The firm
A transatlantic perspective grounded in execution.
Muller Advisory Group is a selective, human-led global B2B sourcing portal. Established in New York in 2020, MAG turns buyer mandates into field research and qualifies products against target-market realities.
MAG acts as curator and gatekeeper between buyers, brands and producers. Technology supports the analysis; selection and introductions remain MAG decisions.

Founder
Sébastien Muller
Sébastien Muller brings over a decade of operating experience in New York and a transatlantic perspective between France and the United States. MAG applies that practical lens to market entry, commercial development and local execution.
That experience informs a practical understanding of suppliers, operations, local commercial expectations and the work required between European ambition and credible North American execution.
