Deca is a cooperative of magazine writers co-owned and managed by its members. Their cooperative model is based on photo agencies like Magnum and NOOR. Each journalist reports and writes independently but stories are edited and promoted collectively. Their writers are based all over the world, including Rome, London, Shanghai, Barcelona, Beirut, Abu Dhabi, Los Angeles, New York, Seattle, and Washington, D.C. Collectively, they have reported from more than 90 countries and every continent but Antarctica. Deca's tagline is "The world, firsthand." They offer a subscription service to their stories as well as an iOS app, with an Android app in development. Readers can also purchase the stories for download as Kindle singles on Amazon.com.
