Product-based referral rewards don't motivate users
Sometimes people just want money. PayPal gave $20 per referral and grew to $46B.
When to use
Your current referral program underperforms and your product benefits aren't universally compelling.
Hypothesis template
If we give [cash amount] for referrals instead of [product credit], referrals will increase because cash is universally valuable.
Method
The problem: "Refer a friend and get 1 month free!" Users don't care.
They're not sure they'll use it. They don't refer.
What PayPal did: $20 cash. To you. To your friend. Real money, real
motivation. They spent $60M and got a $46.6B company.
Why cash works:
- Everyone wants cash
- No conditions ("only valid for...")
- Feels generous
- Easy to explain to friends
- Creates urgency (free money!)
When cash beats product credits:
- Your product value isn't universally obvious
- Users might not need more of what you offer
- You want to appeal to price-conscious segments
- Quick wins matter more than long-term engagement
How to do it:
- Set a cash reward you can afford (look at CAC, cash referral should be cheaper)
- Require friend to complete meaningful action (signup, first purchase)
- Pay quickly (slow payment kills trust)
- Make it easy to claim (PayPal, bank transfer)
- Consider both-sided cash rewards
Warning: Cash can attract low-quality referrals. Require meaningful activation from referred users.
