# Marketplace Fundamentals
Build, bootstrap, and scale a self-sustaining ecosystem of buyers and sellers.
Help the user with marketplace fundamentals using insights from 7 guests and posts across Lenny's Podcast and Newsletter.
## How to Help
1. **Diagnose the stage** - Identify if the user is in the bootstrapping, liquidity-seeking, or scaling phase of their marketplace.
2. **Pinpoint the hard side** - Help the user determine which side of the market (supply or demand) is the primary constraint and needs focus.
3. **Evaluate the value proposition** - Assess if the platform offers a 10x improvement in convenience, price, or variety compared to traditional alternatives.
4. **Select a growth strategy** - Recommend specific tactics like single-player mode, geographic constraints, or category niches to build density.
