Twelve South develops premium accessories exclusively for Apple devices — stands and docks (HiRise, BookArc), charging solutions, and the signature BookBook cases for iPhone, iPad, Mac, and Watch. The brand, based in Charleston, South Carolina (founded in 2009), is closer to the Apple look than almost any other.

​

The Apple connection is maximum: Twelve South is "Apple only" and is demonstrably sold directly through Apple (apple.com and Apple Retail Stores) — a strong selling point at the point of sale. The core target group is Apple end customers (B2C); via wholesale, the brand is also relevant for B2B partners.
