About Marchex

Marchex, Inc. delivers customer calls to businesses and analyzes those calls so companies can get the most out of their mobile advertising.

Marchex supports its customers through a unique technology platform that has three primary components: (1) Call Analytics, which powers all of Marchex’s advertising solutions, and allows partners to leverage data and insights that accurately measure the performance of mobile, online and offline call advertising; (2) Digital Call Marketplace, which annually connects hundreds of millions of consumer calls to advertisers from a range of mobile and online sources on a Pay For Call basis; and (3) Local Leads, a white-labeled, full service digital advertising solution for small business resellers that drives quality phone calls and other leads to their small business advertisers.

On November 1, 2012, Marchex announced its intention to pursue separation of its business into two distinct, publicly-traded entities.
