New faces on the Supervisory Board

Portal Systems also welcomes two new members to its Supervisory Board: André Hoseas and Mario Dönnebrink.
André Hoseas is the founder of Portal Systems, was CEO from 2018 to 2021 and retired from the operational business in 2021. He brings more than 20 years of experience with Portal Systems to the Supervisory Board, making him an important and experienced source of advice and ideas for the Management Board.
Mario Dönnebrink worked for d.velop AG for a total of 19 years until March 2022, including many years as a member of the Management Board and most recently as Chairman of the Management Board. During this time, he developed the company into one of the leading providers in the field of document management and consistently geared it towards the future as a cloud and platform provider.
Frank von Orlikowski: “Mario Dönnebrink brings a wealth of experience in marketing, organisational development, building indirect partner sales and scaling business models to Portal Systems AG. In addition, as an external consultant, he will provide us with strategic and operational support in the implementation of these topics. We are very pleased to have been able to win such an expert for our company”.
Farewell after a successful five-year term
Michael Hoseas and André Grüneboom retired from the Board. The shareholders, the Management Board and the Supervisory Board thanked both for their commitment and expertise during their five-year term of office.
Following the successful transformation of Portal Systems AG into a provider of SaaS products, the company is now focusing on the strategic development and sustainable expansion of its business.
