Our Team

AIS combines 40+ years of experience mostly acquired during our tenure with world leading Private Equity and Sovereign Investment Houses. Over the years we have gained a strong expertise and deep knowledge of international investment structures with operations in Luxembourg. We have supervised financial, tax, accounting and legal aspects of more than 200 transactions (i.e. acquisitions, disposals, restructurings) and have organized efficient finance functions aligned with the global organisation and strategy of the business. This was done through hybrid models combining internal teams with outsourced workforces across Europe.
