Ohloh is great tool to analyze Open Source project repositories
Since we have moved from Sourceforge to ObjectWeb (now renamed OW2) – and at the same time moved from CVS to SVN – we had 100 contributors and over the last 12 months we had 92 contributors.
We can compare that with Firefox for instance which had 136 contributors in all its history and 80 during the last 12 days.
Of course with those numbers, Ohloh puts us in the 2% largest Open Source projects!
The next image compare the number of contributors for projects like Firefox, JBoss AS and eXo. The most impressive here is the growth!
Among all those contributors, most of them have been employed by eXo Platform SAS since and we continue our tremendous growth while other startups starts to layoff employees.
We now are 85 and hope to be more than 100 by the end of year, so once again if you are interested feel free to contact us.
