Transaction-as-distribution network effect
Design your product so that every core user action (like sending a payment, sharing a doc, or hiring a contractor) automatically exposes the product to a new potential user.
Why this can grow a startup
Unlike bolted-on referral programs, embedding distribution into the core transaction makes growth inseparable from product usage. Every new customer automatically generates qualified exposure to their counterparts. This creates a self-reinforcing loop where growth accelerates with usage volume, not marketing spend. Deel's model proved this scales globally across geographies and industries.
Company example
Deel — grew from an early-stage HR tech startup to a $12B valuation by making every global hire a viral node; each employer-contractor transaction introduced Deel to a new user on the other side.

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.
Founder checklist
- Read medium.com and identify what is directly supported.
- Choose one channel context: Referrals.
