Marketplaces are among the most valuable business models—think Airbnb, Uber, and Grab. But they're also among the hardest to build. Here's what you need to know.
What Makes Marketplaces Different
Unlike traditional businesses, marketplaces must serve two distinct customer groups:
- Supply Side: Sellers, providers, drivers, hosts
- Demand Side: Buyers, consumers, riders, guests
Success requires creating value for both sides simultaneously.
The Chicken-and-Egg Problem
The classic marketplace challenge: buyers want sellers, sellers want buyers. How do you start?
Strategy 1: Seed the Supply
- Manually onboard initial providers
- Offer incentives (reduced fees, guaranteed income)
- Create supply yourself initially
Strategy 2: Start Single-Player
- Build tools that provide value to one side alone
- Then connect them to the other side
- Example: OpenTable started with restaurant booking software
Strategy 3: Narrow Focus
- Start with a specific niche or geography
- Achieve critical mass in one segment
- Then expand methodically
Marketplace Types

3. Rental/Sharing

Monetization Strategies
Transaction Fees
Most common model—take a percentage of each transaction:
- Typical range: 5-25% depending on industry
- Can charge buyer, seller, or both
- Lower fees for higher-value transactions
Subscription/Membership
- Monthly fee for premium features
- Works well for frequent users
- Provides predictable revenue
Featured Listings/Ads
- Charge sellers for visibility
- Promoted placements in search
- Display advertising
Key Metrics to Track
- GMV: Total transaction value
- Take Rate: Revenue / GMV
- Liquidity: % of listings that transact
- Time to Transaction: How fast buyers find sellers
- Repeat Rate: % of users who transact again
- NPS: Net Promoter Score for both sides
