THE COMPANY
Founded in Bordeaux over 30 years ago by Marc de Tapol, TDM Ingénierie specialises in the design and production of embedded electronic computers for military environments. Renowned for its expertise in signal and video processing, the company contributes to critical programmes for major contractors such as Dassault Aviation and MBDA. Following an industrial repositioning between 2016 and 2018, TDM evolved from an engineering consultancy to a product-driven business. This transformation, supported by strong market momentum, enabled the company to return to a path of profitable growth.
THE TRANSACTION
Ama Partners advised Marc de Tapol on the sale of TDM Ingénierie to the Serma Group, a leading French industrial player in embedded electronics and critical information systems. This transfer enables Serma to strengthen its position in defence-grade embedded systems and to integrate a highly differentiated expertise in AI-based image processing. For TDM, the deal provides a solid industrial platform for continued growth and for deploying its technology in large-scale projects. Ama Partners acted at every stage of the process: strategic planning, identification of potential acquirers, negotiation, structuring and coordination through to closing.

Ama Partners is proud to have advised on this strategic transaction, helping to secure and enhance a widely recognised French industrial know-how.

TESTIMONY
"Thanks to Ama Partners' support, I was able to approach this transition with clarity. Joining the Serma Group means safeguarding our know-how while integrating into an ambitious industrial dynamic. We share the same culture of excellence and innovation. Together, we are entering a new phase in the development of critical embedded technologies serving French sovereignty. Serma, as a mid-cap company (1,400 employees), will help break through the glass ceiling that often limits the growth of SMEs."
