WHO WE ARE

Financial services are moving fast towards full digitalization. One of the most important catalysts for that has been fintech enablers and infrastructure. Consumers can now compare, apply and subscribe to a full set of financial services online including legacy products such as insurances, loans, car rentings, or even mortgages.

Access to relevant, accurate and actionable data from applicants at speed is the pillar to meet both consumers and financial services needs.

At Bankflip we are building the rails to collect, process and share financial, employment and other relevant data in real-time, securely and automatically directly from third parties’ products.

Our smart open data solution combines a robust yet simple API with a suite of low-code and no-code tools to help our customers (the new wave of fintechs, proptechs, insurtechs, tax management companies in Europe) collect and digest the necessary data from their users within their apps, communication channels and operations.

Founded by 3 experienced entrepreneurs in fintech and digital banking, and backed by top-notch national and international investors (including JME, Draper B1, Notion Capital and serial fintech entrepreneurs), Bankflip aims to create a new business standard for financial services, much more transparent, fair and closer to the end-user.
