Earn more from the cards already in your wallet.
A consumer product that optimizes credit-card rewards — the right card for every purchase, without thinking about it.
Most people lose money on every swipe — and never notice.
The average wallet holds several cards, each with different rewards across categories that shift every quarter. Optimizing it by hand is a spreadsheet problem nobody wants. So people default to one card and quietly leave real money on the table, month after month.
The right card, automatically.
