Apple’s Mike Pallad is to join ad tech firm Undertone as chief revenue officer, with Diane Malloy also arriving as vice president of programmatic sales and strategy, as part of a reshuffle aimed to drive growth and performance.

Pallad previously worked at Apple Music and iAd in a sales management role, while Malloy joins from PubMatic where she was vice president of global media solutions.

Malloy is the second shift from PubMatic this week, following global chief revenue officer Rob Jonas’ move to Factual.

“With its focus on unmissable high-impact formats and creative, quality media and brand-centric technology, Undertone has taken a unique and incredibly valuable approach to digital advertising,” said Pallad. “I am beyond excited to share this vision with the world’s biggest brands.”

“Mike and Diane’s senior leadership and key market expertise and relationships add to an award-winning sales and service organization that has already been operating at a very high level,” said Undertone chief executive officer Corey Ferengul.

“They will be a key part of our mission to bring our beautiful and engaging advertising solutions to brands and agencies and continue to lead the market in high-impact digital advertising.”

Undertone was acquired by Perion Network in December last year, as part of a $180m deal.
