About Freeside Internet Services, Inc. and the Freeside project

Freeside had its start as an internal application for a large regional ISP in 1996. In 1998, after obtaining copyright to the code from his former employer, Ivan Kohler released the first open-source version of the code. Growing demand for commercial support and services prompted him to start providing Freeside consulting full-time in 2001.

Freeside Internet Services, Inc. was incorporated in 2005. Focused initially on development, offerings expanded to support, services and hardware.

The company provides consulting services, pre-configured hardware, support, customization and training for the Freeside billing system and other aspects of ISP and network operations. Freeside Internet Services, Inc. is a privately held California corporation.
