The 7 distinct types of product virality (aka how your product can spread): 1. Online WOM: Learning about products through mentions on social media (e.g. @joinClubhouse) 2. Offline WOM: Learning about products while talking to friends or colleagues (e.g. @Airbnb) Read on 🧵 t.co/FNGHbS4I1Q

3. Incentivized invites: Get a reward for sharing (e.g. @PinduoduoInc) 4. Utility-based invites: Accomplish something ad-hoc with a friend/colleague (e.g. @Calendly) 5. Collaboration/socializing-based invites: Communicate with friends/colleagues (e.g. @WhatsApp, @figmadesign)

6. Passively experience the product: Notice the product as you go about your day or spend time with friends (e.g. @CitizenApp) 7. Actively experience the product: Get sent a piece of content from your friends, which leads you to the product (e.g. @tiktok_us)
