Data and AI Are the Foundation of Everything for the Foreseeable X Years
Dennis Buchheim, Global Head of Go-to-Market for AdTech and MarTech Communications, Media and Entertainment at Snowflake, on a 20-plus-year journey through ad tech that encompassed building one of the first contextual ad systems pre-Google, leading programmatic strategy at Yahoo, running IAB Tech Lab as CEO, working inside Meta on advertising ecosystem standards, and why he ended up at Snowflake.
Dennis Buchheim, Global Head of GTM for Adtech/Martech, Communications, Media & Entertainment, Snowflake. In conversation with Justin Cooke.
Data and AI Are the Foundation of Everything for the Foreseeable X Years
0:0034:00Why 20 years building every layer of ad tech from the inside leads to Snowflake as the place where it all converges
Dennis Buchheim started in software engineering, moved through product management at Apple and Oracle, co-founded iHarvest during the dot-com boom where he built a contextual advertising system before Google AdSense existed, spent years at Yahoo building programmatic strategy including launching the Yahoo DSP, served four years as CEO of IAB Tech Lab developing the privacy and identity standards that underpin modern programmatic advertising, then spent time at Meta leading advertising ecosystem initiatives before joining Snowflake.
In this conversation he traces how each stage of that journey contributed something necessary to what came next, why he describes his role at Snowflake as fitting like a glove, and why the combination of data infrastructure and AI is, without hyperbole, the foundation of everything in marketing and advertising for the foreseeable future.
Tell me about the very beginning of your advertising career
“I co-founded iHarvest during the dot-com boom. We needed ways to fund what we were building, so we created a contextual advertising solution to make a little money off our own software. This was before Google AdSense existed. We created a really hacky version of it. That was the inkling that there was something here.”
The proto-AdSense moment that started a 20-year journey.
Tell me about the programmatic strategy work at Yahoo
“The most notable part of my time at Microsoft was getting Microsoft into the programmatic space in 2009-2010. We invested in App Nexus and made Hotmail and MSN inventory available through the ad exchange. Premium publishers were not doing this. That was quite an interesting journey. Then back to Yahoo and the most notable moment was putting forward the strategy to build a DSP.”
The early programmatic moves that shaped the modern ecosystem.
What did running IAB Tech Lab teach you?
“We had to evolve OpenRTB to enable real-time bidding. Evolve taxonomies for consistent data communication. Get very deep into privacy-compliant identity resolution. Sort of like USB and Wi-Fi are protocols, we had to create protocols for advertising. It was an incredible four years.”
The standards layer of the ecosystem.

“When the Snowflake opportunity came up, I was like, well, I don't know. But it feels like it fits like a glove at this point because it is the combination of data and AI, which I think with basically no hyperbole I can say is the foundation of everything for the foreseeable X years.”
The synthesis of a 20-year career in one platform.
What is the most important lesson from 20-plus years in ad tech?
“Standards and trust. The industry works when participants can trust each other and when there are shared protocols for how data moves, how transactions happen, how privacy is respected. The lesson from GDPR, from IAB Tech Lab, from the cookie deprecation saga: trust is the precondition for everything else.”
The meta-lesson from running the industry's standards body.

Justin Cooke Why Snowflake?
Dennis Buchheim Data and AI, with basically no hyperbole, is the foundation of everything for the foreseeable X years. Snowflake is the data cloud. After 20-plus years touching every layer of the ad tech stack, the foundation is where it all converges. It fits like a glove.
