Müller Medien

What Müller Medien does

Müller Medien is a family-owned, Nuremberg-headquartered media company founded in 1950 that operates as a federation of more than 100 partner companies across 26+ domestic and international locations. The group spans publishing (notably TESSLOFF Verlag and the WAS IST WAS brand, which has sold over 100 million copies), SME digitalization services (SELLWERK with 150,000+ members), freelancing platforms (freelancermap), broadcasting (over 40 years as a pioneer in German private radio and television), and healthcare/directory digital assets built through a sustained acquisition program from 2014 onward.

The company's product portfolio combines legacy media IP (children's book publishing, radio/TV channels) with operating platforms that aggregate and serve Germany's small and medium enterprise (SME) segment. Under the "müller x net" framing, the group functions as an "international family of companies" connecting more than 200,000 SMEs across its network, with technology stack investments in SME digital marketing tools, online directories, and — most recently — an investment in Mozaik, an AI-powered corporate video platform.

Revenue mechanics are diversified across publishing royalties and book sales, subscription/membership fees from SELLWERK's 150,000+ member base, advertising across broadcasting and digital properties, and platform/directory monetization through acquired healthcare and digital directory assets (ARZTE.DE, Arzttermine.de, FAIRRANK, Portal United, DS Digitale Seiten, Kyto). Go-to-market is primarily B2B for SME digital services and B2C for publishing, with continued M&A as a core inorganic growth lever led by a dedicated Head of New Business / M&A function.
