In short
A marketplace pitch deck should show how you attract both sides, buyers and sellers, gross merchandise value (GMV) and its growth, take rate, liquidity (how often a listing or request is matched) and repeat use. Explain how you solved, or will solve, the chicken-and-egg problem.
Marketplaces can become very valuable because of network effects, but they are hard to start. Investors want proof that the marketplace works in at least one niche or city before it expands.
Who invests in marketplace startups
Marketplaces are funded by generalist venture capital firms, consumer and business-to-business specialists, and angels who have built marketplaces before.

Metrics marketplace investors look for
| Metric | Why it matters |
|---|---|
| GMV | Total value transacted; shows scale. |
| Take rate and net revenue | What you keep; investors value net revenue, not GMV. |
| Liquidity | Share of listings or requests that result in a transaction. |
| Repeat rate | Shows buyers and sellers keep using the platform. |
| Supply and demand concentration | Reliance on a few large users is a risk. |
What makes a marketplace pitch deck stand out
- Strong liquidity in one niche or city before expansion.
- Repeat use without discounts.
- Trust features that reduce leakage off the platform.
- Low-cost acquisition on at least one side.
Common mistakes
- Presenting GMV as revenue.
- Growing too many cities before one works.
- Ignoring leakage, where users meet on the platform and then trade outside it.
- Discount-driven growth.
Frequently asked questions
How do I show a marketplace works before it scales?
Show liquidity, repeat use and unit economics in one well-defined niche or location. Investors would rather see a small market that works than a large one that does not.
