In November 2021, SerNet, Inc. has been re-established with headquarter in the heart of San Francisco, after a first subsidiary in California already existed for a temporary customer project from 2008 to 2011.

SerNet Germany was founded in 1996 in Goettingen and registered in the city's commercial register in 1997.

In 2005 the location in Berlin was opened to ensure fast response times in a Linux project for the German Parliament.
