That is why we support players who champion sustainable development. As a reliable partner providing effective communication, we ensure that they advance quickly and efficiently.

We offer high-calibre communication services and personal, flexible service. Our services range in subject from strategic communication consulting, brand management and corporate design to the creative implementation of online communication measures (web and social media), corporate publishing, media relations and dialog marketing.

Strategic development

Polarstern enhanced its business model by adding new services. The agency relied even more heavily on effective communication for com­mit­ment to sustainability and sought to deepen its collaboration with the clientele. In the future, cli­ents were to be closely assisted at any time all year round. New cli­ents included rommelag, Kurszen­trum Ballenberg, LerNetz and PostFinance.

Second business location

In May, Polarstern opened its sec­ond business location in So­lo­thurn. It became the first Swiss com­mu­ni­ca­tion agency to agree to provide the UN with free services every year equivalent in value to ten per­cent of its annual sales and to offer services at reduced rates to or­ga­ni­sa­tions and companies com­mitted to sustainable de­vel­op­ment. Fol­low­ing a strategic analysis, a com­pre­hen­sive com­mu­ni­ca­tion plan and brand development, the cus­tom man­u­fac­tur­er Emerell en­trusted Polarstern this year with the entire implementation of its com­mu­ni­ca­tion measures.

Sustainable development

Polarstern recognised the need for communication services on the subject of sustainability. Just re­cent­ly, the agency began assisting the Swiss Federal Office of Public Health with communication about NPEB, the national nutrition and exercise program that forms part of the sustainability strategy of the Swiss Federal Council. On behalf of the corporate responsibility team at Swisscom, Polarstern also closely followed Bertrand Piccard’s solar flight adventure aboard the Solar Impulse. At the end of the year, Andreas Renggli acquired all orig­i­nal shares in the company from the previous co-owners.

Strategic consulting

This year Polarstern began offering consulting services in strategic com­mu­ni­ca­tion. On 1 June 2009, the agency moved its business prem­ises from Schönbühlring 5 to Löwenplatz 5 in Lucerne. There it began sharing office space with the communication studio Mixer and the cinema Stattkino. It became a collective member of the regional association for PR professionals ZSPR and forged cooperation ar­range­ment with Walker Man­age­ment AG (Lucerne and Sursee) and the agencies ProjektForum (Bern) and Flow Relations (Zug).

Business idea implemented

In his master’s thesis, Andreas Renggli defined and described for the first time communication co­op­er­a­tion arrangements between media companies and open-air music festivals in Switzerland. The insights from this empirical study were incorporated into his business idea. On 24 November 2006, Polarstern GmbH was formally established as a Lucerne com­mu­ni­ca­tion agency.

Vision of modern media work

Andreas Renggli developed the pro­to­type for Emerlet, an elec­tron­ic media relations man­age­ment tool in collaboration with Tobias Henz from Bern Uni­ver­si­ty of Ap­plied Sciences. They entered it in a competition for young en­tre­pre­neurs but did not win an award.

Step 1

At Bern University of Applied Sci­ences, Andreas Renggli, Thomas Gygax, Philip Ritschard and Ralph Eli investigated how information and communication technologies (ICTs) could be used for media work and what significance net­work­ing might attain in the future in these two areas. The study met with great interest. More than 100 professionals took part in the study. The idea of Polarstern as an agency and platform for client proj­ects was born.
