Ari Rosenberg

Ari Rosenberg is one of digital advertising's most persistent and influential contrarian voices, best known for his decades-long campaign to move the industry away from CPM-based pricing toward performance-based compensation models for publishers. As founder and CEO of Performance Pricing Holdings, he has institutionalized this philosophy into a business dedicated to restructuring how publishers and advertisers transact, arguing that CPM pricing misaligns incentives and undervalues quality editorial environments. Rosenberg has been a fixture in the digital media industry for over two decades, having held senior sales and business development roles at major digital publishers before turning his focus to advocacy and entrepreneurship around pricing reform. His column, Online Publishing Insider at MediaPost, has served as a long-running platform for challenging conventional wisdom on ad pricing, publisher monetization, and the structural flaws he sees in programmatic advertising's race to the bottom. He is widely respected as a thought leader who combines operational experience with a willingness to publicly critique industry norms that others accept uncritically. His work has influenced conversations around publisher value, advertiser accountability, and the sustainability of ad-supported media business models.
