HOW IT WORKS

Three steps. One clear answer.

Add only what you already own. Stackwise handles the comparison.

1

Add your essentials

Your cards, loyalty programmes, gift cards and favourite cashback sites.

2

We find your best stack

Stackwise compares eligible discounts, rewards and cashback in the right order.

3

Shop and save

Get a clear recommendation before you pay, without juggling tabs and calculators.

THE PRODUCT

A shopping co-pilot, not another rewards dashboard.

The long-term vision is simple: Stackwise appears when it can save you money or improve your rewards, then gets out of the way.

Browser extension
Surface the best route while you shop online.
Smart wallet
Keep cards, loyalty schemes, gift cards and cashback preferences together.
Future mobile layer
Bring the same recommendation to shops, restaurants and real-world spending.
BUILT TO EXPAND

From checkout to everyday spending.

Start with high-intent online purchases. Expand into in-store, loyalty discovery, card-linked offers and partner distribution as the network grows.

Stop guessing which reward to use.

Open Stackwise and find your best route.
