Businesses based on open source software

Open source software is code that is released with a license that allows the public to view, use, modify, and distribute the software. Commercial open source software (COSS) companies are those whose entire business is based on specific open-source software projects. They typically earn revenue by providing value-add software, services, special licenses, or fully managed versions of the software.
