Re: what this is, and isn’t

This is Principles of Marketing packed into four rounds. You’ll do the work a founder does in their first ninety days: pick a market, name a brand, set a price, write a campaign. No spreadsheets to build. No elasticity curves to model. Just the calls — and the consequences of how they fit together.

The thing being graded is not how clever any single move is. It’s whether the whole plan sounds like it came from the same brand. We call this coherence, and the engine that scores you is built around it. A premium price on a value-led buyer is a contradiction. A Hero archetype that runs discount promotions every round is a contradiction. Caregiver brand voice with influencer-heavy spend is a contradiction. The simulation will catch every one of them, every round.

Two things to internalize before you make a decision. First: Round 1 locks in what coherence means for everything after. The customer segment and product category you choose in Round 1 are the standard every later round is measured against. Choose carefully — you live with it. Second: same segments, different names. The four customer segments are the same across snacks, sneakers, and skincare. Each category gives them category-specific persona names, but the buying logic doesn’t change. Learn the four segments and you learn every category.

Read on. Then build something that hangs together.
