I read business books, study companies, and write analytical case studies that extract the frameworks, patterns, and lessons that matter—cost structures, capital allocation, competitive advantage, and industry evolution.

How a trucking company escaped commoditization by partnering with railroads to pioneer intermodal freight—and built a $16.5 billion business with a 14% ROIC in an industry most dismiss as a commodity.
Costco never raises prices—it attacks its own cost structure instead, passing 89% of every cost reduction to its 137 million members. A study in how many small advantages compound into an unassailable position.
One company clung to high margins while its market changed beneath it; the other adapted repeatedly. A comparative study of how Circuit City’s margin obsession became its undoing while Best Buy read the customer.
I’m Anton Zitz. I’ve worked in investment banking, middle market private equity, corporate development, and consulting. I write these case studies because the best business thinking shouldn’t be locked inside 300-page books most people never finish—or if they do, struggle to apply.
Each study is built around a recurring concept: cost structures, capital allocation, scale economies, the margin trap, or industry evolution. They’re designed to be analytical tools, not book reports.
