McLean, VA-based Mobile Posse, a mobile ads provider, has raised a $10 million second round led by Softbank Capital, with participation from Court Square Ventures, Columbia Capital, and individual investors. Last year, it raised $1.5 million, bringing the total to $11.5 million. The company focuses on delivering ads and content to a user’s phone when it is idle, claiming this model achieves high user response and increased ARPU for carriers. The company recently announced a full rollout with Ohio-based operator Revol, and plans to use the latest funding to implement its service with more carriers. Revol has said it will offer a handset discount for users that opt in to the system. Mobile Posse CEO and founder Jon Jackson was formerly an executive at AOL (NYSE: TWX). Release.
