Julian Shapiro

Julian Shapiro is founder of Demand Curve (YC), former VP of marketing at Webflow, and investor at Hyper. He publishes growth and writing handbooks at julian.com, covering acquisition, retention, and content strategy. Known for distilling practitioner experience into structured taxonomies: the Product-Led Acquisition framework, the state-building retention typology, and the Creativity Faucet model.

Key ideas

• Product-Led Acquisition. Growth through natural product use — settling debts, inviting to critical conversations, billboarding, and user-generated content. Each category compounds rather than degrades because the distribution mechanism is the product itself.
• State-building retention. Four types of non-transferable asset — reputation, audience, social graph, embedded infrastructure — that accrue switching costs over time without requiring product improvement.
• Novelty as the atomic unit of writing quality. Writing quality = novelty × resonance. Novelty requires new + significant + non-obvious; resonance is the storytelling power that makes ideas land.
• Creativity Faucet. Creativity is a backed-up pipe; the first output is wastewater. Flushing bad ideas consistently is the discipline that eventually produces good ones.
