Cross-border M&A and performance execution

ONIX Associates is an independent cross-border M&A advisory boutique supporting SMEs, multinationals and investment funds across France and the Benelux (Flanders, Wallonia, Brussels and The Netherlands).
We combine M&A execution with HR transformation and hands-on delivery—implemented locally to secure measurable performance improvement.

Mergers & Acquisitions

We advise shareholders, founders, management teams and investors on mid-market transactions, from preparation to negotiation and closing—especially in cross-border Benelux–France contexts.

Typical services:

  • Sell-side advisory (structured process, value maximisation, execution control)
  • Buy-side advisory (target search, deal thesis, valuation/terms support)
  • Post-deal integration & value capture (100-day plan, synergy tracking, governance)

HR Transformation

We help organisations strengthen structure, leadership and HR execution—so performance improvements actually stick. We intervene in transformation contexts: growth, integration, reorganisation, performance pressure or leadership renewal.

Typical topics:

  • HR diagnostic (audit) & operations (governance, HR process optimisation, HR data/KPIs)
  • Talent & key-role recruitment (search & selection, onboarding/90-day plan)
  • Transformation & performance improvement (company reorganisation, workforce reduction, footprint & site closure, performance improvement plan)
