Clubhouse is a tool for engineering and product teams that provides a big picture view. It uses a stack of Clojure, JavaScript, Datomic, and other technologies. Clojure was chosen for its functional programming approach and support for concurrency. JavaScript allows for a flexible front end. Datomic is used for its fully transactional and distributed database capabilities. The overall goal is to reduce friction and allow teams to move faster through simple and thoughtful tools.
