This old saying fits the Jamaican culture of ‘Kumina’, whose members believe in the power of passing on the knowledge of their ancestors. Our company name reflects this philosophy and our strong belief in open source ideals.

Kumina has specialised in Linux and open source software ever since it was founded in 2007. We use the most amazing open source technologies to help organisations turn IT into business value. We also love to give back to the community. On this page, you can discover our open source projects and contributions.
