Jamie Denenberg has joined Alpine Labs as partner and chief strategy officer, with a focus on the growth of the company, which produces for network, cable and digital platforms.

Alpine Labs, formerly Ketchum Labs, has an alliance with BlackBoxTV that includes the scripted reality/competition series “Fight of the Living Dead,” in which YouTube celebrities are pitted against zombies, and the feature film “Villisca,” about the earliest documented killing spree in the United States. Alpine Labs and its principals, Kevin Abrams and Patrick Weir, are executive producers of the upcoming syndicated series “The Pinkertons,” about the famous detective agency.

Denenberg most recently was partner in the marketing company SA Entertainment, with clients including Warner Bros., Summit Entertainment, HBO, Imax and The Weinstein Co. She transitioned to a career in entertainment from politics. She was California finance director for then-Sen. John Kerry’s 2004 presidential campaign, and her responsibilities in raising millions for his bid also included Oregon, Washington, Utah and Nevada. She was an early bundler for Barack Obama’s 2008 presidential bid, and was among the hosts and organizers of events targeted to young Hollywood.

In an interview, Denenberg said that “any success I might have in the entertainment business I completely trace back to that job on the Kerry campaign,” noting her work with high-profile donors in a fast-paced environment. Denenberg was recently named a partner in the company, after having originally serving as a consultant.

In a statement, Abrams said that “as we continue to find original ways to fuse content creation with digital distribution, Jamie’s unique skill sets and vision make her the perfect person to take us into this new era of media and its consumption.”

Denenberg has previously been an executive at Relativity Media and Overture Films, where she was responsible for content creation for viral, multimedia and awards campaigns. She also served as an executive at Sony Pictures Home Entertainment, where she helped plan the studio’s worldwide DVD releases.
