Marketing Over Coffee · [email protected] (John Wall and Christopher Penn)

Tales of Economic Fear, TAM, Twitch and Smart Glasses!

Why are marketers ignoring AI for legal paper review when it's one of its strongest applications?

The opener starts in Canada. Christopher Penn has just returned from Edmonton, where a tourism industry event focused on generative AI, tariffs, and trade wars. The anxiety feels specific, not abstract. He describes a turn toward Canada-first buying, including the blunt detail that Kentucky bourbon purchasing had dropped to zero. Then the AI thread picks up. Open models such as DeepSeek come up as part of the business response, since organizations and countries may want less dependence on the USA. John Wall then pulls the conversation toward TAM, SAM, and serviceable market math, asking whether those numbers are actually useful. Penn's answer is practical: a lot of startup market sizing is guesswork, especially when the pitch quietly assumes everyone is a buyer. Better research tools exist now. He points to Google Gemini, Perplexity, and OpenAI as ways to find sources and test whether a product has a real addressable market. The awkward part is that the answer may be no. A tool might show that the product does not solve a real problem, or that the market is already handled. AI agents become the warning label. Penn uses an SEO agent example to show how work already covered by SEMrush, Ahrefs, and Moz can be rebuilt in a pricier, shakier form. The possible market may look huge. The real serviceable market for a worse version may be no one. The close shifts back to travel, with Social Media Marketing World, a long April on the road, gear talk, and travel hacks.
