Flowdock is a group chat and a business messenger acquired by RallySoftware. It was created with the idea of creating a centralized 'team inbox' but fell short of the goal since Flowdock never managed to integrate email server, project management, document management and other team tools. Flowdock creators also decided to concentrate on software developers as their target audience, failing to provide tools and integrations relevant to 'regular business'.
