90 Years of Brosa

Dear Employees, Valued Customers, Honored Guests,
Today, we celebrate 90 years of Brosa – an impressive milestone that fills us with gratitude and pride.

Founded in 1935 in Berlin, we are now a medium-sized family business that has been deeply rooted in the region for nearly 75 years while also growing globally. Our success is based on the solid pillars that have accompanied us for decades: the close connection to our customers, the tireless dedication of our employees, and the ability to reinvent ourselves time and again.

Such an anniversary is no coincidence; it is the result of a collective effort. Our employees are the heart of Brosa – they not only bring their professional expertise but also their passion and spirit of innovation. Their commitment has repeatedly helped us to develop new solutions and strengthen our position in the industry. For this, we would like to sincerely thank all of you.

Equally important are our customers, who have placed their trust in us and accompanied us on our journey. Together with you, we have been able to implement demanding projects and drive forward innovative technologies that have an impact far beyond our region.

Brosa stands for progress through tradition. As a company anchored in the region, we bear responsibility – towards our employees, the environment, and the economic development of our local community. At the same time, we look ahead: innovation remains our driving force. We want to continue exploring new paths to create future-proof solutions for our customers and successfully meet the challenges of the coming decades.

Our 90th anniversary is not only an occasion to celebrate but also a promise: We will continue to act with passion and foresight to carry forward the success story of Brosa together with you.
Thank you for being part of this journey!
With our very best regards,



– Martin Wagner, Managing Partner, and

Markus Weber, Michael Dischl, and Elmar Schupp, Management.

Dear Sir or Madam,

Did you know that only about two percent of German companies celebrate their 100th anniversary? BROSA GmbH has already mastered 90 percent of this extremely challenging milestone and is well on its way to joining that elite group in the near future. Considering the numerous challenges the company has successfully overcome in the past and present—and, I am confident, will continue to master in the future—this achievement commands great respect. As a medium-sized, family-owned business, you can look back on a true success story that continues to unfold to this day.

From the relocation of operations to Tettnang on Lake Constance, to company acquisitions, demolition and reconstruction of buildings, and the establishment of branches in China, the Netherlands, and Singapore, to changes in corporate structure—a great deal has happened at BROSA over the past decades. The balance between regional roots and global growth has been a success—thanks to the commitment and passion of your employees, forward-looking leadership, professional expertise, a spirit of innovation, and a loyal customer base—truly a collective achievement.

From its founding as an independent business to becoming a corporate group with over 100 employees, BROSA GmbH has consistently stood for reliability, quality, and sustainable development. Your products are valued by customers in sectors such as mechanical engineering, the construction industry, and many other areas of application. With dedication and innovative spirit, the entire BROSA team makes a significant contribution to the future viability of Baden-Württemberg’s economy, as innovation is a key driver of progress, competitiveness across industries, and the foundation of our current prosperity.

I would therefore like to extend my sincere congratulations on your 90th anniversary and wish you all the best and continued success in the years ahead.

Yours sincerely,

Dr. Nicole Hoffmeister-Kraut, MdL
