Dashboard Portal as a data product

Problem

Power BI license cost (R$45 per user) made it unfeasible to scale BI to all of the fintech's clients. Every new client increased cost linearly, limiting the platform's reach.

Solution

• Databricks Lakehouse as a single trusted data layer (Bronze→Silver→Gold).
• Custom Dashboard Portal serving visualizations straight from the Gold layer.
• Replaced individual Power BI licenses with portal-based access.
• Standardized governance and quality to ensure trust in the numbers.

Results

• Cost per user dropped from R$45 to R$5 (~9x reduction).
• Portal extended to 500+ company clients.
• What used to be a cost became a revenue-generating data product.
