NYC is structurally the best U.S. city for marketplace startups. Density + demand diversity + supply niches = faster liquidity.

• Kickstarter — crowdfunding.
• Vroom — car marketplace (struggled post-2022).

Why NYC marketplaces work

1. Density: 8M+ people in ~300 square miles generates liquidity.
2. Diversity of supply: Niche categories reach minimum viable supply faster.

4. Media proximity: Launch PR amplifies bootstrapped marketplace growth.

• StockX (Detroit but NYC-active).
• Vrbo, Airbnb (broader U.S. but NYC dense).

What NYC VCs look for in marketplaces

1. Liquidity at the category/geography level: Time-to-liquidity in initial market.
2. Take rate + retention: Healthy, growing, non-extractive.
