We do have a beacon that reports anonymous statistics to us as well as giving us an estimate on unique installations. That said, it's an optional feature, and its only in newer versions. One thing that is generally true is many companies don't update frequently so we end up not getting a large chunk of data due to them running on older versions. If take only our data (ignoring anyone who isnt actively reporting to us), It's a fairly close 50% split of on-premise companies to hosted customers. That said, our estimate is its more around 30% of users run off of getsentry.com, and the other chunk runs on-premise.
