What it means
A marketplace can connect buyers with independent sellers, helping them find each other, assess trust and complete an exchange, so its core product is often the interaction. Deloitte explains that a platform business model is not just a technology stack but facilitates interactions among participants and can be digital or physical, and an auction house illustrates the idea without needing an app.
A traditional retailer buys goods and resells them whereas a marketplace may let third parties list goods, though some platforms also hold inventory, so the distinction is about who creates and delivers value under the actual model. A fictional freelance platform connects businesses with designers, offering profiles, proposals, payments and dispute handling, but without credible work and customers on both sides the software alone has little value.
Andreessen Horowitz defines marketplaces as platforms connecting buyers and sellers with transaction support and notes that real models can also hold inventory or employ providers, so do not assume every platform is asset-light. Platforms can also have more than two participant groups, as a food-delivery service may coordinate restaurants, couriers and diners, and each group needs a reason to participate and clear rules.
A platform may earn a percentage of transactions, a fixed listing fee, subscriptions or advertising, and these sources have different incentives, so a fee that discourages suitable matches can undermine the service. A fictional property portal that charges agents for listings earns revenue from the listing service and not necessarily a percentage of home sale value, so gross merchandise value is not the right revenue formula for every platform.
For a transaction-fee model, revenue relates to transaction volume and the agreed take rate, so if $5 million of eligible transactions carry a 12% fee the simple fee amount is $600,000 before refunds, incentives and accounting differences, which is why the volume basis must be defined. Network effects may help, since more relevant participants can improve value for others, but more users are not automatically better because poor-quality listings or congestion can make a platform harder to use.
Liquidity matters in a marketplace, as buyers should find suitable offers and sellers should find real customers within a useful time, and a large registration count without matches is weak evidence of value. A fictional repair marketplace that expands to ten cities with few technicians in each leaves customers facing long waits, so it concentrates supply and demand in a smaller area before expanding again.
Trust mechanisms can include identity checks, reviews, payment protection and clear dispute processes, with scope varying by the risk of the interaction, and a platform that promises checks should actually perform them. Rules on ranking, fees, data and removal affect participants, so document governance and handle complaints fairly.
A platform can also support collaboration or learning rather than a purchase, since Deloitte describes social, mobilisation and learning platforms alongside transaction-focused ones, and a fictional industry forum whose member firms share knowledge under common standards can fund moderation from subscription fees with no gross sales at all. Scaling is not free, because customer support, fraud prevention, technology, compliance and payments can grow with activity, so avoid claiming a platform can expand without operational investment.
If the platform collects money on behalf of providers, accounting may distinguish gross transaction value from its own revenue, so review who controls the service and bears obligations, since the whole customer payment is not always platform income. A successful model aligns incentives among participants because low-quality supply can drive buyers away and unfair terms can drive good suppliers away, so test actual participant value, governance and economics before assuming the model has a durable advantage.
In practice
Real-world examples.
Example
A freelance platform matches businesses with independent designers and holds the payment until work is approved. It earns a fee on each completed project. Its value depends on enough credible designers and enough clients being present at the same time.
Example
A food-delivery service coordinates restaurants, couriers and diners in the same city. Each group needs a reason to take part, and the service must manage delivery times and complaints. A weakness on any one side, such as too few couriers, harms the other two.
Example
An industry forum earns subscriptions by supporting knowledge exchange among member firms. No goods are sold through it, yet it still has to moderate content and enforce common standards. Its value is measured by useful exchanges rather than by gross sales.
Formula
Calculation
For a transaction-fee model only, illustrative fee income = eligible transaction value x agreed take rate, adjusted for refunds and contract terms. Other platform models use other revenue bases.
Worked example for an invented marketplace. Customers pay $5,000,000 for jobs in a year and the platform charges providers a 12% take rate.
- Fee income before adjustments = $5,000,000 x 12% = $600,000.
- If $50,000 of jobs are refunded, eligible value = $5,000,000 - $50,000 = $4,950,000 and fee income = $4,950,000 x 12% = $594,000.
- Providers receive the remainder: $4,950,000 - $594,000 = $4,356,000.
- Only the $594,000 is the platform's own revenue if it acts as an agent. Reporting the full $5,000,000 as revenue would overstate the business.Case study
Seen in the real world.
In this fictional example, HandyHarbor lets independent technicians offer home repairs. It builds profiles and payment tools but initially lacks enough technicians in each district. The company focuses on two districts, checks completed matches and improves quality controls. It does not infer success from account signups alone.
Watch out
Common mistakes.
- Assuming every platform has no inventory or operating costs.
- Counting users without checking useful interactions.
- Treating total transaction value as the platform's own revenue.
Questions
People also ask.
Must a platform be digital?
No. Digital tools can help, but the model is about facilitating interactions.
How does it make money?
Fees, subscriptions, ads or other terms depending on the service.
Are network effects guaranteed?
No. Relevant, reliable participation must actually improve value.
