Summary

Data-driven analysis of how 40+ consumer apps acquired their earliest users. Just 7 strategies account for ALL early growth. Most apps used exactly one. No app used more than three. Every strategy is a form of “doing things that don’t scale” — direct engagement, not paid channels. Includes first-hand accounts from Tinder, Uber, Dropbox, Facebook, Instagram, Slack, Airbnb, and many more.
