Millennial Media (NYSE: MM), the leading independent mobile ad company, today announced that former Sociomantic and Admeld executive Jason Kelly is joining as President of the Company’s Managed Media business. Reporting to CEO and President Michael Barrett, Kelly will be responsible for leading the Company’s global brand and performance sales teams. Kelly is expected to join the Company in mid-October.

”As we move to a mix of traditional media and programmatic buying, it is vital to have someone run that business who has tremendous expertise in both areas,” said Barrett. “Jason and I worked together at Admeld before our acquisition by Google and he continued as Chief Revenue Officer afterward, driving a successful and scaled business. His proven track record of sales leadership in complex, fast-growing markets makes him the ideal candidate and we’re thrilled to have Jason on board to lead our efforts.”

Kelly brings a tremendous depth of knowledge and experience to Millennial Media. Most recently, Jason was CEO of Sociomantic, a company that helped some of the largest retailers with their e-commerce strategies through re-targeting and programmatic solutions. Sociomantic was recently acquired by Dunhumby, a UK-based company and Tesco subsidiary. Prior to Sociomantic, Jason held executive sales management positions at a number of leading global brands - including Google/Admeld, Time Inc., RAPT (a Microsoft subsidiary) and Virgin America. He will be based in New York.

“We’ve never been in a more exciting time in mobile, with programmatic products giving us new solutions for brands and agencies,” said Kelly. “Millennial Media’s strategy to build the leading independent and fully mobile marketplace positions us to capture a larger share of this increasingly important advertising market. I’m excited to lead the Company’s sales team as we help the world’s largest marketers reach their audiences in mobile.”

This addition to the leadership team underscores the importance of Millennial Media’s traditional managed media business even as it expands its programmatic capabilities. Last week the company announced it has signed a definitive agreement to acquire Nexage, one of the world’s leading SSPs and RTB exchanges. Kelly’s experience in both arenas gives him tremendous strength to lead the sales team as the industry evolves.
