Institutional Stewardship for High-Growth African Markets.

Who We Are

Patient Capital for Africa’s Real Economy

AST-AAR Capital Investment is a UK-based investment holding and sponsor platform focused on long-term value creation across Africa’s essential real-economy sectors. We deploy patient, well-structured capital into agribusiness, sustainable land use, energy & power, logistics, and productive infrastructure—backing platforms with strong fundamentals and clear pathways to scale.

As long-term stewards of capital, we partner closely with founders, operators, and communities, combining strong governance, disciplined capital allocation, and rigorous ESG oversight. AgriFrontier Platform Limited, our Sierra Leone–registered operating company trading as the Senehun Agri Platform, anchors our agribusiness strategy—supporting management teams through growth and transition while measuring success by durable cash flows, institutional quality, and sustained intergenerational value.

Who We Are
Our Story

Built for Resilience

AST-AAR Capital Investment was formed to address one of Africa’s most pressing challenges: the need for scalable, well-governed, and resilient real-asset platforms across agribusiness, energy & power, logistics, land, and property. Recognising the continent’s long-term growth potential, we were founded to act as a patient, long-term sponsor—bringing structure, discipline, and capital alignment to operating businesses across Africa.

Our role is to partner with entrepreneurs and operating teams, strengthening foundations, supporting responsible growth, and building platforms designed to endure, scale, and deliver lasting economic and social value.
