Konrad Feldman is the co-founder and CEO of Quantcast, the San Francisco audience-intelligence company he started with Paul Sutter in 2006. A London-born computer scientist with a UCL PhD in neural networks, he was building machine-learning systems for banks two decades before AI became a marketing department buzzword. Today he is making the case that advertising, done with better data and smarter models, is what keeps the open internet open.

Luis Hernandez Garrido is the co-founder and CEO of Uptodown, the world's largest alternative app store, which he launched in 2002 as a university project in Malaga, Spain. Over two decades he has grown it into a platform with 130 million monthly active users and 450 million APK downloads per month - all without a single outside investor. Now based in Berkeley, California, he champions open internet principles, device neutrality, and democratized software distribution, and is an active voice in the Coalition for App Fairness pushing back against Google and Apple's app store dominance.
