The card issuers do their individual basic fraud detection (e.g. security code) but we built our own on top after users asked for something more advanced. Imagine Stripe seeing data across all the card networks, compound that with customer info (like email or IP, which card networks don’t always collect) across all businesses on Stripe, then that’s fed into our ML network that’s constantly tuned by Stripe engineers. And then businesses have the opportunity to customize all that with Radar.

True, but the big networks process far more transactions than stripe does, have access to more data (where else has this card been used lately, has the bill been paid, has this customer used the card in a shop abroad, etc), and seem in a better position overall to combat fraud.

The network also has access to the account holders phone number so can actually call to validate risky transactions.

Lower fraud rates would also make issuing banks more likely to choose visa over MasterCard, so be a competitive advantage.
