A popular app is not yet a business model

The peer-to-peer payments app has the users, the habit and the brand recognition. What it has never had is a revenue line that matches its popularity, because most of what people use it for is free.

Where the money could come from

Instant transfers carry a fee, and people pay it. Debit cards linked to the balance earn interchange. Merchant payments inside the app earn more. Each of those is real, and each depends on nudging free users toward paid behaviour without making them feel charged for something that used to cost nothing.

That balance is harder than it looks. Social payments are a habit precisely because they are frictionless.

What I'm watching

• Revenue per active account in the app
• Merchant acceptance of the app as a payment method
• Balances left in the app, which fund the card and the interchange

Where I stand

Flat. The asset is valuable and the monetisation is still a set of possibilities rather than a trajectory.

What would change my mind

Revenue per account rising steadily without active users falling. That would show the model can charge without breaking the habit, which is the whole question.
