FRITZ!Box router

The FRITZ!Box is a widely recognized brand of DSL, cable, and fiber-optic routers and networking hardware produced by AVM. Founded in 1986 in Berlin, AVM has grown to become the market leader in Germany for broadband terminal equipment. The brand is known for its distinctive red and white design and integrated software system, FRITZ!OS.

While AVM performs the majority of its research, development, and high-tech assembly at its headquarters in Berlin, Germany, the brand also utilizes manufacturing partnerships in countries like Poland and Vietnam for various components and models. Historically a privately-held German company, AVM announced in 2024 that the European investment firm Imker Capital Partners would become its new majority owner to ensure the company's long-term growth and succession planning.
