The situation
CPMs up, codes leaking, payouts eating ops time.

The bet
“Let fans do the talking—and automate the rest.”
Referbro added WhatsApp sharing on the Thank-You page and a persistent “Refer & earn” on the homepage. Discounts auto-applied; fraud filters on.

The offer

• Friend: 12% OFF

• Referrer: ₹175 cashback after validation

• MOV: ₹1,199

How it worked

1. Customer shares from the Thank-You page.

2. Friend lands, sees welcome, checks out with the discount auto-applied.

3. Return window closes; cashback goes out automatically.

4. Fraud checks block self-orders and abuse.

What happened in 60 days

• 3.6% of monthly orders from referrals (trending 6–8% with reminders)

• Fraud stayed <0.5%

• Finance reconciliation simplified

Why it worked
Frictionless mobile sharing, automatic rewards, and strong guardrails.
