Stealthy 33Across, a startup that uses an algorithm to identify which online users are the most influential of others' behavior, announced that it has raised $750,000 of an expected $1.5 million in second-round funding, according to peHUB. The New York-based company, which also lets its clients target messages to these users, says its platform "enables performance and brand marketers to activate the social web."
