Our
Leadership

Kofi Owusu-Acheaw, Chief Executive and Managing Director of Semper, KOACH & O.

Kofi Owusu-Acheaw

CEO & MD

Kofi Owusu-Acheaw is the Chief Executive and Managing Director of Semper, KOACH & O. Ltd (KOACH & O), the strategy and advisory firm he founded on disciplined thinking, institutional navigation, and long-term value creation. A pan-African industrialist and economist whose foundation combines Economics and International Business Strategy, he has shaped the firm's philosophy: lead with clarity, move with integrity, and align the right people, structures, and timing to unlock outcomes.

A highly experienced change leader, he has a proven record of delivering complex projects across diverse industries in Africa, the United States, and the UAE, with depth across the full value chain of the extractives, finance, energy, infrastructure, security, and development-management sectors, and particular strength in assurance and advisory. Beyond the firm, he builds the capability Africa has too often had to import, having founded ventures in artificial intelligence and autonomous systems on African soil, led a workforce of more than 1,300, coordinated a billion-dollar smart-city programme, and built enterprises spanning private credit, trade, and food security.

Known for a measured, principled approach, Kofi advises across real-economy sectors including agribusiness, logistics and infrastructure, strategic real estate, financial services, and security-focused technology. His conviction is simple: that Africa should produce, not import, the capability that secures its own future.
