A leading FMCG client needed nationwide product testing across Bangkok and four regional markets — combining CLT sessions with street intercept interviews to validate consumer response across both controlled and real-world environments, at a budget well below standard agency rates.
To cut CLT venue costs, we rotated testing locations between community halls, university facilities, and local government venues — reducing venue spend by up to 35% versus hotel rates. Street intercept sessions ran in parallel at high-footfall locations surrounding each CLT venue on the same days, eliminating duplicate mobilization costs entirely.
For street intercept, we deployed an AI-assisted pre-screening system that digitally profiled and flagged target respondents before interviewers approached them — cutting disqualification rates by over 50% and significantly lowering cost-per-completed-interview across all locations.The combined approach delivered 600 CLT evaluations and 400 street intercept completes across five cities — at a total project cost 30 to 35% below the client's initial quote.
