AdCellerant has appointed
Allen Klosowski as Chief Operating Officer, underscoring its focus on AI-driven ad tech and digital marketing.
Klosowki will lead operational strategy, product innovation and customer
operations.
Most recently, the new hire served as senior vice president at Epsilon, where he shaped strategy and led product teams across digital and retail media, clean-room data
collaboration and measurement. He also built Epsilon's first AI-based product-operating model.
Prior to Epsilon, Klosowski held leadership posts at Amazon, where he helped develop the
company's media-planning tools for streaming TV, accelerating the shift of advertiser spend from linear TV to Amazon's DSP.
"Over the last 13 years, we've built AdCellerant into one of the
industry's leading technology-enabled advertising platforms by making sophisticated digital marketing accessible to organizations that historically lacked enterprise-level solutions," said Brock
Berry, AdCellerant CEO. "Allen is exactly the leader we want as we invest in the talent, technology and innovation that will define the next generation of advertising."
