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.
Source-backed 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.

When to use it
Use this when Referral, Fintech, Network Effects is relevant to network bootstrap, cash incentive, fintech and you can run a bounded test with a high budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to Referral and Fintech, using evidence from Stanford eCorner: Selling Customers - Getting the Product Out as context—not as a promised result.
- Record a baseline for: Share of target users completing the product's first-value action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
