    In addition to management, board and 23 individuals forming an advisory network to the company, AB Max Sievert is owned by four investors: Ramsbury Invest AB (privately held by the Persson family and the principal shareholder in H&M), The Fourth Swedish National Pension Fund (AP4), IMAS Foundation (sister foundation to INGKA Foundation, owner of the INGKA Group, which in turn owns the majority of the IKEA department stores globally) and Pomonagruppen Invest AB (privately held by the Rapp family).

    These owners see long term focus and innovation as critical to sustainable profitable growth.

    The long term ownership approach is assured through a shareholders agreement for the company.

  • Team

    The AB Max Sievert team is in place and consists of four full time employees, a board as well as a group of involved co-owners who participate in active ownership of the portfolio companies.

  • History


    AB Max Sievert restarted in 2014 and its business is to a large extent based on the values on which the family business AB Max Sievert, founded in 1882, was built.


    Three brothers started three companies

    AB Max Sievert was originally founded in 1882 by its namesake, Max Sievert, the oldest of three brothers. He and his younger brothers, Georg and Ernst, moved from their hometown of Zittau in Saxony to Sweden and quickly became Swedish citizens. From Germany they had supplied the growing industrial sector in Sweden, Russia and other countries with German machinery and industrial supplies.

    In Sweden they founded three companies together that started, invested in and developed international businesses based in Sweden: the parent company, AB Max Sievert; Sieverts Kabelverk, and AB Alpha. The original headquarters was located at Brunkebergstorg 2, in Stockholm. An oil painting of the building is shown on the first page of this site. The address is now home to the Riksbank, Sweden’s central bank, in a new building.

    The common denominator for all three businesses was that they developed and supplied innovative, high-quality products for an international market. Early on the brothers formulated the values that would distinguish the culture: “Hard work – Sensible thrift – Open-mindedness – Steadfast honesty.”


    Four generations

    The business continued for nearly 100 years and three generations until the late 1970’s. Max was originally CEO. When he died in 1913, Ernst became head of Sieverts Kabelverk. Max’s son Rolf, who had no interest in business, became a nuclear physicist and lent his name to a unit of measurement for radiation, “sievert,” still used around the world today.

    Georg was CEO of AB Max Sievert in 1913 -1930, after which his son, Hans Georg, took over. When Hans Georg died in 1965, his son Björn took over. The biggest businesses were sold in 1928 and 1965; see below.

    No business was run under the AB Max Sievert name after 1978, until 2014, when it was revived by the fourth generation through Björn’s son Christian, together with several investors. See also Owners.

    Sieverts Kabelverk and LM Ericsson

    Sieverts Kabelverk was founded in 1888, initially as a supplier of German cable to the emerging telecom industry, including LM Ericsson and Telegrafverket. The Sievert brothers and Lars Magnus (LM) Ericsson formed a close partnership. Georg and LM later became related through marriage.

    A few years after its formation, Sieverts Kabelverk opened its own factory in Sundbyberg, just north of Stockholm. Sundbyberg developed as a city largely thanks to Sievert’s three factories there. Sieverts Kabelverk became one of Europe’s largest cable manufacturers and helped to electrify a large part of the Nordic market with its high-tension cables, not to mention the cables that built the telephony network. Around 1920 Sieverts Kabelverk accounted for a third of the LM Ericsson group’s purchases and LM Ericsson for a third of Sieverts Kabelverk’s sales.

    In 1928 LM Ericsson acquired Sieverts Kabelverk and ran it as an independent company under the same name for nearly 60 years until 1980’s, when LM Ericsson changed its name to Ericsson and Sieverts Kabelverk changed its to Ericsson Cables.


    AB Alpha – Introduced bakelite in the Nordic countries

    AB Alpha also opened a factory in Sundbyberg and manufactured various instruments for the telecom industry, including handsets in bakelite, the forerunner to plastics, which it introduced in the Nordic region. Prior to that, all phones had been made of wood. AB Alpha was acquired in 1928 by LM Ericsson as well.


    AB Max Sievert – Machinery dealer and Nobel oil

    AB Max Sievert owned and initially started a machinery dealership. In 1888 it introduced a thick catalog with various machines, instruments and supplies. Among other things, it brought mineral oil to Sweden in the 1880s as the exclusive agent for the Nobel Brothers’ oil from Baku.


    AB Max Sievert – Blow lamps, Butane stoves, Measurement instruments, Soap dispensers, Distilling apparatuses, Industrial furnaces, Industrial scales…

    In addition, the company became a world leader in the manufacture and sale of blow lamps, with its own factory in Sundbyberg. It also developed butane stoves for the consumer market. This part of the business was acquired by Esso in 1965. Soon thereafter Esso also acquired a competitor, Primus, from Bahco and merged the two into Primus-Sievert. Primus focused on the consumer market and Sievert primarily on industry. Both brands still thrive to this day, though under new and separate owners.

    To see the monograph from the 100th jubilee of Primus-Sievert in 1982, click here (pdf).

    AB Max Sievert also became a leader in industrial furnaces, with its own factory in Ulvsunda, as well as in processing controls, industrial weighing scales, distilling apparatuses and soap dispensers for hospitals, laboratories and public spaces.


    AB Max Sievert starts again, 132 Years after its founding

    AB Max Sievert had not been in business since the late 1970’s. In 2014, nearly 40 years later, Christian Sievert, through C Sievert Holding AB, and three investors started a new company with the name AB Max Sievert for the same purpose – to develop innovative, profitable businesses based in Sweden and the Nordic region.

    While the company and its owners are new, the business takes inspiration from, and builds on, the values that AB Max Sievert rested on for over 130 years. See also “About us”.

  • About us

    A group of companies with sound corporate cultures

    AB Max Sievert is a group of well run Swedish and Nordic companies. An active co-owner of companies that strive to be best in class and contribute to their long-term development.

    Development in our companies is achieved by ensuring the best customer offering through continuous innovation and improvements, a competitive cost structure and a willingness to grow organically and possibly through acquisitions. One essential to success is to establish and build on sound values and a strong corporate culture.

    To develop well over the business cycle, the financial risk in terms of debt should be limited and adapted to the sector and business plan. In this way our companies can grow aggressively whether the economy is growing or contracting.

    We are owners without a defined exit horizon. Our return is generated through long-term appreciation and dividends over time.


    With the company’s best in mind

    Since exits aren’t our goal, what guides us is what is best for the company’s long-term development.

    Delivering short-term results is a key to sustainable development. But if short- and long-term interests conflict, we always choose the latter.

    We are happy to provide capital for investments and acquisitions that create value. Dividends are taken only to the extent that the capital cannot generate a better return through investments in the business.


    Support and match management

    Together with the other owners, we work through a small, accomplished board of directors that serves as a sounding board for management. We are careful in delegating responsibilities between the owners, board and management and believe that everyone will thrive if all these groups are well informed.

    On the board are individuals whose experience can benefit the company. Directors and management are personally invested in the company in order to share the same view of opportunities and risks as other owners.


    Engaged owner

    We want to be an engaged owner with a thorough understanding of our companies’ businesses, customers, employees and markets. This is why we won’t spread ourselves too thin, instead focusing on a few holdings, all of which are important to us.

    The aim is to know just as much about the companies and their markets as an entrepreneur or family business can about theirs.



    Our commitment and the way we treat each other and others are based on four principal values: Drive, Simplicity, Innovation, Teamwork. They are the product of a long tradition at AB Max Sievert dating back over 130 years. See also “History”.



    AB Max Sievert complies with the UN’s Principles for Responsible Investments (PRI).
