The Cold Start Problem (2021) is a book by Andrew Chen on business & strategy. A16z partner Andrew Chen dissects how network-effect products beat the cold start problem. Drawing on Slack, Uber, Tinder, and Zoom, he maps the five stages every network passes through, from empty room to escape velocity to eventual ceiling.

Why it’s on the shelf

The definitive playbook for the hardest problem in tech: getting a network effect to ignite from absolutely nothing, then keeping it from collapsing once it does.

Two of the ideas you’ll keep

The Clif summary of The Cold Start Problem pulls out 7 insights. Here are the first two.

  1. The Cold Start Problem is the paradox that a networked product is worthless until enough people use it, but people won't use it until it's worthful. Chen's answer is not to launch big but to ignite a single self-sustaining 'atomic network', the smallest stable unit that can survive on its own.
  2. Every network product moves through five stages: The Cold Start Problem, Tipping Point, Escape Velocity, Hitting the Ceiling, and The Moat. Each stage has different physics, so the tactics that ignite a network are the opposite of the ones that scale or defend it.
