Since the company was founded in 1993 by Kurt Krueger it has never lost its power to design innovative products for the consumer market and for industrial companies. Well known manufacturers all over the world from Asia to the United States put their trust in KSE’s products and we are glad and proud of this fact.

KSE started its business with the development of a range of database desktop software products for area and bank codes called PLZDirectory and BLZDirectory as well as an address book software. Furthermore, when Microsoft announced the windows mobile operating system, we saw the opportunity to support Windows CE - later Windows Mobile - with a comprehensive range of products in very different segments, such as KSE Abacus XT a calculator app, the KSE Entertainment Pack which was - amongst other things - sold via Medion a reseller of Aldi, and many more.

Another important milestone was the success of a mobile fax solution KSE Truefax which enabled the user to send and receive faxes from a mobile device. This was a novum at this time and companies like HTC, Telekom, Vodafone and other big players deployed KSE Truefax on their mobile devices.

We now focus to support the Apple operating systems with a wide range of products for the iPhone and iPad, macOS and tvOS with innovative consumer and client-oriented products.
