Background

About Ben Ierien

Director of Performance Marketing with 15 years of experience leading acquisition and growth across multi-channel paid media. I’ve owned performance strategy and execution across multi-million dollar budgets, building scalable acquisition systems that drive measurable improvements in efficiency and return on spend. My work has consistently delivered double-digit gains in CPA and ROAS through structured testing, incrementality frameworks, and disciplined optimization. I specialize in measurement and decision-making. I use incrementality testing, geo experiments, and signal optimization to separate true growth from demand capture, ensuring spend is allocated based on actual business impact, not platform-reported performance. Most marketing organizations over-index on attributed conversions and optimize to misleading signals. I focus on correcting that by building systems that tie spend to incremental outcomes and long-term unit economics. My experience spans sports, technology, and ecommerce, supporting brands including Nike, Vrbo, Expedia, Yahoo, Discover, and the U.S. Olympic Team Trials. I operate across both strategy and execution, translating complex performance data into clear, actionable decisions that drive scalable and sustainable growth.
