İstanbul / İzmir, Türkiye — Delta3, the B2B sports technology company behind the FanOS fan identity and engagement platform, today announced a partnership with Göztepe SK, one of Türkiye's most historic clubs, to build and operate the club's digital fan platform.
Founded in 1925 and based in İzmir, Göztepe SK commands one of the most loyal fanbases in Turkish football across a metropolitan region of nearly five million people. The club finished 6th in the 2025–26 Süper Lig.
Under the partnership, Delta3 will deliver a white-label fan app giving Göztepe direct ownership of its supporter relationships, embedded membership, and engagement infrastructure that runs on a proprietary operating system, FanOS. The program is designed to let Göztepe create a platform to establish meaningful relationships with fans digitally and own and monetise its fan relationship directly rather than cede it to third-party platforms.
