A blunt, practical guide from Demand Curve's founder on which paid and organic channels fit which business, and why most startups can't profitably buy ads early on.
Shapiro gives you a concrete framework you can apply the same afternoon: write a header that is fully descriptive of what you sell, then build your value prop from a bad alternative, a better solution, and an action statement. It is free, example-heavy, and written for founders drafting their own page, not for agencies. Read it with your own headline open in another tab and rewrite as you go.
Julian Shapiro argues that growth should be designed into the product itself rather than bolted on afterward, so every new feature is an opportunity to build in a reason for people to notice it and share it. Read it next to your short answer, since it explains why a new integration or segment isn't just a product change, it's a fresh acquisition surface if you treat it that way.
Julian Shapiro's growth handbook frames brand and messaging as downstream of who you're for and what you replace, practical foundations, not brand theory.
Julian Shapiro's handbook makes the growth marketer's case for a narrow ICP: going broad invites a competitor to pick off your best customers by serving a narrower slice better than you do. It is written for founders also thinking about acquisition channels, so it connects customer definition directly to where and how you will find them. A quick, dense read with none of the usual marketing fluff.
Shapiro's method, asking 100 people representative of your guessed audience whether they'd put down a cash deposit, is a fast, concrete way to test a narrow ICP hypothesis before you build. It forces you to define the audience precisely enough to actually go find 100 of them, which is half the exercise. Good for founders who keep testing their idea on friends instead of strangers who match the profile.
