AdTech is shifting faster than ever – privacy, AI, and platform fragmentation are rewriting the rules in real time. My focus? Cutting through the noise to make sense of it all, independent, unapologetic, pragmatic, and solution-oriented. With over a decade in programmatic and digital media — and Ex’s from every corner of the ecosystem (Big Tech, agency holding companies, Fortune 500 brand) — I’ve seen the game from all sides. Now I do things my way. No titles. No KPIs. No decks. Just research, writing, frameworks and a relentless curiosity to figure out where this industry is really going. Think of it as my self-directed PhD in AdTech: one post, one article, one rabbit hole at a time.

We’re still in the early days of AI and even more so when it comes to AI-filtered recommendations and advertising. You’re absolutely right that things are far from ideal right now. But to be fair, digital advertising has always been shaped by gatekeepers: search algorithms, social feeds, and now AI-powered assistants, predictive models, curated experiences, you name it. The crucial part, the human part, is keeping us in the loop. Because if we want people to feel seen, understood, and inspired, we can’t hand everything over to machines. It’s worrying how fast the focus is shifting to AI...and how easily we forget ourselves in the process.
