About us
Two friends, one passion for technology
IT-Discount24 is not a faceless online shop, but a real computer workshop in Wiesbaden. Behind us are two people who love technology – and value quality and honesty.
Our story
From an aquarium pump to an IT company
Stefan Preuss and Sven Großer have known each other for over 20 years – a friendship shaped early on by a passion for technology. Stefan's father ran a computer shop, so Stefan grew up surrounded by hardware, repairs and everyday IT.
For Sven, the first spark ignited in 1999; in 2011 he built his first custom PC himself – water-cooled, improvised with a simple aquarium pump. What began as an experiment became the foundation of a real craft.
In 2023, the two founded Kryptontec GmbH together in Wiesbaden, from which the IT-Discount24 brand emerged. The result of decades of experience, genuine passion and the ambition not just to serve customers – but to truly advise them.
