Referral

Turning users into a growth channel: virality, word-of-mouth, network effects, and referral loops.

Referral and virality are the levers most companies claim to have and almost none build correctly. A referral program is not a growth loop. Word of mouth is not a strategy. These posts get into the actual mechanics: k-factor math, the network effects that create a structural advantage, viral loops that are product-native instead of bolted on, and the conditions that make users refer without being bribed.

Below are teardowns of how specific products built referral into the core experience, essays on why most referral programs fail and what works instead, and frameworks for measuring whether your word-of-mouth engine is real. Filter to teardowns for company-specific breakdowns, or to playbooks when you want something executable for your own referral loop.
