For international product, design and research teams

Learn how your product is experienced in Brazil

We help global product, design and research teams understand how their product is experienced in Brazil: we recruit and verify the right participants, run the research in Portuguese, and bring back findings in English with the cultural context behind them.

In practice: interviews, usability tests and service walkthroughs with people in Brazil who use, or could use, your product or service.

No time or local resources to recruit participants in Brazil? That's usually where studies stall. We take that part off your plate, and stay with you through the research itself.

Local language matters. So does understanding the context behind what people say and do.

From participant recruitment and screening to Portuguese-language research and English-language findings, yUserLab helps your team learn from Brazilian users without losing the cultural and behavioural nuances that inform better decisions.

  • Recruit and screen participants against your study criteria, across Brazil's regions and profiles, with first participants within days.
  • Conduct research in Portuguese, with language and cultural support that goes beyond literal translation: expressions, regional differences and social norms.
  • Understand local behaviours, expectations and decision-making contexts.
  • Receive findings in English, with cultural context and actionable insights.
  • Go further with service design: map journeys and touchpoints and shape how your service should work for people in Brazil.
  • Leave incentives to us: we pay participants locally and send you a single invoice.

Consultancies and agencies: running a study for a client with users in Brazil? We can handle recruitment, Portuguese-language fieldwork and incentives as part of your project.

Para empresas brasileiras

Sua empresa quer crescer em outros mercados? Comece entendendo as pessoas.

Expandir para outro país exige mais do que traduzir um produto ou adaptar uma comunicação. É preciso compreender como as pessoas vivem, escolhem, compram e utilizam soluções naquele contexto.

A yUserLab ajuda empresas brasileiras a investigar novos mercados por meio de pesquisa com pessoas locais, identificando necessidades, expectativas, comportamentos, critérios de escolha e possíveis barreiras à adoção.

  • Compreender consumidores em mercados internacionais.
  • Investigar necessidades, hábitos e critérios de decisão.
  • Identificar diferenças culturais e barreiras de adoção.
  • Transformar descobertas em insights acionáveis para decisões de produto, serviço e expansão.

Better research starts with understanding people in context.

People do not experience products and services in isolation. Their decisions are shaped by needs, expectations, habits, culture and everyday circumstances.

yUserLab aims to bring these local perspectives into research so companies can move beyond assumptions and make better-informed decisions.

Grace Coelho, PhD

Founder of yUserLab and Coelho Strategy

  • Senior UX Researcher
  • Cross-market user research
  • Financial Services, Health, EdTech & AI
  • EN/PT

Grace has spent 13+ years working across startups, UX and digital products. Her doctoral research deepened her practice in generative and evaluative research methods, strengthening her ability to understand people’s needs, behaviours and decision-making with rigour.

yUserLab helps global enterprises understand Brazilian users beyond the language. The service combines culturally informed research design, participant screening against study criteria, and Portuguese-language research with local context and behavioural nuance.

Grace’s focus goes beyond gathering responses: she connects what people say and do to what it means for the business, translating locally grounded findings into clear, actionable recommendations that help teams make better product decisions.

Because research creates value not just when you understand people, but when that understanding changes what you do next.

Clients’ strategic studies are kept strictly confidential, for reasons of ethics and research rigour.

Fundadora da yUserLab e da Coelho Strategy

Grace tem mais de 13 anos de experiência com startups, UX e produtos digitais. Sua pesquisa de doutorado aprofundou sua prática em métodos de pesquisa generativos e avaliativos, fortalecendo sua capacidade de compreender com rigor as necessidades, os comportamentos e as decisões das pessoas.

A yUserLab ajuda empresas globais a compreender usuários brasileiros para além do idioma. O serviço combina desenho de pesquisa culturalmente informado, triagem de participantes de acordo com os critérios do estudo e pesquisa em português com contexto local e nuances comportamentais.

O foco de Grace vai além de coletar respostas: ela conecta o que as pessoas dizem e fazem ao que isso significa para o negócio, transformando descobertas fundamentadas no contexto local em recomendações claras e acionáveis, que ajudam equipes a tomar melhores decisões de produto.

Porque a pesquisa gera valor não apenas quando entendemos as pessoas, mas quando esse entendimento muda o que fazemos a seguir.

Os estudos estratégicos dos clientes são mantidos em estrita confidencialidade, por razões éticas e de rigor da pesquisa.
