Room Key competes in the crowded, conservative hospitality market. Its CTO Colin Steele chose Clojure before we even spoke to him, and you can read his original account of that decision. Clojure was the right combination of performance and simplicity – accelerating the team’s efforts and codebase. Room Key partnered with Cognitect for support and expertise in Clojure, and we embedded developers, designers and project managers with its team to deliver on its road map. Later, Room Key adopted Datomic to leverage DynamoDB more effectively, since its team built the system natively on AWS.
