At the very end of 2009, Gartner, Inc., the world’s leading IT research and advisory company, made a rather sizable prediction about the future of open source software.

The popularity of using free rather than commercially-licensed products would grow, but one particular segment would see a dramatic increase. Gartner predicted that the deployment of open source business intelligence tools would become five times larger by the end of 2012.

Clay Loveless, founder of Jexy and co-founder of Mashery, would seem to agree with that estimate. In an interview with, Loveless pointed out that he hardly comes across any SMEs which don’t leverage open source software in some significant way.

But since we are still so wedded to big name commercial software, some small business owners and entrepreneurs probably haven’t yet taken advantage of these free software tools.

Small Business Open Source Solutions -- Choose What's Right for You

Keep in mind that some of these companies offer multiple editions of their products under open source and commercial licenses. Sometimes the software can be totally free, but you have the option to purchase extra individual features or add-ons.

It’s best to have a thorough look around each company’s Website so you know exactly what’s included in each edition. Even if it’s free, you still want to know what it does.

The growing offering of open source business tools clearly reflects how the open source movement, which goes back to the late 70s and early 60s, has become such an important part of mainstream technology culture.

As a parting shot in his interview, Loveless also pointed out that Yahoo!, Facebook, and Twitter all built their companies on the back of open source.

“It’s hard to argue,” he said, “that you really need commercial tools to make it big.”
