PageLever is a analytics tool for Facebook Fan pages that takes Facebook Insights and adds more analytics, like how many of your fans are using mobile devices.
PageLever officially launched at the beginning of August, and since then we've seen explosive growth: Our customers include YouTube, MTV, etc -- we are used by a ton of large brands, including four of the top 10 Facebook pages. Currently, we measure more than a quarter of a billion fans across the Facebook pages of our customers.
We were part of the Ycombinator Summer 2011 Class. Our investors include Ron Conway and Yuri Milner -- both early investors in Facebook.
PageLever was started by two guys who used to consult for large brands on how to succeed on Facebook. They were the guys who helped the Redskins become the fastest growing page in the NFL, and they helped YouTube become the fastest growing page in all of Facebook.
But they kept getting frustrated because none of the social media analytics tools measured what they needed. So they started building PageLever.
