Konrad Feldman is the co-founder and CEO of Quantcast, a company he has built since 2006 into one of the most influential AI-powered advertising technology platforms in the world. Quantcast processes data across more than 100 million web destinations and has become a defining force in programmatic advertising, real-time bidding, and audience measurement. Feldman's distinctive contribution has been applying rigorous machine learning and data science to the challenge of understanding and reaching digital audiences at scale, long before such approaches became industry standard. Under Feldman's leadership, Quantcast has navigated multiple industry inflection points — from the rise of programmatic advertising to the deprecation of third-party cookies — consistently positioning itself at the frontier of privacy-conscious identity solutions. He has been a prominent voice in shaping the industry's response to post-cookie advertising, championing approaches that balance advertiser effectiveness with consumer privacy. Quantcast's Choice platform, a consent management product, reflects his commitment to building infrastructure for a privacy-first web. Before founding Quantcast, Feldman honed his strategic thinking as a consultant at McKinsey & Company, advising technology and media clients. His academic credentials — degrees from the University of Cambridge and Stanford University — gave him a rare combination of technical depth and business acumen that has defined Quantcast's product-led, data-science-first culture. He is widely regarded as one of the foundational builders of the modern AdTech ecosystem.
