#Eiréné - Security and defense

The Eiréné fund of Weinberg Capital Partners is taking a majority stake in the Semip-Codechamp group, the European leader in high-performance angular position sensors


The Eiréné fund, dedicated to supporting SMEs/mid-caps in the security and defense sector, is making its first investment in the Semip-Codechamp group to support its next growth stage. Eiréné is partnering with the group as the majority shareholder, alongside the management team who is reinvesting significantly in the operation.

Founded in 1959 and led by Serge Finkelstein, the Semip-Codechamp group is a key player in the field of high-performance angular position sensors, serving the most demanding markets such as defense, space, civilian nuclear, and motor racing. With innovation at the core of its strategy, the group has around sixty employees, a quarter of whom are involved in the design office and R&D.

The group’s development, targeting prestigious clients, has been built on an unique expertise, on innovation, and on its products known for their excellence and performance through Europe.

Weinberg Capital Partners’ investment in Semip-Codechamp will accelerate the development and structuring of the group and support its growth ambitions in its core markets as well as new markets (civilian and international), and initiate an external growth strategy.

The significant reinvestment of the management team alongside Weinberg Capital Partners is a proof of its strong belief in the group’s development potential.

This primary operation, the first for the Eiréné fund, is at the heart of Weinberg Capital Partners’ expertise: supporting and structuring a group to accelerate its development through organic and external growth.

The completion of the transaction, subject to the usual authorizations, is expected by the end of June.

“I am very pleased with the arrival of Weinberg Capital Partners, which appeared to us as the natural partner to help Semip-Codechamp structure itself and accelerate its development. The Eiréné fund team has demonstrated a deep understanding of our industry, true expertise in the defense sector, and a genuine capacity for support. We are delighted to partner with them for this new phase for the group.”
Serge Finkelstein – President of the group Semip-Codechamp
“The investment in Semip-Codechamp is the first one of our Eiréné fund dedicated to the security and defense sector. This primary operation is perfectly consistent with our strategy to invest in French SMEs/mid-caps with a recognized leadership position and technological expertise in the defense market. We are delighted to be able to support the entire management team of Semip-Codechamp in this new important phase for the group.”
Lionel Mestre – Partner and Managing Director of the Eiréné expertise at Weinberg Capital Partners
