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.

Core Principles

Nail the Value Exchange First

Benjamin Lauzier: "If you don't have product market fit, and if you don't have a good enough growth strategy for at least one side of your marketplace, just forget about all this marketplace stuff. Focus on this core exchange of value, go deep with one side of the marketplace and see if you can rely on some crutch, some hack for the other side for time being."

Before focusing on complex economic ratios, ensure the core transaction provides enough value to both sides to sustain a growth strategy. Identify the most difficult side of the market to acquire and concentrate early resources there.
