Alexander Cho
Senior Performance Marketing Executive · Programmatic & CTV · NYC
Summary
I am a performance marketing executive with a decade of experience driving scalable growth across paid social, programmatic, and CTV portfolios exceeding $50M. My career has been defined by a commitment to measurement rigor and the transformation of complex media ecosystems into repeatable revenue engines. At Omnicom Media Group and Spark Foundry, I’ve led enterprise-wide investment strategies for global giants like Nissan, L’Oréal, and Dyson, consistently delivering double-digit growth in acquisition and ROAS. I specialize in building high-performing in-house teams and advancing incrementality through sophisticated attribution modeling and SPO consolidation—notably reducing MFA site exposure to under 1% while expanding incremental reach by 28% through CTV scaling. Beyond traditional media, I am currently pioneering the use of Generative AI to accelerate creative validation and audience optimization. Whether it was launching HBO’s Westworld to record-breaking viewership or managing $750M in new business wins, my focus remains on balancing brand equity with hard performance accountability. I thrive at the intersection of product, analytics, and activation, ensuring every dollar of spend is backed by a data-driven 'test-and-learn' framework that translates directly into executive-level business outcomes.
