Gislaine De Abreu Macek
International commodities strategist, structuring discreet, high-value transactions across energy, agricultural, and metals markets.
Before the Credentials
A note, in my own voice
Working across three distinct industries has shaped a perspective on international negotiation that is both rare and deeply practical. I spent fifteen years evaluating contracts for international sports transfers, twenty years importing luxury furniture and negotiating directly with established global brands, and another twenty years as a publisher of international lifestyle magazines. Today, that experience converges in commodities.
None of it was planned as preparation for this work, but that is what it became. Years in sport meant negotiating with a lot at stake and an audience watching. Luxury taught me discretion, and that the relationships worth having are built slowly, not closed in an afternoon. Publishing trained my ear for what people leave out. Grain, oil, metal, the cargo changes, the people on either side of the table do not.
I founded GDK Investment Group not from a traditional commodities background, but from a foundation built on decades of international negotiation, cross-continental relationships, multilingual fluency, and a nuanced understanding of how trust is established across cultures. Transactions are not defined by price alone. They are defined by documentation, compliance, and the credibility of the parties involved. Underpinning all of it is trust, not declared, but demonstrated over time through consistency and conduct.
This professional introduction is a reflection of who I am.
