Social game and app analytics firm Kontagent now tracks over 100 million Facebook users, over 500 million daily “event messages”, and over 15 billion messages per month through its Kontagent Social Event Tracking Platform. That means Kontagent has partnered with enough top social games and apps to be tracking the activity of roughly one out of every six Facebook users. At this time in 2009, Kontagent’s platform tracked only 2 million users. One year ago, Kontagent tracked roughly 30 million users. Kontagent says that many of its current partners signed up in the past three months, after the company rolled out version 2.0 of its product.
