maconda supports Dutch Sansidor Group with market entry in Germany

maconda-News April 2025
The Sansidor Group, a Dutch specialist for technical testing of buildings and systems, has successfully launched on the German market. This was also made possible by the buy & build strategy developed by maconda: flex|sec and GBS, two experienced providers of electrical safety testing, became the Sansidor Group's first German partner companies on the 1st of April 2025, both identified and secured by maconda.
maconda was closely involved in all phases of Sansidor’s market entry – from analysing several target sectors relevant to safety inspections and initiating transactions. The starting point was a detailed examination of the German market, where inspection services for buildings and technical systems, particularly for electrical devices and systems, fire protection, occupational safety, water hygiene, and air quality, are legally required. maconda’s consultants held numerous discussions with market experts, industry associations and regulatory authorities to identify suitable target companies within the strictly federal structure of the German construction industry, marked by widely varying regulations and responsibilities – a true “needle in a haystack” search.
Companies with a suitable business model were approached, as in the case of flex|sec and GBS and were brought together with Sansidor. A key factor was ensuring that the corporate cultures of the target companies and Sansidor were compatible. The result was a perfect fit that, according to all involved, has been met with great satisfaction.
Last but not least, maconda provided organisational start-up support for Sansidor’s entry into the German market. The consultants worked closely with Bernhard Schwarm, who has been Managing Director of Sansidor Germany since mid-March. “Sansidor’s market entry was a challenging project in which maconda’s strengths came fully into play. We are strong in analysis, highly familiar with niche markets, and rely on a robust network of experts,” explains maconda Managing Director Rainer Mayer. “We are very pleased that we were able to secure two outstanding teams for Sansidor with Flex-sec and GBS.”
Launch in Germany with electrical devices and systems testing
Both flex|sec and GBS are established providers of electrical safety inspections in accordance with DGUV V3. flex|sec focuses on inspecting mobile electrical devices and stationery systems and performs thermographic inspections. GBS specialises in testing mobile devices, fixed installations, welding equipment, ladders, steps, and EV charging stations. Both companies will retain their brand identity and successful teams. As part of the group, they also benefit from administrative support provided by Sansidor Holding, in areas such as tax, legal affairs, recruitment, and marketing. This principle of “buy & build together” is a core element of Sansidor’s strategy and the premise on which maconda helped shape the successful launch in Germany.
