Oklahoma City-based startup BitConfused created Cage to make it easier for creatives to share and approve creative work. Now in public beta, the app aims to provide a secure environment for creative teams to easily upload and present files, manage tasks, organize revisions and receive approvals. Since Cage entered private beta last year, more than 20,000 creatives have signed up to use the product. The public beta version includes several new and improved features including allowing users to receive client approval directly within the app.
