Provide Direction & Support

Executive Board, Management, and Department Heads

Our current success is attributable to ISR employees and their trust in an experienced management team. Since 1993, the ISR 'cockpit' has been steered with profound technical expertise and keen intuition. The Executive Board, Management, and Department Heads adeptly oversee the well-being of the company, its employees, and its clients. They prudently assess risks while also courageously pursuing new objectives, ensuring resilience in times of crisis.

Below, our management team introduces themselves from both a professional and personal perspective.

Chairman of the Executive Board

André Vogt

André Vogt has been the Chairman of the Executive Board at ISR since 2022, having joined from CENIT AG. In his role as head of the CENIT-EIM Group, which comprises CENIT AG, ISR Information Products AG, and mip GmbH, he has been responsible for Enterprise Information Management in the D-A-CH region and the USA for 12 years. 

His passion for client projects and their solutions led him early into consulting, making a professional entry into an internationally operating management consultancy in 1999 almost inevitable. He remains dedicated to Information Management to this day. Cross-industry contacts, projects, and innovative ideas drive his work in Data & Analytics and Document Logistics.

Andre Vogt

Personally, the Bielefeld native is interested in everything that can be driven: motorcycles, e-bikes, classic cars, and sports cars accompany his excursions and travels. Currently, his son, who also has a passion for automobiles, shapes André's leisure activities. André currently lives in Hamburg, where he enjoys good food and wine. He utilizes the proximity to the sea for family outings – often with classic cars.
From a sporting perspective, André is a 'fair-weather golfer,' and he has observed one thing: golf teaches humility – even after many years.

Executive Board

Manfred Merßmann

After completing his computer science degree in Karlsruhe, Manfred moved to Münster and embarked on a career as a freelancer. Following several stints as a freelancer, he quickly turned the idea of starting his own company into reality. Manfred was convinced that the fields of digitalization and process automation held great promise for the future and wanted to further develop them. The technology from FileNet (now IBM) and related partnerships remain an integral part of the ISR portfolio to this day. Since the founding of ISR Information Products AG in 2000, Manfred has co-led the company with Bernd and is currently responsible for four of the five operational business units: Document Logistics, Data & Analytics, Application Management, and Buildsimple, as well as internal IT.

Manfred developed a passion for sports early on – first for athletics and then for basketball. His shared passion for basketball with Bernd has endured to this day and is reflected in their close collaboration and support for the Uni-Baskets in Münster. Today, Manfred's athletic pursuits focus on a white ball, which still offers considerable resistance during golf. Beyond sports, he enjoys good food and a suitable wine with friends.

Thorsten Stefanski

Thorsten heads the Analytics & Insights division and likes to quote the following: “Analytics is the function within a company that enables the right decisions to be made.” Before taking over the division, Thorsten—a business informatics student—worked as an ERP developer and a DMS & process consultant, among other roles. Thorsten has been with ISR since 1995 and currently works with clients as a project manager for analytics projects.

As a dog owner, Thorsten enjoys extensive daily walks or jogs. He is an avid cyclist, valuing the journey over the destination, and often makes spontaneous visits to friends. Additionally, Thorsten frequently meets friends for barbecues and plays tennis.

In his private life, Wilhelm resides with his family in Wesel, located in the picturesque Lower Rhine region. A passionate supporter, he frequently visits Borussia Park in Mönchengladbach to watch the 'Foals' play football. As a counterbalance to his desk-bound work, Wilhelm enjoys long walks with his dog. To truly clear his head, he takes to his motorcycle. Whether on mountain passes in the Dolomites, gravel roads in Albania, or sandy tracks in Morocco, he relishes nature and explores different countries and cultures.

Head of Business Unit

Mark Hommola

A native of Hamburg, Mark has been a key member of the ISR Information Products AG team since 2011—since 2016, he has been in charge of the Document Logistics division, which he has co-led with Stefan as part of a strong dual leadership team since 2022. His career includes several positions at renowned consulting firms, including Siemens AG. His areas of expertise are project, process, and change management, which also bear his signature at ISR. He is passionate about the many exciting client projects and the challenges that digital transformation holds for us in the coming years.
Braunschweig has now become his home base. Mark has lived in the “City of Lions” with his family for many years.

In his private life, the word “outdoors” best describes Mark's interests, which, in addition to sports like running, cycling, and swimming, always include nature. A treadmill or an indoor pool are not for him; he prefers marathons through mountains and valleys, and a pristine lake or the sea for swimming.
This 'Nordlicht' (Northerner) repeatedly seeks the tranquility and vastness of Norway for extensive outback trips under the motto “the less, the better.” It's a welcome change from the otherwise digital and hectic daily routine. So, backpack on and off he goes…

Whether as a member of steering committees, a project manager, a post-merger integration manager, or a coach—he knows how to motivate teams and set projects on the path to success.

Stefan lives with his family in Essen and prefers to start his day with a walk in the park or by the lake, accompanied by the family dog. On Sundays, he runs with his running group at Lake Baldeney, staying fit for the relay marathon in Münster with his ISR colleagues, a sporting highlight he wouldn't want to miss. Away from the running track, Stefan enjoys time with his family, whether on excursions, listening to music, or simply outdoors in nature – the perfect balance to his digital professional life.
