Mobile ad network Ringleader Digital has, well, ditched its mobile ad network with the intent of reinventing itself as a technology company. Rather than pushing ads on mobile Web sites, Ringleader will now market its Spark Server ad-serving platform and its Media Stamp software that collects information from browsers so marketers can target ads by context, geography, time of day, device and other demographics. Ringleader promises that none of the collected data unveils any "personally identifiable information," MediaPost reports.

According to the article, the company sold its ad network to Access Mobile Advertising, a new company created by former Ringleader VP of ad sales Kristine Latronica.
