Weinberg Capital Partners

Company overview

Founded in 1965, Chesneau-Serret has established itself as a leading player in high-precision mechanics in France. The group designs and manufactures critical, complex-geometry components for demanding sectors such as civil and military aerospace, as well as the medical industry.

More specifically, the group offers its clients comprehensive services (machining, fitting, radiusing, 3D measurement, honing, bench testing, balancing, assembly) along with engineering capabilities (including development and technical support for special-purpose machines, for example).

Our approach

The entry of the Eiréné #1 fund, which specializes in supporting SMEs and mid-sized enterprises (ETIs) in the security and defense sectors, marks a significant milestone for Chesneau-Serret’s growth. This partnership will support the group’s ambitions by consolidating its presence in its traditional markets, accelerating its expansion into new segments, and pursuing an ambitious external growth strategy.

Thus, less than a year after Eiréné joined its shareholding structure, the group acquired LGB, a specialist in machining complex parts.

This combination is built on strong technical and commercial complementarities between the two companies. It will enable Chesneau-Serret to broaden its customer portfolio and service offering while increasing its production capacity.
