Greentree Investment Company

The co-founders operate across time zones by maintaining executive roles on both continents. Dr. Ola Brown travels frequently between Nigeria and the US, while Abasiama Idaresit runs Wild Fusion, a digital marketing firm with offices in Lagos, Accra, and Nairobi. The network effect from YPO Lagos and the World Economic Forum Young Global Leaders program gives Greentree access to founders that would be difficult to replicate from a purely US-based office.

Dr. Brown founded Flying Doctors Healthcare Investment Group alongside her work at Greentree. The two entities share a capital pipeline: Greentree has channeled investment into health-infrastructure assets, including an air-ambulance fleet, that sit under the Flying Doctors umbrella. The degree of legal separation between the two is not publicly detailed, but operational personnel overlap is clear from public record.

Greentree's capital structure is not publicly disclosed. The involvement of late Chairman Olabode Agusto — whose family controls Nigeria's premier credit-rating agency — suggests multi-family capital rather than a single patriarch's wealth. The firm does not market itself to institutional limited partners, which implies a partnership balance sheet or a tight group of co-investing families.

Greentree does not publish an exclusion list, but its observable portfolio — enterprise software, fintech, digital health, media — omits heavy infrastructure, extractive industries, and real estate development. The firm's intellectual roots are in services and technology adoption, not physical asset deployment. This pattern mirrors the co-founders' own operating backgrounds in healthcare, marketing technology, and credit analysis.

Olabode Agusto's passing removes a board-level figure who brought institutional credit analysis to Greentree's underwriting. Agusto & Co., the rating agency he founded, sets the standard for corporate credit assessment in Nigeria. The firm has not publicly named a successor Chairman, and it is unclear whether the Agusto family remains invested. This succession question is the single largest governance variable an external partner would want to diligence.
