The success of Intercom can be deeply intertwined with the technology they use in their stack. Eight years ago, Ember was released and has been used by Intercom for about six years, starting when the author joined the company. In that time, Intercom grew from a small office to 600 people across five offices, valued at over $1 billion. The web has undergone significant changes, with frameworks improving capabilities for small teams to produce amazing experiences in short periods. JavaScript has also evolved, and compilers like TypeScript and Babel have enabled experimentation and adoption of potential features earlier. Ember's strong conventions help new engineers get up to speed quickly, enabling Intercom to ship a feature on their first day and another the next week. The company uses a "ship every day" approach, with frequent releases following a six-week cycle. This allows for continuous improvement and adaptation to changing requirements. Ember follows SemVer strictly, ensuring backward compatibility, and has evolved its rendering engine from primitive to what is considered one of the best-in-class. Glimmer, introduced in 2.10, treats templates as a programming language, using a VM to run compiled code, resulting in fast parsing and compact size. The company's new set of modern Ember features, Octane, will land incrementally over the next six weeks, improving performance and capabilities.
