What contact method and session arrangements work for you? | Practical participation needs |
Do not ask applicants to upload calendars, client lists or account screenshots to prove eligibility. Record an unclear answer as needing clarification rather than silently treating it as a match. Keep scheduling details out of the interview evidence table.
Where should you look for participants?
The GOV.UK participant-finding guide describes recruitment agencies, relevant organisations and existing users as possible routes. It calls for permission before inviting existing users into specific research activities.
For this example, start with an appropriate business network willing to circulate an invitation, or customers who have agreed to hear about research. A specialist recruiter is another option when your criteria are difficult to reach. Ask how the recruiter will apply them.
Have a community moderator approve a post before using their space. Invite people to respond privately through an approved channel. Do not scrape a member list or treat access to a customer database as blanket permission to contact everyone.
What should the invitation make clear?
Say who is conducting the research, the task being studied, the session format and expected duration. Describe any incentive and provide a way to ask questions or decline. Avoid recruitment copy that sells the proposed solution before someone has described their experience.
The GOV.UK consent guide recommends an information sheet during recruitment. Explain data collection, observers, recording, use, sharing, retention and withdrawal in a format participants can understand. Keep evidence of what they agreed to. An expression of interest is not consent to record an interview or publish a testimonial.
Before the conversation, confirm continued agreement. Stop if consent is withdrawn and follow the reviewed withdrawal and data-handling procedure. Use our non-leading interview guide for the session itself.
How do you avoid excluding people through the arrangements?
Ask about preferred communication, usable materials and participation support before fixing the format. The participant-finding guide specifically addresses accessible contact methods, communication support and usable consent materials. Offer arrangements appropriate to the person's needs rather than assuming everyone can use a video call.
Do not turn a support request into an unnecessary medical-history questionnaire. If you cannot provide an agreed arrangement, resolve that before confirming the booking. A calendar invitation does not solve an access problem.
What should you decide about incentives?
An incentive needs an ethical plan as well as a budget. The Department for Education's guidance identifies risks including pressure to participate and digital incentives that some people cannot access. Its payment rules are departmental, not universal startup rules.
Our recommendation is to state the amount, form, eligibility and delivery arrangements before booking, after appropriate review. Do not make payment depend on praise, purchase or the answers you hoped to hear. Seek qualified research advice if the proposed incentive could compromise voluntary participation.
How should you manage the recruitment list?
Use a restricted scheduling record with contact details, eligibility status, agreed arrangements and session status. Avoid a shared calendar that exposes other participants' identities. Give the interviewer only the information needed for the agreed session.
The GOV.UK privacy guide recommends minimum necessary recruitment information, secure storage, limited access and deletion when details are no longer needed. Follow a reviewed retention plan rather than keeping every unsuccessful applicant indefinitely. Check third-party recruiter and scheduling-tool arrangements with your privacy adviser.
For research notes, use participant codes and appropriate access controls; a code alone does not make a person's story anonymous. Our interview-analysis guide explains how to separate evidence from interpretation after the sessions.
What if the first invitation gets few responses?
Keep a simple record of the channel, invitation wording, replies, relevant volunteers and completed sessions. These are operational counts, not a market estimate. Before relaxing the criteria, check whether the message reached the intended people and whether the session arrangements were workable.
Change one part of the recruitment plan deliberately and note why. Do not redefine the target participant merely to fill the calendar. A useful round can be smaller than planned if its limitations are visible; an irrelevant round does not become stronger because every slot is occupied.
