Authentic Brands Group has brought Amazon executive Tim Derner on board as its new global head of marketplaces.

Derner had been at Amazon for more than a decade, serving most recently as director of Amazon Fashion and Luxury Stores where he played a pivotal role in transforming that division into the world’s largest fashion retailer.

During his time there, he worked closely with Authentic to significantly expand the online presence of several of its brands including Reebok, Brooks Brothers, Eddie Bauer, Aeropostale and others.

At Authentic, Derner will spearhead the expansion of the company’s global distribution strategy, with a focus on strengthening partnerships, accelerating brand reach and driving incremental value across platforms, the company said. He reports to Matt Maddox, president, and will work closely with Adam Kronengold, chief digital officer, and Jarrod Weber, global president of sports and lifestyle.

“Marketplaces are a critical engine for long-term brand growth,” said Maddox. “Tim’s track record of building high-performing teams and scaling digital marketplaces worldwide makes him the ideal leader to deepen our capabilities in this space. His appointment marks a significant step in making this channel a cornerstone of our global distribution strategy.”

 “Authentic has built an unparalleled portfolio, and there’s an incredible opportunity to reimagine how iconic brands show up on global marketplaces,” Derner said. “We’re just scratching the surface of what’s possible when great brands are optimized for discovery and conversion at scale, and I’m thrilled to help build on that momentum through world-class marketplace execution.”

Authentic owns more than 50 brands and generates about $32 billion in annual retail sales.
