Welcome to the Marketing Systems Guild. Before you do anything else, go through the Start Here module in the Classroom tab. It takes about 15 minutes and covers everything you need to know — what mental models are, why they matter, how this community works, and how to get the most out of it. 👉 Start tere course Once you've finished, come back here and introduce yourself: 1. What's your role? 2. What's the biggest marketing question you're wrestling with right now? That's it. See you inside.

I spent over 20 years in marketing — B2B, B2C, insurance, fintech, retail — and the pattern I kept seeing was the same everywhere. Smart marketers. Working hard. Running campaigns. Hitting KPIs. And still feeling like they were stuck on a treadmill. The problem was never effort. It was thinking. Most of us learned marketing by doing — which is great until you realize you're executing without a framework for why. We optimize campaigns without understanding customer psychology. We track metrics without asking if they connect to anything that matters. We call things "strategy" when they're really just a list of tactics. I started studying mental models because I needed better answers for myself. First principles thinking. Jobs-to-be-done. Value creation. Customer economics. How markets actually move. What measurement should actually do. And the more I applied these models, the more everything changed. Not just the results — the way I thought about the work. The questions I asked. The things I said no to. That's what this community is about. The Marketing Systems Guild exists for one reason: to help in-house marketers think better. Not more frameworks to memorize. Not another course to sit through. A place where we practice strategic thinking together — on real problems, with real stakes. Here's what I believe: → Better thinking leads to better marketing → Mental models are skills, not theories → The best marketers question everything, including their own assumptions → We get sharper by thinking out loud with other sharp people If that resonates, you're in the right place. I'll go first: I'm Bill. I build marketing systems that compound. I've spent my career trying to connect customer economics to strategy to execution — and I'm still learning how to do it better.
