Overview
GK Software is a German retail technology company headquartered in Schöneck/Vogtland, Saxony. It develops software and related services for the operation of large retail organizations, including supermarkets, hypermarkets, specialty retailers, wholesale businesses, and other multi-site merchants. Its systems cover front-end point-of-sale operations as well as store administration, merchandise processes, promotions, vouchers, electronic labels, device control, monitoring, and cloud-based retail platforms. The company was established in 1990 as G&K Datensysteme GmbH by Rainer Gläß and Stephan Kronmüller. The GK name derives from the founders' initials. After more than a decade of expansion, the business was converted into a stock corporation in 2001 and entered the Prime Standard of the Frankfurt Stock Exchange in 2008. Its public-market period supported further acquisitions, international expansion, and the development of a broader retail software portfolio. GK expanded through a series of strategic transactions. It acquired Solquest GmbH in 2009 and the AWEK Group in 2012, strengthening its retail services and technology capabilities. In 2015 it acquired the retail business of US point-of-sale specialist DBS Data Business Systems Inc. In 2017 it announced the acquisition of a majority interest in prudsys AG, a company focused on real-time personalization and artificial intelligence for retail. Prudsys later operated within the group under the name GK Artificial Intelligence for Retail AG. The company has also maintained a close commercial relationship with SAP. SAP initially assumed distribution of two GK products in 2009; the relationship subsequently expanded to five products distributed globally from 2013. In 2020, GK announced a technology partnership with Kronos Incorporated to integrate the Workforce Dimensions suite with its OmniPOS platform. GK also established retail7 GmbH in 2020 to develop a cloud point-of-sale product aimed at small and medium-sized businesses. GK's cloud strategy is represented by GK CLOUD4RETAIL, a modular platform covering point of sale, back office, merchandise management, promotions, vouchers, store-device control, electronic or automatic label printing, monitoring, and open-scale functionality. The company also operated Deutsche Fiskal GmbH, founded in 2019, which provided open cloud services meeting German fiscalization requirements. Deutsche Fiskal left the GK Group on April 1, 2025, after being acquired by Austrian company fiskaly GmbH. In January 2025, GK acquired Nomitri GmbH, a deep-tech and computer-vision company developing visual artificial-intelligence applications for self-checkout. The transaction extended GK's business into computer vision and checkout automation. In 2023, Fujitsu ND Solutions AG became GK Software's strategic investor and majority shareholder. Michael Scheibner became CEO and chairman of the executive board on June 1, 2023. Following the ownership change, GK Software shares were delisted from the Frankfurt Stock Exchange and other German stock exchanges at the end of August 1, 2023. The company maintains branches in Germany and several international markets. According to the cited Wikipedia article, GK Software had approximately 1,258 employees across fifteen locations and revenue of EUR 172.5 million in 2023. These figures are historical reference data rather than current operating guidance.
History
GK Software began in 1990 in Schöneck/Vogtland as G&K Datensysteme GmbH, founded by Rainer Gläß and Stephan Kronmüller. The company's name reflects the initials of its founders. Its initial focus was software for retail operations, an area that requires highly reliable transaction processing, store-level systems, merchandise data, and centralized administration across large branch networks. After a period of growth, the company was converted into a stock corporation in 2001. It later pursued a public-market strategy, entering the Prime Standard of Deutsche Börse in 2008. The listing provided a platform for expansion and acquisitions, while the company continued to position itself as a specialist supplier to large retailers rather than as a general-purpose software vendor. In 2009, GK acquired Solquest GmbH. That year it also entered a distribution arrangement with SAP covering two products. The commercial relationship grew over time to five products and, from 2013, involved global distribution. In 2012, GK acquired the AWEK Group, reinforcing its services business and broadening its ability to support retail customers with implementation and operational expertise. The company continued its international expansion in 2015 through the acquisition of the retail segment of DBS Data Business Systems Inc., a US point-of-sale software specialist. In 2017, GK announced that it would acquire a majority interest in prudsys AG, based in Chemnitz and Berlin. Prudsys specialized in real-time personalization for retail and used artificial intelligence to support individualized offers and customer experiences. From September 2022, prudsys operated within the group as GK Artificial Intelligence for Retail AG. GK increasingly emphasized cloud delivery and a broader platform approach. Its GK CLOUD4RETAIL portfolio brought together point of sale, back office, merchandise management, promotions, vouchers, store-device control, label printing, open-scale functionality, and monitoring. In 2019, GK founded Deutsche Fiskal GmbH to develop and operate an open cloud solution supporting German fiscalization requirements. In 2020, it founded retail7 GmbH, which focused on a cloud point-of-sale system for small and medium-sized companies. GK also announced a partnership with Kronos Incorporated in January 2020 to integrate Workforce Dimensions with OmniPOS. The group's ownership and capital-market structure changed substantially in 2023. Fujitsu ND Solutions AG became GK Software's strategic investor and majority owner. Michael Scheibner was appointed CEO and chairman of the executive board, effective June 1. The company's shares were subsequently delisted from the Frankfurt Stock Exchange and other German stock exchanges at the end of August 1, 2023, ending approximately fifteen years as a listed company. GK continued to extend its technology portfolio after the ownership transition. On January 10, 2025, it acquired Nomitri GmbH, a deep-tech and computer-vision company developing visual artificial-intelligence solutions for self-checkout. Separately, Deutsche Fiskal ceased to belong to GK on April 1, 2025, when fiskaly GmbH acquired the company. GK therefore combines a long-established retail software business with newer activities in cloud computing, personalization, artificial intelligence, and checkout automation.
