The market decides, not you
The most expensive sentence in business: “If I build it, they will come.”
The Iron Law of the Market: the market is the ceiling. A brilliant offer in a market that doesn't want it stays small; an ordinary offer in a hungry market grows. The size and hunger of the market cap everything you can earn — the market decides, not you.
Dean Kamen poured over $100 million into a brilliantly engineered personal transporter and predicted selling tens of thousands a week — enough to reshape how cities move.
→ It sold a tiny fraction of the projections and became a niche tourist-and-security product — and a punchline.
The engineering was real; the mass market at ~$5,000 for a short-range scooter simply did not exist. He fell in love with the product instead of the buyer.
Before you build or expand, confirm a large enough group urgently wants it — at a price they'll pay. Demand-first is the cheapest insurance you can buy; product-first is the most common way to lose your savings.
Personal MBA calls it the Iron Law; Lean Startup calls the fix “validated learning”; Blue Ocean says look where demand is un-served. Three books, one warning: chase the buyer, not the product.
You cannot out-execute a market that isn't there. Prove the demand before you spend — the next module shows you how, for pennies.
Ask five recent customers what they almost bought instead of you. Their answer is the shape of your real market.
