German PR firm Oliver Schrott Kommunikation (OSK) has acquired a majority stake in Berlin digital shop Compuccino, as the country's fourth-largest PR firm seeks to broaden its offering. The deal will see Compuccino continue to operate as an autonomous agency under OSK's ownership, with founders Klas Roggenkamp and Nader Cserny retaining their roles as managing partners. Founded in 2007, Compuccino employs 20 staffers and focuses on digital content and media, developing apps, tools and digital processes for publishers, political parties, associations and companies. After reporting fee income of around €17m in 2013, OSK moves beyond €18m upon completion of the deal, consolidating its position as Germany's fourth-largest PR firm behind Media Consulta, FischerAppelt and Hering Schuppener. The deal also adds a Berlin presence to OSK's existing network, which includes an HQ in Cologne and additional offices in Stuttgart, New York and Beijing. The addition of Compuccino swells OSK's headcount beyond 150 employees across this footprint. “Building on our initial experience in traditional PR, in recent years we have focused on developing the platforms for telling our clients’ stories," said OSK founder Oliver Schrott. "After establishing multidimensional communication, moving images and social media, we are now investing in compuccino to further extend our digital skills and build a platform for creating entirely new communication formats for our clients by bringing together expertise in content, journalism and technology." OSK's clients include  include Daimler AG, for which the firm serves as lead international PR agency for the Mercedes-Benz and smart brands, along with Michelin, Bosch, Harman, ThyssenKrupp, Tetra Pak, Freudenberg and digitalSTROM.
