NewsGator was founded by 2004 by Greg Reinacker in 2004. The NewsGator product was an RSS news aggreGator. They acquired FeedDemon, and NetNewsWire. The product was initially for a consumer use, but they added an enterprise version with tools for syncing and collaboration, which evolved into their Social Sites product. At some point after their acquisition of Sitrion the company changed their name to Sitrion as their focus was no longer on RSS aggregation and syncing. Sitrion is now part of Limeaid.
