The challenge

Serasa Experian is Brazil's largest credit bureau. For decades, the company helped banks decide who should receive credit, making it a brand many consumers associated with debt and rejection.

At the same time, more than 60 million Brazilians had a negative credit history, and 90% of digital financial transactions were happening on smartphones.

The opportunity wasn't simply to launch an app—it was to reposition the company from a credit authority into a financial ally that could help people rebuild their financial lives.

My role

I led the UX for the mobile experience, from discovery through validation.

My responsibilities included:

  • Planning and conducting user research
  • Defining user segments and journeys
  • Designing the end-to-end experience
  • Validating prototypes with customers
  • Working closely with product, engineering and data teams

Understanding people's relationship with debt

We combined behavioral data from Experian's database with interviews conducted across Brazil through Serasa's traveling financial assistance program.

One insight became the foundation of the product:

People weren't looking for a credit score—they were looking for a clear path to improve it.

That shifted our focus from displaying financial information to guiding users through achievable actions.

Designing trust

Financial products often overwhelm users with technical language and complex processes.

Instead of building another banking app, we designed an experience centered on education, transparency and progress.

The app helped users:

  • Understand their credit score
  • Renegotiate outstanding debts
  • Track their financial progress
  • Access personalized credit offers when eligible

Every flow was tested and refined with real users before release.

Outcome

  • The product received widespread media coverage
  • Consumer adoption exceeded initial expectations
  • More financial institutions joined the platform with new credit offers
  • Serasa strengthened its relationship with end users by providing value beyond credit reporting
