New leaders will accelerate growth of OpenXSelect™ and build on the company’s foundations of quality inventory, innovative data excellence, and superior performance

OpenX Technologies, Inc., one of the world’s leading omnichannel supply-side platforms, today announced a strategic expansion of its leadership team, appointing five senior executives across product, marketing, communications, and operations.

This expansion reflects OpenX’s commitment to three core foundations: delivering transparent, high-quality inventory; driving innovation in data; and ensuring superior performance that directs more budget into working media. Together, these executives will help scale OpenXSelect™, the company’s next-generation curation and supply-side targeting platform, simplifying the complexity of programmatic and making media work better for buyers and publishers alike.

Joining OpenX are:

• Sethu Balasubramanian, Vice President of Product
• Nick Van Amburg, Vice President of Product Marketing
• Tiffany Tai, Vice President of Communications
• Nate Fishler, Vice President of Global Solutions and Technical Operations
• Emily Kramer, Head of Agency Curation and Commerce Media

"Programmatic, and even curation, have remained overly complicated for the people buying and selling media,” said John Gentry, CEO of OpenX. “AI is giving us the chance to simplify what has been too complex and make our customers’ and partners’ jobs easier. However, technology alone isn’t enough. It requires people with deep product expertise, customer focus, clear communication, and the ability to innovate and maximize value to build intelligent ad tech and champion our high standards for quality, performance, and responsibility. With these new leaders, OpenX is doubling down on our mission to make media work better for buyers and publishers."

Sethu Balasubramanian, Vice President of Product

A seasoned product leader with over three decades of experience across TiVo, Undertone (Perion), Cadent, and Xandr (Microsoft), Balasubramanian will lead product development for OpenXSelect and its self-serve infrastructure.
