Jaxtr Ends Beta, Begins Selling Ads

Social voice startup Jaxtr has reached 10 million users, doubling its user base in less than three months. The company has also announced the end of its beta and the beginning of revenue, with ads running on the Jaxtr Cafe site. The site essentially turns Jaxtr from an widget-based mobile VoIP platform into a one-stop shop for social voice and text messaging that can be delivered to a mobile phone without the user giving out his or her phone number.
