Lotame, an Elk Ridge, Maryland-based advertising startup, has closed its second funding for its social media ad platform, Crowd Control. Motto, and I quote: “Every Party Needs Crowd Control!”

The company claims that its technology allows brands to tap into audiences that have proved they’re interested in certain subjects. It’s working with sites including Flixster, Fotolog, and The Huffington Post — in total, 53 million users, it claims. The company uses cookies to track anonymous user data like age and location, and what they looked at. Then, it lets an advertisers run ads to reach particular types of users through Lotame’s network.

It has only been six months since Lotame closed its first funding, a notably short period of time. Emergence Capital Partners led the $13 million investment. Also participating were previous investors Battery Ventures and Hillcrest Management.

Here’s more, from an interview by Wallstrip with founder, chief executive and Advertising.com veteran Andy Monfried.
