Part of the fun of PyCon is Startup Row, where we highlight the most promising Python-using startups and give them time and space at PyCon to show their stuff. After a massive response last year, we decided to bring back Startup Row and make it a tradition.





Well, like everything else this year at PyCon, Startup Row was packed. We received several times as many applicants as we had slots - and all were strong contenders. It was hard to pick, but our panel was able to winnow the field down to just twelve winners - and two of these stood out to become the judge's picks for 2012. The winners for PyCon 2012 Startup Row are:





Exhibiting Friday

(Judge's Pick - Saturday):
