How to Build a Marketplace Web App — if you're reading this, you're likely building a budget or writing a PRD. This guide focuses on execution steps, not motivational fluff.

90-Day Execution Map

Month 1: scope + build. Month 2: launch + measure. Month 3: iterate on retention data.

Week 1–2: PRD + design
Week 3–5: development
Week 6: launch + first 100 users

Scope Discipline

MoSCoW prioritization prevents the #1 MVP failure: shipping too much too late.

Must: one job-to-be-done
Should: onboarding polish
Could: referrals, AI
Won't (v1): enterprise features
