At a time when demand for advanced security solutions is increasing rapidly, Stålpartier i norr and Keep the company are strengthening their joint management team. Magnus Brevemark is appointed Deputy CEO of both companies, as well as Chief Operating Officer of Stålpartier i norr.

The patented security solution is developed and marketed by Keep the company AB and has been created through close collaboration between the two companies, based on the high requirements of security-critical projects.
In light of a changing global situation and a sharply increasing demand for certified security solutions, the companies are now entering the next phase of their development, with the ambition of taking a leading position in the international market.
“As we continue to grow, our market and our projects are becoming more complex. To support this development, we need to strengthen our organizations with the right capabilities. Magnus brings a unique combination of operational experience, strong leadership and deep insight into security-critical environments,” says Ulf Isaksson, CEO of the companies.

“I see SPINAB and Keep the company as two companies with great potential, which have already come a long way and are now at a stage where the next step is crucial for their continued development.
