Removing Data Silos with a Bottom-up Approach

How a bottom-up data mesh gave a European paytech provider its first full view of the customer.

A leading European provider of digital payment solutions for individuals, businesses, and financial institutions was struggling with slow decision-making because its data lived in fragmented, siloed systems with no unified view of customer interactions. Darize delivered a self-service data platform, built bottom-up with a data mesh approach, to bring that data together without a large-scale program. The result: manual reporting dropped by 70%.

the challenge

Insights limited by fragmented data

The paytech provider struggled with slow decision-making and no unified view of customer interactions.

The company aimed to sharpen its operations with actionable insights by deploying data and AI platforms. Getting there meant working through:

  • fragmented data from diverse sources
  • hidden legacy dependencies
  • siloed systems across the organization

To enable data-driven insights and pave the way for future AI capabilities, the paytech provider needed to transform both its data and its governance. Internal politics meant a large-scale program was not an option, so the work called for an out-of-the-box approach.

the solution
