I would second this. We currently run an open-source project (distributed storage) and commercial venture based upon it, but the open-source was the driver done because we thought that it was an important problem to solve and that it would be worth more as open-source than as a proprietary product. Our commercial venture arose by choosing one specific application of the code and building a business to address it. Note that our open-source project is something that we (and others) have worked on independently of the commercial venture. The community is separate (though aware) and drives the open-source project in directions that we did not expect.
