Ad server and tech company Flashtalking has appointed John Nardone as chief executive.

Nardone will be responsible for ensuring continued momentum and product innovation. He will be based in New York.

Nardone was formally chief executive at [x+1] since 2008, and following its acquisition by Rocket Fuel, he helped to grow the business into a respected data management platform. Rocket Fuel acquired [x+1] for $230m in a transaction that was announced last August.

Paul Cunningham, founder and chairman of Flashtalking said: “John’s appointment comes at an exciting time for Flashtalking and will help push us forward globally. Our clients and revenue are growing dramatically, especially in the US market.

“Obviously, we’re eager to extend this growth even further. John has a fantastic pedigree and track record. He will help take Flashtalking to the next level.”

Nardone has served as one of the founding board members of the Internet Advertising Bureau (IAB) and on the board of DMG Media.

Nadone said: “As programmatic media buying grows to new heights, advertisers need an ad serving partner who can meet the challenge of injecting relevance into every ad message.

“Flashtalking is that partner, and I’m looking forward to helping develop strategies to support and accelerate our growth.”
