Face-to-Face Research (CAPI)

Face-to-face fieldwork reaches populations that no remote method can, and it is also the method where quality assurance matters most, because the interview happens out of sight.

We answer that with supervision: accompanied visits, GPS and timestamp capture on every interview, and back-checking by a team that did not collect the data.

  • In-store, street and door-to-door intercept fieldwork
  • Central location testing and hall tests
  • GPS and timestamp verification on every interview
  • Field supervisors accompanying and auditing interviewers

Our capabilities

What our face-to-face research (capi) service covers

We own the workflow end to end, which is what makes a single point of accountability possible rather than just claimable.

Intercept fieldwork

In-store, shopping centre and street intercepts with sampling rules that produce a defensible sample rather than whoever was easiest to stop.

Door-to-door surveys

Household fieldwork with random route or listed-sample designs, used where general population coverage cannot be achieved any other way.

Central location testing

Hall tests and product testing under controlled conditions, including venue sourcing, set-up and stimulus handling.

GPS and timestamp verification

Every interview carries location and timing metadata, which is checked against the sampling plan before the data is accepted.

Supervised field teams

Field supervisors accompany interviewers on a defined share of shifts, and the same supervisors are accountable for the market's data.

Stimulus and material handling

Printing, shipping, customs documentation and secure handling of confidential concept material, managed as part of the project rather than left with you.

Included in every project

Standard on every engagement, not an upgrade

The same six things are included whichever service a project starts from. They are the reason our quotes look like they do.

Screening design

We work through your screener with you before fieldwork opens — quota alignment, incidence estimation and disqualification logic, agreed in writing.

Multi-source recruitment

Our own panel across core markets plus a vetted partner network reaching 35+ countries. No single source carries a project; diversity of sourcing is what keeps the sample honest.

Layered quality assurance

Screener validation, digital fingerprinting against duplicates, automated response scoring, analyst review and post-field back-checking where the study calls for it.

Confirmation and scheduling

Reminder workflows for qualitative work, with standby replacements held as standard so a no-show does not become a gap in your data.

Incidence reporting

Funnel data and incidence rates before and during fieldwork, so a feasibility problem reaches you while there is still time to act on it.

A named project manager

One person accountable from brief to delivery, with daily field updates — not a shared inbox and not a ticket queue.

FAQ

Frequently asked questions — face-to-face research (capi)

Which markets do you run CAPI in?
More than twenty, concentrated in South and Southeast Asia, the Middle East, Africa and Eastern Europe, where face-to-face remains the dominant method. Ask about a specific market and we will tell you honestly whether we are strong there.
How is fieldwork verified?
GPS and timestamp capture on every interview, accompanied supervisor visits, and back-checking of completed interviews by a separate quality team.
Can you handle confidential stimulus material?
Yes, including numbered material, signed interviewer undertakings and return-and-destroy protocols for pre-launch concepts.
What sample sizes are practical?
From a few hundred interviews in one city to multi-thousand national samples. The constraint is usually timeline and interviewer availability rather than sample size.
