About Us

Skyrocketing together

The origins of Proventis Partners are tied to four independent, established offices located in four financial hubs.

In Munich, Jan Pörschmann and Rainer Wieser founded the Proventis GmbH in 2001. From day one, they focused on accompanying M&A-transactions and Corporate Finance projects. In Hamburg, the independent M&A-boutique Hartmann Zillmer Corporate Finance GmbH arose at the same time through significant involvment of Jost Hartmann. Dr. Christoph Studinka and Teun de Ven began as M&A advisors in Zurich, Switzerland and jointly founded Proventis Partners AG soon thereafter. Since 2017, Dr. Markus Heusser is adding to the partnership here. Ulrich Schneider already stepped aboard in Hamburg in 2010. In 2018, Absolvo joined with 10 professionals in Budapest.
Ten entrepreneurs, one objective: the best result for the client. Even though cooperation between the different offices was limited in the beginning, it became closer and closer over time. While the partners followed the same goals, they also discovered that they feel also obliged to follow the same values such as independence and customer orientation. Since 2010, Proventis Partners operates commonly in the market under one brand and provides inter-locational solutions. The concept is popular with the customers: the number of projects, the transaction volume and the number of employees increase continuously.

Our home is at some of the most important economic hubs in Europe

Based in German-speaking Regions of Europe, Proventis Partners operates form its offices at four different locations. From Hamburg, Munich, Zurich and Cologne, a team of approximately 30 professionals works on national and international projects. The clients profit likewise from the regional proximity as well as the international network of our partners. In Eastern Europe, Proventis Partners is present through Absolvo with its office in Budapest. 
Local presence ensures proximity and a deep understanding of the requirements, especially of medium-size customers. Being located at important hubs enlarges the spectrum for potential partners in a transaction and facilitates contacting international buyers or sellers. We know: the business of M&A is a global one. Hence, it is advantageous that our team speaks 10 different languages.
