PayPal cash-in-account network bootstrap
Use direct account credit to bootstrap a payments network when paid acquisition is more expensive than paying users to try the product.
Why this can grow a startup
PayPal’s early referral move was blunt: give people money inside the product. Stanford eCorner summarizes the logic as the founders deciding that giving each customer money for opening an account was cheaper than other acquisition options. For a payments network, the reward also taught the behavior. The user did not receive an abstract coupon; they received spendable balance inside PayPal, which made the account feel alive and gave them a reason to send money. This is expensive and easy to abuse, so it only fits products where activation, trust, and network density are worth more than the credit burned.
Company example
PayPal used sign-up and referral cash incentives in the early online-payments market after concluding that direct customer payments were the cheapest acquisition route.
