• ABOUT THE COMPANY

  • Ernströmgruppen is a Nordic privately owned industrial conglomerate developing, manufacturing and selling technically advanced products and services, primarily to B2B customers.

    Our business model allows the companies to operate with a great degree of autonomy and report to a company-specific board, which ensures the long-term development of the individual company.

    In our view, this decentralised organisation not only creates the flexibility needed in today's increasingly volatile market; it also attracts competent, business-driven people who want to make a difference.

    We call this business model “Collective Entrepreneurial Power”.
