In every successful network, a small group of users does the heavy lifting. These power users—whether content creators, sellers, or drivers—generate most of the activity and value. Wikipedia’s vast knowledge base is built by less than 0.02% of its users. Similarly, 20% of Uber drivers provide 60% of rides.
Understanding the hard side means recognizing their unique needs and motivations. They seek tools that simplify their work, recognition, and rewards. Killer products focus on doing one thing exceptionally well—like Zoom’s seamless video calls or Tinder’s swipe interface—creating magic moments that delight users and encourage repeated use.
These magic moments trigger viral loops, turning early adopters into passionate evangelists. Engagement ladders encourage users to deepen their involvement over time, while referral programs accelerate acquisition. The synergy of power users and killer products is the engine behind explosive network growth.
For product teams, the lesson is clear: identify your hard side, solve their hardest problems with simple, reliable products, and nurture those relationships to unlock unstoppable momentum.
