What Siewert & Kau does

The company distributes classic IT hardware, technology products, and accessories, complemented by customized solutions, an e-commerce online shop, and a Supplier Partnership Program for onboarding new vendors.

The business generates revenue primarily through hardware sales and value-added distribution services, including RMA and after-sales warranty processing, dropshipment logistics, and EDI connectivity. GTM is sales-led, with a direct sales team reachable via [email protected] for project quotes and personalized consultation, supplemented by an e-commerce online shop at siewert-kau.com.

The restructured entity retained over 110 jobs, with co-founders Oliver Kau and Björn Siewert continuing as Managing Directors. The company reports operational scale of over 15.7 million items dispatched annually through a broad shipping partner network including DHL, DACHSER, DSV, FedEx, Rhenus, Schenker, trans-o-flex, and UPS.
