Airbnb grew 900% YoY for 1st-time bookings.
@elonmuskc says one customer should generate three.

1. Coinbase
Refer a friend and when they purchase $100 in Crypto, you both get $10 in Bitcoin.
Like most referral programs, it's two-sided.

2. PayPal
The OG referral program.
When PayPal was starting out, they gave money away to new users and referred users.
It worked so well they had to reduce the amount of money they gave away.
At, first PayPal gave you $20 for signing up. And $20 to anyone you referred.

They then dropped it to $10.
Still, very successful, but then dropped it down again to $5.
According to @elonmusk, PayPal spent roughly $60m on their referral incentives.
For PayPal, the daily growth rate was 7 - 10%. Plus, the user base surpassed 100m users.

Musk compared it to bacteria in a Petri dish.
Your referral program needs to expand quickly, and it has to happen fast.
Free money makes that happen.

4. DropBox
DropBox followed in the footsteps of PayPal.

- Refer a friend and you get 500MB of free storage.
- Your friend gets 500MB of free storage

4. Airbnb
Getting paid to travel? Imagine that.
Airbnb made it happen.
They launched V 1.0 of their referral program in 2011.
How it worked:
- Refer a friend, and you’ll receive $25 when they take a trip
- Refer a friend, and you’ll receive $75 when they rent out their place

After seeing the success, they scratched V 1.0 and launched V 2.0.
Version 2.0 focused on distribution and driving awareness to their referral program.
They added things like:
- Direct invites via email
- Importing contacts
- Header to their site

A survey showed that Prime Members:
- Spent 2x as much as non-Prime members
- They also order more frequently than non-prime members

6. Google
Of course, why would the most visited site in the world not have a referral program?
A badass one at that.
Their goal was to drive users to their Google Apps.
So, Google created 3 easy to navigate panels to tell you how to partake.

Here’s how it worked:
- For every user who signed up through your referral link, you would get $20
- You can do this until you reach $2000
Plus, a few days later, you’d receive an additional 20% off for the first year of Google Apps.
