Together we are strong. You've come to the right place!
In our view, a group of established companies will achieve disproportionate growth and success in the currently highly fragmented electrical engineering market. The group's companies will benefit disproportionately from joint activities and synergies – together, we can better overcome challenges such as recruitment, digitalization, and increasing complexity. Furthermore, we can consolidate purchasing and commercial activities, share best practices, and improve together. For this reason, we are building a strong, agile, entrepreneurial network with leading companies in German-speaking countries.
We want to cover all trades in electrical engineering, such as telecommunications construction, energy technology and distribution, building technology, network and data technology, security technology, control technology, automation.
The group of companies is consolidated under the E.GROUP name in each country.
Are you looking for a succession solution or are you an ambitious entrepreneur?
For this joint project, we are specifically seeking other established companies in the electrical engineering sector whose owners (if desired) and management, together with us—an entrepreneurial and financially strong partner—want to lay the foundation for the next growth phase of their company. Together, we aim to further expand your company's significant market position in this strategically attractive market.
