Our name and logo

Kalele is the Hawaiian language word for messaging. Messaging is at the center of everything that we do. Human language is a form of messaging between people. Language-based modeling is the key to using Domain-Driven Design. Exchanging messages between objects is the way that object-oriented programming was first conceived, and facilitates the best means to make software models explicit with modern hardware architecture that features many CPU cores.
Our logo design further emphasizes messaging. Forming a K for Kalele are two arrows that represent incoming and outgoing messages. Kalele is message-driven at our core.
