Monetize by making your dApp token-gated. Users no longer have to use credit cards or manage OAuth credentials. Rather, they buy & spend ERC20 datatokens to access your dApp content.
Go further yet: rather than storing user profile data on your centralized server -- which exposes you to liability -- have it on-chain encrypted by the user's wallet, and just-in-time decrypt for the app.
You can do this by [forking Ocean Market code](../developers/build-a-marketplace/) to quickly get something good, or by building up from Ocean components for a more custom look.
