Data First. Then AI.
Dennis Buchheim is Global Head of GTM for Adtech, Martech, Communications, Media and Entertainment at Snowflake. He has spent over 20 years shaping the infrastructure of digital advertising, from building a proto-AdSense before Google, to leading product and policy at Yahoo and AppNexus/Xandr, to defining standards at the IAB Tech Lab.
“There is more data available today than there has ever been. For better and for worse, the scaffolding is all there now.”
Dennis Buchheim is a product-oriented leader who has spent more than two decades shaping the infrastructure of digital advertising. He is Global Head of GTM for Adtech, Martech, Communications, Media and Entertainment at Snowflake, where he helps companies unlock the power of data collaboration and AI across the advertising and media ecosystem.
Buchheim’s career traces the arc of digital advertising infrastructure itself. He built ad products at a dot-com before Google existed, leading what was essentially a proto-AdSense. He then spent years at Yahoo and AppNexus/Xandr building programmatic and data capabilities. At the IAB Tech Lab, he served as CEO and shaped the standards that govern how data and identity work across the open web.
At Snowflake, his focus is on the composable data ecosystem that lets companies collaborate on data without moving it, power AI on top of their first-party signals, and navigate a privacy-forward world where consent and transparency are table stakes rather than afterthoughts.
“Business users can now talk directly to data without waiting in the data science queue.”
If you don’t have your AI story together either, you are going to fall behind.
The companies racing to deploy AI without a coherent data strategy are building on sand. Snowflake’s architecture is premised on the reverse: get the data right, make it collaborative and accessible, and then AI becomes genuinely powerful rather than a capability bolted onto a broken foundation.
It is not the monolithic solution. It is using best-in-class tools that work together.
The era of the all-in-one marketing platform is giving way to something more flexible. Buchheim’s argument is that companies should build ecosystems of specialist tools that collaborate on a shared data layer, rather than betting on a single vendor to do everything adequately. Composability is the new competitive advantage.
We wanted to leapfrog compliance and turn privacy into a genuine competitive advantage.
The instinct to treat GDPR, CCPA, and data clean rooms as legal overhead misses the strategic opportunity. Buchheim’s view is that brands and platforms that invested early in consent-based, first-party data infrastructure are now better positioned for AI deployment, partner collaboration, and consumer trust than those that did the bare minimum.
