Two-sided referral reward
Offer both the inviter and the invitee a meaningful reward so sharing feels generous rather than transactional.
Why this can grow a startup
It turns users into a distribution channel by aligning incentives on both sides of the invite.

When to use it
Use this when Referrals is relevant to 0-100, 100-1K and you can run a bounded test with a free 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 Referrals, using evidence from dropbox.com as context—not as a promised result.
- Record a baseline for: Share of referred users who reach the activation milestone. 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.
