Cloudera will soon be a publicly held mostly-open source company valued well over a billion dollars. Hortonworks is already public and almost fully-open source, although their market cap is under a billion ($670MM today). Edit: I missed that the billion refers to revenue, and that RedHat is >2 billion. That's extremely impressive! These data platform companies are doing well, but I think they're still doing far under a billion in annual revenue.
