The Karström Group was founded in Haverö in northern Sweden at the end of the 19th century. The twelve Karström brothers were responsible for the security and power production of the Haverö Strömmar river. The name Karström translates to "men who work with electricity".

• In the middle of the 19th century, the state took over the monopoly business of electricity generation in Sweden and Haverö Strömmar closed in 1944.
• The second generation of Birger Karström began with the built-up telephone exchange in Sweden. This lasted until 1990 when the analog business transitioned to digital, which was set up by the state.
• Birger Karström in the second generation and Christer Karström in the third generation restructured the company with security systems.
• In the 21st century, Christer and Patrick Karström (fourth generation) are building the companies as one of the leading firms for knowledge-building solution systems in Sweden.
• In 2021, the business is expanded in Europe with a Swiss office to cover the European market with the same services.
• Today, Karström is globally engaged.
