Second last on today's CIX Top 20 roster is PostRank and their CEO Carol Leaman. Founded in 2007 and based in Waterloo, PostRank (originally AideRSS) monitors and collects social engagement events correlated with online content in real-time across the web.
PostRank gathers where and when stories generate comments, bookmarks, tweets, and other forms of interaction from a host of social hubs. Publishers and people interested in their content use PostRank Data Services and Analytics to gauge influence and reach with audiences.
PostRank offers a collection of APIs for networks, companies, agencies, and application developers that enable real-time content and engagement access for media monitoring, analysis and aggregation. On the analytics side, PostRank is a social web analytics tool for publishers, enabling more effective discovery of where their audience is engaging with their content.
PostRank's consumer offering allows users to discover the best blogs, news, and articles by topic and compare engagement performance among a group of sites by topic.
In December 2008, PostRank closed its second round of financing with Waterloo's Tech Capital Partners.
