GraphEffect, a social marketing software company, announced new Twitter offerings at the ad:tech conference in San Francisco, where the company has been nominated as a “Start Up Spotlight Finalist.” GraphEffect’s AudienceBoost is the first offering that allows a scalable solution for brands to run advertising campaigns on Twitter. It enables brands to uncover new interest targets for their Promoted Tweets and Promoted Accounts. American Express and Digitas beta tested the new offering during last month’s successful American Express Twitter Sync campaign.

The ad:tech Startup Spotlight Series is back -- this time, with brand partners including Gap, Inc., GE and Unilever -- and the call for entries has kicked off. The Startup Spotlight Series is a hunt for the most enterprising new companies in digital marketing, and the competition goes live at ad:tech New York in November. Startups can submit to compete in one of four challenges: Gap Shopper Marketing, Unilever Mobile Commerce, GE Data & Analytics and Social TV & Video. Submissions are being accepted now through Friday, August 24.

After more than one year in development, Altitude Digital, a leader in online display advertising, is officially releasing its robust and one-of-a-kind video platform, Visualtising, at the ad:tech conference in New York.
