StackBack

StackBack is a mobile + browser extension app that automatically finds and applies the best stackable savings for an online purchase: card-linked offers, portal cashback, coupon codes, and loyalty points. Users connect their cards and major loyalty accounts, then shop normally. At checkout (or before), StackBack recommends the highest expected net return and guides the user to the right path (e.g., which portal to click through, which card to use, which offer to activate). It also tracks pending cashback, flags missing rewards, and generates one-tap claim templates when merchants “forget.” This is a combination traditional + AI app: AI is used to predict stackability, detect exclusions in offer terms, and estimate real payout likelihood based on historical data. The goal is simple: stop leaving money on the table without turning savings into a second job.
