Employee-as-viral-node network effect loop
Design your product so that every new user or customer automatically creates distribution by pulling in their own network as part of normal usage.
Why this can grow a startup
Deel engineered a growth loop where every company that hired a global employee through the platform exposed Deel to the employee, that employee's future employers, and their professional network. This self-reinforcing system helped Deel grow from a startup to a $12B valuation by 2025 without relying on traditional paid acquisition. The key insight is building distribution into the product's core workflow rather than bolting it on as a referral program.

When to use it
Use this when Partnerships, 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.
