Gert-Maria Freimuth and Dr Christof Nesemeier founded Nesemeier & Freimuth GmbH in Berlin in 1995. The idea had already been born in 1988 when they were studying in Münster. In 1997, the two used their company to take over MBB Gelma Industrieelektronik GmbH – a former subsidiary of the Messerschmitt-Bölkow-Blohm group – from Daimler-Benz Aerospace AG. It was from that point on that the abbreviation MBB was incorporated into the company name. The company issued its IPO in 2006, and this was followed by a switch to the Prime Standard on the Frankfurt Stock Exchange in 2008. In 2023 the company has more than 3,700 employees. The founders have remained majority owners of the company since the flotation.
