Key people at CalWin A/S.
CalWin A/S is an Odense, Denmark-based technology company that develops vertical software solutions and specialized industry calculation systems for the professional installation sector. The organization provides licensing and related support services to a broad customer base that includes sanitation technicians, electrical installers, engineering contractors, suppliers, and wholesale distributors. Operating primarily across Denmark, Greenland, and the Faroe Islands, the business maintained a workforce of 20 employees to manage its regional operations and software development initiatives. After operating as an independent market leader in Danish installation software for over two decades, the company was officially acquired by the Nordic enterprise software group EG A/S in October 2019. Following this transaction, the software platform was fully integrated into the acquirer's broader portfolio of construction technology operations. CalWin A/S was founded in 1996 by Carsten Rasmussen and Kenneth Dreymann.
Key people at CalWin A/S.
CalWin A/S is a Danish software company specializing in industry-specific software solutions for the installation sector, particularly serving sanitation and electrical installers, engineering contractors, suppliers, and wholesalers. The company builds vertical software tailored to the unique needs of the installation industry, helping its clients streamline calculations, project management, and operational workflows. With over 20 years of market leadership in Denmark and presence in Greenland and the Faroe Islands, CalWin has established strong customer relations and a reputation for deep sector knowledge. Its software addresses the complex challenges of the installation industry by providing specialized tools that general ERP systems do not cover, thus solving inefficiencies and enhancing productivity for its users[2][4].
Founded in 1996 by Carsten Rasmussen, CalWin emerged from a need to develop software solutions that cater specifically to the installation industry's requirements. The founder's background and deep understanding of the sector helped shape CalWin’s focus on delivering industry-oriented software. Over the years, the company grew steadily, gaining early traction through strong customer relationships and becoming a market leader in Denmark. In October 2019, CalWin was acquired by EG A/S, a Scandinavian software group, which has enabled further development and expansion of its solutions under a larger corporate umbrella while retaining its specialized focus[2][4][5].
CalWin operates within the niche of vertical software solutions, riding the trend of industry-specific SaaS platforms that address unique operational challenges better than generic software. The timing of its acquisition by EG aligns with a broader market consolidation and digital transformation push in the construction and installation sectors. Market forces such as increasing demand for digital tools in traditionally manual industries and the need for integrated, cloud-based solutions favor CalWin’s growth. By providing specialized software, CalWin influences the broader ecosystem by enabling installation companies to modernize and compete more effectively in a digitizing economy[2][5][7].
Looking ahead, CalWin’s integration with EG positions it well for scaling beyond Denmark into other Nordic and European markets. Trends such as increased digitalization in construction and installation, cloud adoption, and demand for tailored SaaS solutions will shape its trajectory. Continued investment in product development and leveraging EG’s network could see CalWin evolve into a leading pan-Nordic software provider for the installation industry. Its influence is likely to grow as more companies seek specialized, efficient software to meet complex industry demands, reinforcing CalWin’s role as a key enabler of digital transformation in this sector[2][5][7].
