OneGro is a Southern African commodity trading company specialising in the sourcing, trading, and movement of agricultural commodities and selected mineral products. We operate across regional and cross-border markets, supporting producers, processors, and industrial buyers with dependable, market-driven supply solutions.
Our role extends beyond transactional trade.

This integrated approach enables our partners to operate with greater certainty in complex and often volatile market environments.
With a growing footprint across Southern Africa, OneGro continues to expand its commodity offering with the objective of becoming a trusted, single-source trading partner for customers across agricultural and industrial sectors.

We are driven by a culture of professionalism, accountability, and innovation. Our team challenges conventional approaches to commodity trade and continuously seeks more efficient, sustainable ways to move products from source to market.
At the core of our operations is a commitment to honest and transparent trade, ensuring balanced value for both suppliers and customers. This philosophy supports the development of resilient, long-term supply chains — from mine to metal and from farm to family.
Integrated Trading & Logistics Capability
OneGro’s competitive advantage lies in the integration of commodity trading expertise with deep logistics capability. Our leadership’s background in large-scale transport and cross-border logistics provides a practical understanding of the physical movement of goods across Southern Africa.
This insight allows us to anticipate operational challenges, manage delivery risk, and ensure continuity of supply. By combining commercial insight with operational discipline, OneGro delivers consistent, reliable outcomes across diverse markets and industries.
