Why it was a Fierce 15: Qpass was selected for its activity management software that allowed carriers to launch and manage all aspects of their mobile data solutions--from content partner relationships to payment collection and settlement to reporting and customer billing--without changing their existing billing systems. Qpass had already racked up key carrier partners including AT&T Wireless and Cingular, and had forged relationships with content firms such as Handango and the Walt Disney Internet Group.
