Kaiko was a German development studio founded in autumn 1990 by Chris Hülsbeck, Frank Matzke and Peter Thierolf. The studio started as A.U.D.I.O.S (Art Under Design, Imaginations Of Sound) and Kaiko was created as a label for it until it became the main name.

By 1993 the company was deep in the red numbers. Kaiko reached out to Software 2000 for funding and support, but it was ultimately disbanded around 1995. It took Hülsbeck until 1999 before all debts were paid.

Kaiko re-appeared in 2015.
