DKay.com was formed Jürgen Engler after the initial split of Die Krupps in 1997. He recorded the album 'Decaydenz' with a variety of guest musicians, including Julian Beeston (ex‑Nitzer Ebb) on two tracks, as well as Adam Grossman (from Skrew), Chris Van Helsing, Birgitte Fischer and Doro Pesch. This album was released in 2000.

A second album 'Deeper Into The Heart of Dysfunction' followed two years later. The project toured as support to Gary Numan and also went on a European tour with Genitorturers and Last Rites. When on tour, Jürgen Engler was accompanied by Specta (keyboards), Marcella Degaz (guitar) and Mike Zero (bass). The project has effectively been dormant since the reformation of Die Krupps in 2005.
