Evangelists, Not Mascots: Why AdTech CEOs Are Failing at Marketing — and How to Fix it with Joe Zappa

AdTech has built some of the most sophisticated technology in the digital economy — and some of the most forgettable marketing.In this episode of Signal & Noise, we sit down with Joe Zappa, Founder & CEO of Sharp Pen Media, to unpack a hard truth the industry rarely confronts:You can’t outsource belief.For decades, AdTech companies have treated marketing as something downstream — polish it, package it, delegate it. But Joe argues that’s exactly where things go wrong. When CEOs hide behind feature lists, jargon, and generic positioning, marketing becomes interchangeable. And in a crowded ecosystem where everyone claims better targeting, better measurement, and better AI, invisibility becomes the real risk.Joe makes the case that the CEO must be the chief evangelist — not a mascot, not a quote-approver, but an active communicator who can clearly articulate:What’s broken in the industryWhat they believe about the futureWhy their company existsAnd why anyone should careWe go deep on:Why AdTech messaging collapses into samenessThe difference between product speak and narrativeHow to build a simple, usable messaging “Bible”Why controversy is often safer than invisibilityThe collapse of institutional gatekeepers — and what that means for foundersHow AI can amplify clarity — or create “slop cannons”Why humanities training may be more valuable than ever in the AI eraThis conversation isn’t just about marketing tactics. It’s about leadership, conviction, and attention in a world where distribution is democratized and authenticity matters more than ever.If you’re a founder, CEO, CMO, product leader, or operator in AdTech, MarTech, or media — this episode will challenge how you think about voice, visibility, and responsibility. Because in 2026, you don’t win by having the best deck. You win by having the clearest belief.
