What problem does it solve? Networked products like marketplaces, social apps, and collaboration tools are worthless without users, and launching to a broad market usually produces empty rooms and churn. This Skill applies Andrew Chen's Cold Start Problem framework to help you pick an atomic network, solve the hard side first, tip networks one at a time, and diagnose stalled growth. ## Core Features & Use Cases - Atomic Network Scoping: Define the smallest self-sustaining network, derive its minimum size, and write a measurable magic moment with instrumented zero states. - Hard-Side Strategy: Identify the minority of users who create most value, map their money/status/utility motivations, and design subsidies, tools, or status programs to win them first. - Tipping Playbooks & Growth Diagnosis: Plan invite-only launches, supply pre-commitment, and subsidy tapers, then diagnose which ceiling (saturation, CAC creep, quality decay, hard-side revolt) is stalling growth. - Use Case: A founder launching a home-services marketplace uses the Skill to retreat from three cities to one zip-code cluster, pre-commit 35 cleaners with published guarantee tapers, and gate expansion on fill-rate and time-to-match bars. ## Quick Start Ask the AI to evaluate your marketplace launch plan against the Cold Start Problem framework and score it from 0 to 10 with specific fixes.
