Build & grow
Product & Startup glossary
Startup vocabulary only helps when it connects to decisions: what to ship first, when to scale ads, and how you know users want the product. This cluster covers MVP, product-market fit, problem-solution fit, jobs to be done, and metrics indie mobile teams actually use.
Short cards define terms for docs and SEO context. In-depth guides go deeper on validation and growth signals — with quoted notes from Sych on shipping multiple consumer apps, not accelerator slide decks.
Pair these pages with analytics and monetization glossary entries when you move from validation to pricing and paywall experiments.
