How to Price a Two-Sided Marketplace: The Decision Every Founder Gets Wrong

Pricing is the decision most marketplace founders make once, early, and almost never revisit with enough rigour. It gets set in the excitement of building, never quite challenged, and then defended long after it stops making sense.

But pricing in a two-sided market is not a single decision. It is at least four separate decisions that interact with each other in ways that are easy to get catastrophically wrong. Here is how I approach it with clients, and what I have learned from watching founders make the same mistakes across 30+ builds.

The four pricing decisions in a marketplace

1. Who pays?

The first question is not how much to charge — it is which side of the market to charge at all. In many successful marketplaces, one side is free. Craigslist charges sellers for certain categories and buyers nothing. OpenTable charged restaurants, not diners. Airbnb charges both sides, but the split has shifted over time.

The rule of thumb: charge the side that is harder to acquire and less price-sensitive. If getting sellers onto your platform is the hard problem, consider whether making it free to list accelerates your supply side enough to justify the foregone revenue. If buyers are the constrained side, consider whether a buyer fee creates friction that kills conversion.

Most early-stage marketplaces should not be charging both sides. You are not Airbnb. You do not have the network density to make both sides accept a fee. Pick the side you can monetise and keep the other side frictionless.

2. What model — take rate, subscription, listing fee, or freemium?

The most common model is a take rate: you charge a percentage of every transaction. It aligns your incentives with your marketplace (you only earn when transactions happen) and it scales with GMV. This is the right model for most transactional marketplaces.

But it is not right for every situation:

• Subscription works when suppliers derive ongoing value from being listed regardless of transaction volume — professional directories, SaaS-adjacent platforms, or marketplaces where discovery is the primary value delivered.
• Listing fees work in high-volume, low-value transaction markets where a take rate would be too small to be meaningful — classifieds, job boards, some B2B categories.
• Freemium works when you can offer genuine free value that creates habit, then layer paid features on top of an engaged user base. It requires significant volume before it generates meaningful revenue.

The worst outcome is choosing a model because it sounds good, not because it matches how your users actually get value. I have seen subscription marketplaces where sellers resent paying monthly when transactions are scarce, and take-rate marketplaces where the percentage is so low it cannot sustain the business.

3. How much?

Take rates in successful marketplaces range from 3% (logistics, payments-adjacent) to 30%+ (Airbnb in some markets, App Store). The right number depends on three things:

• Your value delivery. What do you actually provide that justifies the fee? Discovery, trust, payment infrastructure, dispute resolution, marketing? The more genuine value you add beyond the transaction, the more defensible a higher take rate is.
• Competitive alternatives. If sellers can easily reach buyers through other channels at a lower cost, you have a ceiling. If your platform is the only viable discovery channel in your niche, your pricing power is higher.
• Seller economics. Model what a typical seller earns per transaction, then work backwards from the fee they can absorb while remaining motivated to use your platform. A seller with a 20% margin cannot sustain a 25% take rate — they will leave or undercut you off-platform.

My general guidance for early-stage marketplaces: start lower than you think you need to, prove the transaction volume, then raise it once you have demonstrated clear value. It is much easier to raise prices on a platform people depend on than to launch at a high price point before you have earned that dependency.

4. How do you prevent disintermediation?

Disintermediation — buyers and sellers agreeing to transact off your platform to avoid your fee — is the silent killer of marketplace unit economics. It is also a direct signal that your take rate is too high relative to the value you deliver.

The solution is not to add friction that makes it hard to communicate off-platform. That approach breeds resentment and damages the user experience. The solution is to make the on-platform transaction meaningfully more valuable than the off-platform alternative.

What makes on-platform transactions more valuable? Payment protection, dispute resolution, reviews and reputation, insurance, verified identity, and liability coverage. The more of these you offer, the more users will choose to stay on-platform even when they could technically go around you.

The pricing mistake I see most often

Founders set a take rate based on what they think sounds reasonable — typically 10-15% — without modelling seller economics or testing buyer price sensitivity. Then they discover six months in that either sellers are quietly moving transactions off-platform, or their take rate is too low to cover CAC and support costs.

Pricing is not a set-and-forget decision. It should be revisited every six months with real data: what is your actual take rate (net of discounts and refunds), what is your blended CAC, and what would it take to make the unit economics work at your current growth rate?

A framework for getting started

If you are setting marketplace pricing from scratch, here is the order of operations I recommend:

1. Map the transaction: what happens, what you provide, and what each side gets.
2. Model seller economics: what margin does the seller need to remain motivated?
3. Identify competitive alternatives: what does it cost sellers to reach buyers elsewhere?
4. Choose a model (take rate is usually right for transactional marketplaces).
5. Set an initial rate that is sustainable for sellers and meaningful for your business.
6. Launch, measure disintermediation signals, and adjust.

The right price is not the highest price you can charge. It is the price at which both sides feel the platform is worth using — and come back.

Pricing in a two-sided market is ultimately about trust. Charge too much and sellers leave. Charge too little and you cannot sustain the platform that makes the market valuable. Getting this right is one of the most important product decisions you will make, and it deserves more than a quick number pulled from a competitor or a gut feeling in a founding meeting.
