Warner Bros Discovery

“Having worked closely with Florian and Michael through the German-American Executive Roundtable (Deutsch-Amerikanische Wirtschaftsrunde), I’ve come to value their rare ability to combine strategic foresight with operational depth. They bring a clear understanding of the financial, regulatory, and cultural dynamics that European companies face when entering the U.S. market.Their advice is never theoretical – it’s grounded in experience, pragmatism, and a real commitment to helping companies succeed on both sides of the Atlantic.”

Tengelmann Group

“Many German Mittelstands companies face a dilemma when expanding into the U.S.: they need expert guidance, but often find it difficult to identify a partner who offers both strategic insight and the personal, custom-tailored support they’re looking for. That’s where AtlanticNexus stands out. Florian and Michael offer deep U.S. market expertise, hands-on execution, and the kind of senior-level attention that Mittelstand leaders value. I’ve known both for many years – professionally and personally – and I’ve seen how effectively they guide companies through the complexities of market entry while staying true to each client’s unique culture and goals. For owner-led and family-owned businesses, their partnership offers exactly the right blend of trust, experience, and strategic focus needed to successfully enter the U.S. market.”

I’ve known them both personally and professionally for many years, and I can say with confidence that AtlanticNexus is exceptionally well-positioned to help European companies navigate the U.S. market at a time of real complexity and opportunity.”
