Bio

Ruben Schreurs is one of the AdTech industry's most recognized advocates for programmatic transparency and media supply chain integrity. As Chief Strategy Officer at Ebiquity, a leading independent media investment analysis firm, he has shaped how major advertisers audit, evaluate, and optimize their programmatic spending. His work has helped bring systemic issues around hidden fees, made-for-advertising (MFA) sites, and opaque intermediaries into mainstream advertiser consciousness. Schreurs joined Ebiquity through its acquisition of Digital Decisions, a programmatic consultancy he co-founded and led, which specialized in helping advertisers understand and improve the quality and efficiency of their digital media investments. His hands-on experience building programmatic audit frameworks gave him a practitioner's credibility that distinguishes his commentary from purely theoretical analysis. At Ebiquity, he expanded this work to a global scale, influencing how the firm approaches media transparency mandates for multinational clients. A prolific contributor to trade publications including The Drum, Campaign, and AdExchanger, Schreurs is known for data-driven critiques of programmatic waste and advocacy for advertiser-side accountability. He has been a consistent voice at industry events and in policy discussions around supply path optimization, ad verification, and the responsibilities of both buy-side and sell-side participants in cleaning up the digital advertising ecosystem.
