Jul 15, 2025

Activa announces its investment in Desegur Group, a specialist in TICC (Testing, Inspection, Certification and Compliance) services for the healthcare and nuclear sectors. Through this transaction, Activa becomes the reference shareholder alongside the two founding executives.

Founded in 2005 by Céline Dott and Alexandre Filali, Desegur provides certification, inspection and compliance services to more than 8,000 clients across France, with deep expertise in radiation protection for the nuclear, industrial and medical sectors. The group is recognised as a trusted player in the TICC market, notably holding 3 COFRAC accreditations and several certifications that have been renewed for over 12 years. Supported by an experienced and committed team of 60 employees, Desegur currently generates more than €11 million in revenue. The company stands out for its agility and responsiveness, reinforced by a high level of process digitalisation.

Backed by Activa, the group intends to accelerate the external growth strategy initiated in 2024 with the acquisitions of Bureau de la PCR and DSG IT, specialists in radiation protection for the medical sector, while continuing the organic development of its service offering.

Activa, which specializes in supporting French SMEs in the technology services sector through primary transactions, announces with this investment the 8th transaction of its latest vehicle, Activa Buy-Out Fund II. Activa will bring its expertise to support and structure Desegur Group’s growth trajectory.

Celda Capital Développement, which supports regional companies in their development, transmission or capital reorganisation, is participating as co-investor in the transaction.

Céline Dott and Alexandre Filali, Founders and Managing Directors of Desegur Group, declared:
“We are convinced that Activa is the right partner to support the deployment of our growth strategy, both organically and externally. Their experience and know-how in structuring and executing external growth operations are a real accelerator, already enabling us to bring some of our development ambitions to life.”

Christophe Parier and Alexandre Masson, Managing Partners at Activa, added:
“We are proud to support Céline Dott and Alexandre Filali in the continuation of their ambitious development strategy. Desegur is a recognised reference player in its sector, and we are confident that it has the right assets to play a key role in the consolidation of the French TICC market.”
