How we came to be

DEGIRO B.V. was founded in Amsterdam on June 3rd, 2009. In 2020, over a decade later, the Dutch DEGIRO B.V. was bought by the German flatex AG. In May of 2021, the two companies officially merged, becoming flatexDEGIRO Bank AG. flatexDEGIRO Bank AG still operates as two separate brokers in their respective marketplaces under their brand names flatex and DEGIRO. The merger allowed us to combine our experience and expertise and grow to be Europe's leading broker.

Internal and external supervision


To ensure comprehensive oversight of our operations, we have implemented a governance structure consisting of three tiers.

First and foremost, the Dutch Branch of the flatexDEGIRO Bank has its own Branch Management. The Branch Management consists of three Branch Managers and is responsible for the day-to-day operations of DEGIRO. Within the Branch Management team, there is a clear division of responsibilities, with each of the Branch Managers having their own focus points.

DEGIRO’s Branch Management reports to Frank Niehage in his function as CEO of flatexDEGIRO Bank AG. The Board of Directors of flatexDEGIRO Bank AG is responsible for the day-to-day management and long-term strategy setting of the company. When it comes to setting the strategy of DEGIRO, the Board of Directors works in close cooperation with the Branch Management.

Finally, the Board of Directors is overseen by the bank’s Supervisory Board. The Supervisory Board is responsible for supervising and advising the Board of Directors.


flatexDEGIRO Bank Dutch Branch, trading under the name DEGIRO, is the Dutch branch of flatexDEGIRO Bank AG. flatexDEGIRO Bank AG is primarily supervised by the German financial regulator (BaFin). In the Netherlands, flatexDEGIRO Bank Dutch Branch is registered with DNB and supervised by AFM and DNB.
