Profile
The parent company was founded in 2016 by a private entrepreneur. This with the aim to build up and bundle a portfolio of successful medium-sized industrial companies in the wire processing industry and to use common synergies as strength.
In addition to the successful and organic growth of the existing group of companies, the focus is now also on targeted acquisitions and investments in innovative companies in attractive market niches.
As a medium-sized industrial group, the concentration is exclusively on medium-sized companies with the primary objective of increasing the enterprise value of the entire group on a sustainable basis.
The strength of the SIGEMA GROUP lies in the diversification of the investment portfolios, the significant financial strength of the parent company as well as in the strategy geared to long-term growth.
