09/18/2025

Weinberg Capital Partners acquires a stake in Albaron, a leading player in quality assessment and auditing, in order to support its CEO in building a multi-expertise platform in the Testing, Inspection, Certification and Compliance (TICC) sector.

The Albaron Group, currently operates through three brands : 4 As, Sunnikan Consuting, and Calix. Taken over in 2019 by Charles-Antoine de Fontenay, its current CEO, 4 As has etablished itsel as a specialist in QSE certifications, external quality assessments of social and medico-social establishments and services, as well as quality control of training organizations and Qualiopi certification.

Eager to expand its expertise in a context of growing regulatory requirements in France and Europe, Charles-Antoine de Fontenay broadened the group’s scope in 2023 with the acquisition of Sunnikan Consulting, a recognized player in quality management for clinical research and pharmacovigilance.

Weinberg Capital Partners’ investment now enables the continuation of this external growth strategy with the integration of Calix, a QSE consulting firm also active in human resources services. This transaction reflects a shared ambition to consolidate the market and build a leading platform for consulting and assessment in the fields of healthcare and sustainability, serving Albaron’s clients.

For Weinberg Capital Partners, this marks the fifth investment of the LBO WCP #4 fund, following Arbevel (now Montpensier-Arbevel), Groupe ProNet, Cosmogen, and Summa.

“We have been following Albaron since its takeover by Charles-Antoine de Fontenay and are impressed by the group’s progress. We are delighted to support it in a new phase of growth, focused on issues related to sustainable development.”

Dimitri Fotopoulos – Partner at Weinberg Capital Partners

“We were convinced by the LBO team’s highly professional yet human approach, and we are very enthusiastic about entering this new phase of structuring and growth with the support of Weinberg Capital Partners.”
