Consumers rely on generic blog recommendations that do not account for individual spending patterns. The result? You leave hundreds of dollars in rewards on the table every single year.

BUSINESS PLAN

The Blueprint

REVENUE MODEL

Free for consumers. Revenue comes from affiliate commissions paid by credit card issuers for each approved referral ($50 to $200+ per application). The service creates a frictionless funnel from personalized recommendation to affiliate click-through.

GO-TO-MARKET STRATEGY

Launch with social ads showing a simple hook: "You left $600 on the table last year." Drive users to a free sign-up where they link their bank account and instantly see potential savings. Viral sharing is built in as users share their savings gap on social media.

COMPETITIVE ADVANTAGE

Unlike The Points Guy or NerdWallet, which offer static editorial recommendations, CardShark delivers dynamic, personalized advice based on actual transaction data. The longer a user stays connected, the more accurate recommendations become, creating a sticky data moat.
