Wikimedia Commons has media related to Free software companies.

Articles in this category are about software companies whose primary focus in the promotion of software is on promoting free software.

Free software is software which can be used, studied, modified, and redistributed by all recipients. This requires that it is distributed under a free software license. Free software is sometimes also called "open-source software", though many developers prefer to make a distinction between the two terms.

Some of these companies make their profits through sales, some through related services, some through development on demand, and some have other business models. The characteristic that they share is that the focus of their public statements - in advertising, conference participation, etc. - is on free software itself (not proprietary software additions).
