21 Grams - gruppen

About us

KC DATA was started in 1990 by Kaj Christensen, and is now a part of 21grams. Currently 21grams delivers the most cost-effective and reliable address processing system in the Nordic region.

The story of PostSort begins in 1990, when Kaj Christensen was contacted by Sjöbergs Bokbinderi, a bookbinder in Stockholm, who needed problems solved with regard to sorting addressed products. At the time, sorting was done manually, which caused quality problems and a low speed of production. Stricter requirements from the Swedish Postal Service made conditions untenable. That was the starting point for KC DATA, which today is the leading supplier of addressing systems in the Nordic region.
