Remember back in January when we said that the founders of Baltimore’s Millennial Media, Chris Brandenburg and Paul Palmieri, would become Baltimore’s next Kevin Planks? (See our post  IPO to Make Instant Millionaires Out of Millennial Media Founders.) Well, it has happened.  The company’s initial public offering was yesterday and shares in the company started at $13 and doubled by the end of the day.  Both co-founders are now worth, on paper, over $100 million.  Not bad for a couple of tech geeks from Baltimore and Harford counties.  Just kidding guys; we’re just jealous.

Millennial Media is an advertising network for mobile devices.  It is the third largest mobile ad network in the U.S. with offices in London, New York, Singapore, San Francisco, Washington, D.C., and Atlanta.  Company headquarters are on Boston Street in Canton.
