Watch for these two names: Paul Palmieri and Chris Brandenburg.  Both are poised to become Kevin Plank-important, and soon.

With the filing last week of the necessary documents for an initial public offering of Millennial Media, the Baltimore-based mobile ad network is sure to make multi-millionaires of its 40ish founders โ€” Palmieri and Brandenburg. The documents put the value of the company at $305 million. And itโ€™s just the beginning. See filing at Citybizlist

Five-year-old Millennial Media is the largest independently owned mobile ad network, with offices in Baltimore, London, DC, New York, San Francisco, Los Angeles and Singapore. Its two major competitors โ€” Admob and Quattro โ€” are owned by tech giants Google and Apple. According to TechCrunch, Millennial has seen growth of 138 percent in the last year with revenues near $70 million in the first nine months of 2011. Net losses, meanwhile, declined from $5.4 million to $417,000. 

While the company and its co-founders are well-known in the tech community โ€” both have been the recipients of too many awards to list here โ€” they are less known in and around Baltimore.  Palimieri graduated from Mount St. Maryโ€™s College in 1992 and lives in Hunt Valley. Brandenburg is a UMBC grad, who is from Harford County.

So if youโ€™re a development director looking for deep-pocketed board members or a scientist in search of someone to fund your latest study or a just an ambitious artistic visionary in search of a patron, you should probably friend these guys on Facebook, or better yet, connect with them on LinkedIn. But donโ€™t get hurt feelings if they ignore your request. Theyโ€™re kind of busy right nowโ€ฆ
