History

The company's origins trace back to the Deutsche Bau- und Bodenbank AG, founded in 1923. In 1957, the bank established a data processing center, which evolved into an IT service provider for the property industry.
During the 1990s, the company expanded by acquiring solutions like WohnData and restructured, spinning off its IT services division. In 1999, it became DePfa IT Services AG, marking the beginning of its international expansion.
In 2002, following the split of its parent company, the firm was renamed Aareon AG and became a wholly owned subsidiary of Aareal Bank. Throughout the 2000s, Aareon expanded its product portfolio through a cooperation with SAP AG and a division swap with Techem, which added the WODIS ERP system. By 2009, it had become the market leader in France through a merger of local subsidiaries.
The 2010s were marked by significant international growth, including the acquisitions of companies in the Netherlands, the UK, and Scandinavia. In 2015, the company launched its Aareon Smart World platform.
In 2020, Advent International acquired a 30% stake in Aareon from Aareal Bank. The company accelerated its acquisition strategy, purchasing numerous companies across Europe, including CalCon and wohnungshelden in Germany, Fixflo in the UK, and Momentum Software Group in Sweden. In 2023, it launched its "Aareon Connect" partner program to integrate third-party solutions.
