PREMA GmbH was founded by Karl Marti in Oftringen in 1976. It was and remains the only company in Switzerland to develop and manufacture systems for counting and sorting coins. From the outset, PREMA machines enjoyed great popularity domestically and abroad thanks to their precision and longevity.


The qualified engineer Rudolf Stöckli took over management of the company from his father-in-law Karl Marti in 1981. With great dedication and foresight, the married couple Rudolf and Trudi Stöckli went on to successfully and consistently expand the company. It was possible to set a path-breaking milestone in 1987 with the development and production of the first self-service system for the depositing of coins. Furthermore, the range was supplemented on a step-by-step basis with systems for cash handling from renowned suppliers.


In autumn 2011, Rudolf and Trudi Stöckli passed the torch of the family company on to their daughter Natalie and her husband Marco Steinmann, who had both managed the sales department of the traditional company with success for years.
