Selling open source just keeps getting easier
One way to know that the open source market is maturing is to analyze how fast companies are able to get to significant revenues. By "significant" I mean $10M and on a sharp, upward ramp. When I started in the business of open source (2000, with Lineo), it was horribly difficult to pull in $1M in revenues, much less $10M.
Now? The ink will still be dry on your VC term sheets when you cross that threshold. Really.
