The model begins with a free or subsidized consumer utility that creates frequent exchanges and aggregates demand. Instead of taxing those social interactions, the platform encourages money or value to remain inside its network, reducing external settlement costs. Once the consumer side is sufficiently large and active, the company recruits merchants that want access to that demand and charges them for acceptance, distribution, or transactions. This converts a costly peer-to-peer product into the acquisition layer of a commercial payment network. The mechanism depends on density: consumers must use the product often enough that merchants benefit from joining, while merchant acceptance makes stored balances more useful and further reduces the need to cash out.
Origin
Venmo's founders planned from the beginning to use peer-to-peer payments to grow the consumer side before monetizing merchants, a strategy later enabled by Braintree and PayPal.
Core principles
- 01Use free peer activity to build the demand side
- 02Keep value inside the network whenever possible
- 03Monetize the commercial side rather than ordinary social exchange
- 04Delay merchant expansion until consumer adoption creates leverage
- 05Connect both sides through a shared balance and payment layer
How to run it
- 1
Choose the Free Side
Identify the participant group whose adoption creates network leverage but whose willingness to pay is low. Give that side a compelling utility with minimal friction.
Pro tip Choose a behavior users already perform frequently outside the product.
Watch out A free product without recurring utility will not create meaningful leverage.
- 2
Build Transaction Density
Increase the frequency and number of relationships within the consumer network. Make each additional participant improve the usefulness of the product.
Pro tip Design transactions that naturally invite or notify another participant.
Watch out Raw registrations matter less than active connections and repeated transactions.
- 3
Retain Value in the Network
Make balances immediately reusable so participants do not need to settle every transaction through an external bank.
Pro tip Add convenient spending and transfer options without making withdrawal feel punitive.
Watch out Holding balances requires careful regulatory and trust management.
- 4
Recruit the Paying Side
Approach merchants once the consumer network offers meaningful reach, conversion, or reduced payment friction.
Pro tip Start with merchants already popular among the active consumer cohort.
Watch out Premature merchant sales can consume resources before the network has leverage.
- 5
Monetize Acceptance
Charge merchants for transactions or access while keeping ordinary peer exchange inexpensive. Use the resulting acceptance to make consumer balances more useful.
Pro tip Integrate directly into checkout as well as through a broadly accepted card or payment credential.
Watch out Excessive merchant fees can prevent the second side from reaching critical mass.
In the wild
Venmo grew a consumer payment network without planning to monetize peer-to-peer transfers. Under PayPal, it could connect those users to an existing merchant network and introduce Pay with Venmo and the Venmo card, creating commercial transactions from previously unmonetized balances.
→ The consumer network became a potential demand and payment layer for millions of merchants.
Common mistakes
Charging the Free Side Too Early
Fees on ordinary peer exchanges weaken adoption while competing against cash and bank transfers.
Building Two Sides Simultaneously
Trying to recruit merchants before consumer demand is dense can create an expensive sales effort with little merchant value.
Counting Volume Without Liquidity
Large transaction volume is less valuable when every payment immediately exits the network and incurs settlement costs.
Is it for you?
Best for
It is best for payment systems and marketplaces where a free consumer utility can aggregate demand valuable to merchants.
Not ideal for
It is not ideal when users transact too rarely, merchants have no willingness to pay, or the two sides cannot share one network.
From the transcript
“we knew there was no business of P2P transactions”
“It was all just the grow that side of the network, and then once you have leverage, go get the merchants onto the um network…”
“you charge businesses to accept payments from people that have Venmo.”
