While many of us may understand the distinction between Because Of and With companies, there are still many unanswered questions as to the right business models to use for Because Of companies. As with most of opensource (and some will say it should be all of opensource, and I tend to concur), Because Of companies are really about infrastructure and utility.
I have always maintained that With companies undergo a transition to Because Of companies over time, particularly if they are successful to a point of dominance in a given market.
Sean’s post musing on capital structures makes interesting reading in this respect, and raises some critical questions. The particular companies mentioned should only be used as examples to illustrate the point, the issue relates to all Because Of companies.
If you want to understand more about Because Of Rather than With, you may find this post useful.
