You and your friends already spend money every day on groceries, subscriptions, travel, coffee, and more.
What if that everyday spending helped you earn rewards?
With KAST referrals, every eligible friend you bring in can help put rewards back in your pocket. This May, KAST is adding more ways to earn through referrals, milestone bonuses, Premium access, and social rewards.
How it works
Three steps. One path. No complicated rules.
- Share your referral link from the KAST app.
- Your friend signs up, completes verification, and activates their card.
- Your friend spends. Once they hit $100 in total spend, your referral counts and you earn up to $250.
- When a referred friend reaches $500 in spend, they become a qualified referral, unlocking bigger milestone rewards starting at 5 friends.
The more qualified friends you refer, the bigger the rewards.
| Friends referred | What you unlock |
|---|---|
| 1 friend | Up to $250 in referral rewards |
| 5 friends, each spending $500+ | +$100 milestone bonus on top of your per-friend rewards |
| 10 friends, each spending $500+ | 6 months of KAST Premium, excluding the physical metal card |
Eligible rewards can stack. Refer 10 friends and you could earn up to $2,500 in referral rewards, $200 in milestone bonuses, and 6 months of KAST Premium, excluding the physical metal card.
The Premium unlock
This is the big one. Refer 10 friends who each spend at least $500, and you get 6 months of KAST Premium for free.
You get boosted cashback rates and Premium benefits, with the physical metal card excluded.
No subscription fee. No upgrade purchase. You earn your way in.
Spots are limited to the first 10 people who hit this milestone.
Show your wins, earn more
Share your referral earnings or cashback rewards on X, Instagram, or TikTok with #KASTCashback and/or #KASTReferrals for a chance to win weekly prizes:
