Joining MODULA 26
ESI began with the founding of RIDI multimedia GmbH in 1998 by Claus Riethmüller.
Claus began his career as a designer of innovative audio software solutions, where he was able to idyllically combine his interest in music and sound design with his skills as a software developer.
His company started with the distribution of select professional hardware and software in the music market.
The name ESI originated from audio products company Ego Systems, Inc. in Korea.
In 2006 ESI Audiotechnik GmbH was setup by RIDI to improve already existing ESI products and to offer unique new audio solutions with some truly innovative ideas. By 2010, all designs were carried out by the new ESI Audiotechnik GmbH in Germany.
In 2013 RIDI multimedia GmbH and ESI Audiotechnik GmbH were finally merged into one company.
Today, the product development is performed at the company headquarters in Leonberg, Germany.
