If you think of open source software as being primarily the work of hobbyists and lone developers, your impression is sorely out of date. While independent developers are still an important part of the open source community, today much of the work on open source projects is being done by corporate developers.
In a recent appearance at the Open Source Summit, Linux founder Linus Torvalds acknowledged this corporate influence and welcomed it. "It's very important to have companies in open source," he said. "It's one thing I have been very happy about."
The list below highlights some of the leading for-profit companies that are using, sponsoring and contributing to open source projects. It includes a mix of large enterprises, small startups and everything in between. Some of the companies exclusively offer products based on open source software, while others sell a mix of proprietary and open source solutions. But all of these companies play a significant role in the open source community.
Please note that this is not a ranking; the companies are arranged in alphabetical order. If you think we left off a company that should have been on the list, feel free to make your case in the Comments section below.
