Established in 2000, Kelello has 25 years of experience in managing education projects across Africa. We welcome work with entities from a variety of sectors that share the mission of improving learning outcomes in low-income communities. These include corporations, universities, government departments, fellow education specialists, global NPOs and other investors. For most of our history we have operated as a mission-driven small business. We still operate as Kelello Consulting, though recently we also created a non-profit arm called Kelello Collectives. This includes board-oversight to cater for those situations where the entity structure better suits the need of our clients, usually multi-year large scale NPO-funded capability or content-creation programs. Regardless of how we partner, if your goal is to improve education outcomes, we would like to explore the opportunity of working together.
