Our Founder

Esther Annette Lumumba

Étoile was founded by Esther Annette Lumumba, whose decade of experience across energy and infrastructure on the research, production, and business development sides gave her a clear view of what African markets needed most: not more capital, but better connectivity between the right people.

"Africa does not have an opportunity problem. It has a connectivity problem. Étoile was built to solve exactly that, bringing the right people to the same table, at the right moment, with the right commercial intent."
