Case 1: Bacen + Reclame Aqui Analysis

Most financial institutions read complaints as operational noise. I read them as a growth opportunity map. Every dissatisfied customer is a customer another bank can capture if it understands the right reason, at the right moment, with the right offer.

The Central Bank publishes quarterly a complaint ranking per institution, with standardized classification. Reclame Aqui continuously publishes complaints in free text, written by the customer themselves, identified by institution. Cross-referencing the two with semantic classification via LLMs, it's possible to map where customer experience drifts from regulatory standards — and more importantly, where the next competitive opening lives. Not hypothesis: it's what customers are literally saying, at scale.

The full dashboard delivers this reading institution by institution: what's going wrong, at what volume, compared to whom, and what that opens as a growth opportunity for competitors and for the institution itself if it wants to close the gap.
