THE PROBLEM

Rewards are fragmented by design.

Too many sources
Cards, portals, loyalty apps, gift cards and discount programmes all live separately.
Too many rules
Eligibility, exclusions, categories, caps and expiry dates make comparison hard.
Too late
People often discover the better option after they have already paid.
THE IDEA

Bring the decision to the moment of purchase.

Stackwise aims to become the neutral decision layer between “I want to buy this” and “I’ve paid”.

That means supporting the user first, making commercial relationships clear, and separating ranking logic from paid placement.

PRODUCT PRINCIPLES

Useful, private, explainable.

Use what the user owns

Recommendations should start from the user's real wallet and preferences.

Explain the route

Show why a recommendation wins, not just a mysterious score.

Earn trust before revenue

Commercialisation should not silently distort the answer.
