From Zero to 1000 customers in 20 weeks - YC 12 Rules

Origami went from zero to over a thousand paid customers in twenty weeks, without a single growth hack or paid ad. The playbook: twelve Y Combinator rules, followed religiously across four chapters. Co-founder Finn Mallory shared the whole thing — a two-person team, code shipped every Friday, and three hours a day of the CEO on user calls. ### Chapter 1 — Foundations: earn the right to grow Before spending a dollar on growth, earn it. The rules here: 1. Grow retention first — Origami set a 90% weekly retention gate before running a single growth campaign. 2. Ignore everyone who isn't a customer — no vanity signals, no advice from non-users. 3. Manual beats premature automation — hand-crank the work until the shape of it is clear. ### Chapter 2 — Build with customers: payment is the only validation Origami put a credit-card gate on day two, shipped a barely-working version to thirty users in week one, and let user calls write the roadmap. Three hours a day, every day, the CEO on calls — not a launch stunt, the permanent operating system. ### Chapter 3 — Discipline: consistency compounds - Fire bad-fit customers early. - Ship to production every Friday as a heartbeat, not a goal. - Stay small far longer than feels comfortable. The line that captures it: ten people who love you beat a thousand who kind of like you. ### Chapter 4 — Survival: startups die of time, not markets Default alive gets tracked on a whiteboard every week. Three near-death moments count as baseline. Brutal honesty between co-founders is the cheapest insurance you'll ever buy. The whole playbook fits on one screen — twelve rules worth re-reading every week rather than agreeing with once. None of it works once; all of it compounds.
