Open Banking Stories: Real-World Deployments

Real-world deployments from banks and fintechs—from AI in open banking to instant savings funding and faster mortgage decisions.

Banks and fintechs are putting open banking to work in production—from AI-powered money assistants to instant savings funding and faster lending decisions. Below are selected stories with short summaries and links to the original sources.

bunq and Mastercard

bunq became the first bank in Europe to leverage AI in open banking with Mastercard. Europe's second-largest neobank (12.5 million users) integrated Mastercard's Open Banking platform so customers can link accounts from multiple banks in the bunq app. The partnership includes bunq's generative AI assistant Finn, which uses transaction data across those accounts to answer questions (e.g. spending on coffee or restaurant visits). The features launched in the Netherlands, France, and Germany; nearly 40% of surveyed users reported a significant increase in app usage within two weeks.
