KRIWAN Holding

The KRIWAN Holding

After the death of company founder Friedrich Kriwan, the company assets were transferred to the Friedrich Kriwan Foundation. The foundation is dedicated to charitable tasks. KRIWAN Holding is responsible for asset management. The companies KRIWAN Industrie-Elektronik GmbH, KRIWAN Testzentrum GmbH, Birkholz Elektronische Geräte GmbH, as well as KRIWAN's foreign branches, are connected to KRIWAN Holding.

The Friedrich Kriwan Foundation

Founded by Friedrich Kriwan, the foundation takes precedence over KRIWAN Holding and the KRIWAN companies. As the driving force behind our commitment to creating excellent electronic solutions, we extend beyond the boundaries of entrepreneurial activities. The foundation was established to provide not only conceptual but also financial support for research, science, and education in the field of technology. This commitment extends not only to our own companies but to society as a whole. By promoting cultural life in Hohenlohe, we contribute to creating a vibrant and inspiring environment.
