Tim Cadogan

Tim Cadogan is best known in the AdTech industry for his tenure as CEO of OpenX, one of the world's largest independent ad exchanges, where he built the company into a credible, publisher-aligned alternative to Google's ad exchange ecosystem. During his leadership from 2014 to 2020, Cadogan navigated some of the most turbulent years in programmatic advertising, steering OpenX through the rise of header bidding, the push for supply path optimization, and growing industry pressure around transparency and brand safety. His consistent advocacy for open standards and fair marketplace dynamics earned him a reputation as a principled operator in an industry often criticized for opacity. Prior to OpenX, Cadogan held senior roles at Yahoo, most notably as Senior Vice President of Advertising and Commerce, where he oversaw one of the largest publisher-side ad technology stacks in the world. His responsibilities spanned display, mobile, and video advertising products during a pivotal era when programmatic buying was displacing traditional direct sales. This experience gave him deep fluency in both the buy-side and sell-side dynamics of digital advertising, informing his later work building exchange infrastructure that balanced the interests of buyers and sellers. Since 2020, Cadogan has served as CEO of GoFundMe, transitioning his marketplace and platform expertise to the crowdfunding sector. While his current role sits outside AdTech, his legacy in the industry remains significant — particularly his efforts to preserve independent exchange infrastructure at a time when consolidation threatened to cede the open web's monetization layer entirely to a handful of dominant platforms.
