An international family business


Sign expertise since 1949

In its more than 70-year history, the Marahrens Group, headquartered in Bremen, has developed into an internationally active, medium-sized company for signs, signage and signage systems. On land or in the maritime sector, all requirements are met: From simple fire extinguisher signs to digital information and guidance systems.


After the end of the Second World War and having successfully completed his training as an engraver, Heinrich Marahrens founded today’s Marahrens Group in 1949 in his parents’ living room in Bremen-Lesum. At that time, the product portfolio essentially comprised branding irons and small engraved signs.


In 1953, the company moved into its own business premises in Bremen-Walle and later in Gröpelingen. In 1982, Heinrich Marahrens handed over the management of the company to his daughter Janina Marahrens-Hashagen and remained active in the company until 1998. He was instrumental in the construction of the new headquarters in Bremen-Grambke.


After taking over the management, Janina Marahrens-Hashagen started with around 25 employees. Together, they expanded the existing business areas, developing new areas which lead to the structure of the company as it is today. Through investments and the personal commitment of the entire team, the company was able to develop to a team of over 200 employees.


In 2017, the third generation joined the family business with the grandson of the founder, Jan-Christian Hashagen. In the same year, the first steps towards internationalization were taken with expansion into the USA and Finland. After establishing itself in the respective markets, the next step was taken in the Baltic States in 2023 with a shareholding in sign manufacturer Adfactory in Estonia.
