The Team

Real people. Real service.

No corporation. No call centre. You always speak directly with the expert.

Since 1999, Stefano and Sabine Rost have run their computer service business in the heart of the Isartal near Geretsried — surrounded by Bavarian nature, the Alps in view and the River Isar at the doorstep.

What began as a passion for Apple devices is today a full-service IT business for private clients and SMBs. Personal, reliable, transparent — just as you'd expect in a region where people still know each other.
