Viral waiting list with queue-jumping referrals
Create a pre-launch waiting list where users can move up the queue by referring friends, turning exclusivity into viral distribution.
Why this can grow a startup
Monzo attracted 200,000 signups before launch using a waiting list that showed users their position in the queue and offered a "Bump me up" button tied to a personal referral link. The mechanic combines loss aversion (you're behind others) with a clear reward (skip ahead). Each share gives the brand free social media visibility while deepening engagement with the referrer.

When to use it
Use this when Email, Referrals is relevant to pre-launch 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.
Founder checklist
- Read targetinternet.com and identify what is directly supported.
- Choose one channel context: Email, Referrals.
- Define the test around one observable customer behavior.
- Set an owner, evidence window, and stop condition before launch.
