RYDGE Conseil makes first international move with Luxembourg acquisition

What's the deal? RYDGE ConseilDealroom has a profile for this one. Try Dealroom →, a major French accounting and advisory firm, has acquired CabexcoDealroom has a profile for this one. Try Dealroom →, a Luxembourg-based accounting firm founded in 2008. Cabexco has 31 employees, two partners, 650 clients, and three offices across Luxembourg — in Windhof, Belvaux, and Nothum. It handles around 2,700 payslips and offers services in accounting, tax, payroll, and legal advisory.

This is RYDGE Conseil's first acquisition outside France. The firm claims 200 locations, 4,500 employees, and 100,000 clients domestically.

Cabexco's existing team and management will stay on, preserving continuity for clients.

Why now? The two firms have collaborated for over a decade, making this a natural next step rather than a cold deal. RYDGE Conseil's co-founders Olivier Balestraci and Julie Ravard called Luxembourg "a strategic market at the heart of cross-border economic dynamics."

For a firm born from Fiduciaire de France and KPMG's legacy, expanding into Luxembourg — a hub for cross-border finance and corporate services — aligns with growing client demand for multi-jurisdictional support.

What could go wrong? Luxembourg's accounting market is small but competitive, with established local players and Big Four firms all present. Integrating a 31-person team into a 4,500-strong French network without disrupting client relationships will be the key test.

Cross-border regulatory differences between France and Luxembourg could also add complexity to service delivery, even for neighbouring countries within the EU.

The signal: RYDGE Conseil, classified as an "early growth" firm on Dealroom despite its 4,500-strong workforce and KPMG heritage, illustrates how mid-market professional services consolidators in Europe are still in the early innings of cross-border expansion. The acquisition of Cabexco — itself also at an early growth stage — suggests that Luxembourg's dense ecosystem of holding companies and fund structures remains an attractive entry point for French advisory firms looking to build multi-jurisdictional scale through bolt-on M&A rather than organic buildout.
