Over the last couple of years a number of different open source business strategies have evolved. According to the 451 Group, it's an evolution that includes the broader adoption and usage of open source overall by both open source and proprietary software vendors.

GoAhead Software Moves to Open Source Business Model. GoAhead® Software today announces that it is shifting its business model and technology strategy from its proprietary SAFfire product to an open source software model. Simultaneous with the move to open source, GoAhead is announcing the acquisition of Avantellis from Emerson Network Power.

The Open Business Foundation (OBF) operates on two premises: that the open source development community makes good business sense, and that small businesses can be more successful if they band together with each other to share resources of all kinds.

Most software developers have little interest in entrepreneurship, but an open-source software project will survive and thrive only by delivering value into a market (users) with business partners (contributors) and against competitors (other open and closed source software). If you want to run a successful open-source project, it helps if you consider the key questions that apply when defining a commercial business model. I'll expand on Chesbrough's and Rosenbloom's list of 6 themes to demonstrate why.

OpenITWorks CEO Michael Grove contends that it is a mistake to think of commercial open source as its own business model. Instead, open source is one of many possible means to an end of making a single software business model successful -- that of selling value to customers through software. Businesses should focus their strategic planning on how to best monetize their value propositions, through open source or something else.

Everyblock, which sorts police reports, public records, and news by address, is going open source and looking for a business model.

I’ve talked in the past about a number of “open source” business models. There’s the MySQL “dual license” model, where all the software is available under an open license but a proprietary license can be purchased.

So what happened to open source as a business? There was a wave of “commercial open source” companies that were going to change the world, including SugarCRM, Alfresco, Jasper, Pentaho, and ActiveGrid, a company I started in 2003 to bring open source software into businesses.
