Nordigen has helped European consumer lender Novum Bank achieve a 14 percentage point GINI improvement in Spain. 

In 2016 Novum Bank set out to improve their scorecards in Spain for their consumer lending product. The bank's biggest underlying challenge was understanding the spending behaviours of their so-called 'thin-file' customers or clients with incomplete or non-existing credit histories. Novum Bank turned to Nordigen to test how insights from customer account information could solve the problem.

Over the course of four weeks, Nordigen and Novum Bank's Data Science team tested Nordigen's transaction categorization and behavioural scoring engines. The tests sought to determine whether they improved the overall accuracy of Novum Bank's scoring models. 

The results revealed a 14 percentage point GINI coefficient uplift on top of all other existing data sources, including credit bureau data. The achieved results were sufficient to add Nordigen data points to Novum Bank's scorecard. 

Filip ten Bruggencate, Head of Portfolio Strategy at Novum Bank Group added that “Nordigen categorization adds significant value to our bank transaction data reports, by making them much easier to interpret. The categorization saves us significant time in contrast to finding out what each transaction means on our own.”

“Novum Bank is on the cutting edge of technology and it is fascinating to work with their data science team. We strongly believe that the future of credit scoring is in the ability to leverage the opportunities of open banking. Our partnership with Novum Bank is a great example of this.”
