Courier, a company focused on making software-to-human communication delightful, experienced significant growth in 2021. The company grew its notification volume by 13X, which forced the team to mature quickly and rebuild their infrastructure with serverless technology to meet scale demands. Courier's customer growth was also impressive, with ARR growing 14X, largely driven by organic demand without a dedicated sales hire until Q4 of that year. To support this growth, the company prioritized investing in culture, adopting a hybrid-remote work environment and establishing core values such as talking to customers and having fun as a team. With plans to triple its team size this year, Courier is seeking talented engineers to join its mission.
