An international success story made in Saxony


Founded in 1990 in Vogtland, Saxony, GK Software has been one of the most successful growth stories in the German software industry ever since.




From local to global –
an international success story


Founded in 1990 in Vogtland, Germany, GK Software has become one of the most successful growth stories in the German software industry. Our focus is on proprietary technology solutions that address the challenges of the world's leading retailers. With more than 570k retail and payment installations in over 60 countries and on every continent, GK is a true global player made in Saxony.

In 2023, GK entered into a strategic partnership with the Japanese technology group Fujitsu. Under the partnership, GK and its more than 1,200 employees will remain independent and continue to pursue their entrepreneurial goals. At the same time, the partnership creates significant growth opportunities for both sides, which will be jointly pursued to develop an even more robust ecosystem for unbeatable trading technology that is innovative and sustainable.




What makes us different

We provide platform-independent, actionable solutions for global growth, innovating to give leading retailers greater flexibility.

We develop solutions based on the latest technologies and open standards that are currently used by more than a quarter of the world's top 50 retailers. Our extensive solution expertise helps retailers achieve greater flexibility and faster decision making in business-critical projects.

At the heart of our portfolio is GK CLOUD4RETAIL - a fully cloud-based and open full-service platform for scaling a modern retail business. Retailers benefit from unmatched speed and highly secure operations that seamlessly integrate AI applications such as personalization and dynamic pricing.

Since GK was founded in 1990, we have been empowering retailers to solve process-critical challenges. We have always been committed to system openness, partnership and innovation. This is why we were the first to use the new Java technology in 1997, sought a strategic partnership with SAP in 2001, and launched the first enterprise retail solution from the cloud in 2018. Thanks to the acquisition of GK AIR (formerly prudsys), we are now one of the few companies that can offer its customers proven AI solutions that are used in the market. With Deutsche Fiskal, we are also able to cover the highly complex topic of fiscalization in our solutions quickly and in compliance with the law, significantly accelerating the time-to-market of our customers worldwide.



Our journey continues

Global leaders in retail rely on GK to achieve their mission-critical goals - locally and internationally.

GK's growth story continues at a rapid pace and across the globe. Today, GK has a presence on every continent, and its global footprint with offices around the world allows it to work closely and directly with customers on local solutions that have the potential to scale globally.

With the help of our network of strategic partners, we help drive expansion projects in all markets and use innovative solutions to make the entire consumer journey new, more sustainable and experience-optimized.

We actively work with public, political and business leaders to improve local infrastructure and create education and training programs that promote opportunities for work and prosperity in regions outside of global metropolitan areas. We are committed to responsible technology applications that contribute to a more sustainable and equitable society for all and are actively involved in relevant associations, bodies and committees.
