B2C Case Study
Gen Z Social Commerce in Brazil (Mobile-First)

What the client needed
400 Brazilian 18–27-year-olds who buy through social platforms: how they discover, who influences them, and how in-app checkout actually happens.
Why it was hard
Gen Z attention spans, high fraud in social-recruited traffic, Portuguese-language requirements, and 8 days to do it in — with quality standards that rule out shortcuts.
How we ran it
- Phone-only design: Thumb-friendly layouts, visual scales, 12-minute LOI.
- Native questionnaire: Written with Brazilian Portuguese researchers, not translated after the fact.
- Fraud screening for social traffic: Fingerprinting and behavior checks tuned for the source.
- Paced for completion: Short blocks with progress cues instead of a wall of questions.
Results
Target: Brazil, 18–27, social-commerce buyers.
Completes: 400. Incidence: 35%. LOI: 12 minutes. Field: 8 days.
Low drop-off, clean data, and a clear map of discovery triggers and creator influence for the client's Brazil plans.
